The House's Gear · The Congregation of Tomorrow

A plan, not a purchase. Nothing here is bought by anyone but the house, and nothing is asked of thee: the house buys its own gear, a part at a time, from its own pocket. Prices were seen on the day each card says and will move; every one links to the page it was read on. Brand names are examples of a kind of part, not endorsements.

5steps, a little at a time

I · What the house runs on now

The house server: A small office desktop (HP EliteDesk 800 G3 SFF: Intel Core i5-7500, 16 GB memory, one 512 GB NVMe drive). It carries the house's records, its library and its services, day and night. A good machine of a kind sold by the million: every part is standard and every part can still be bought.
Its backups: One 1 TB USB SSD plugged into the server for the nightly copy, and a full copy kept away from the house, locked up, in the hands of someone outside the household. Every copy is refreshed and read-checked once a year, on 6 September. What it still needs: a restore from it proved on a spare machine, and a second drive so a copy is always away while the other is refreshed.
Its network: Its gigabit port links at only 100 megabits: a tenth of what it can do. That is nearly always a worn cable or a slow switch port, and it costs a few dollars to mend.
Its power: Straight from the wall. A blink of the power stops everything mid-write, and nothing protects it from a surge.
The work machine: One laptop (Ryzen 5, 16 GB), which is also where work is done.
The phones: Five Android phones in the household's hands.
The record's keeper: The sun-powered Hundred-Year Node is drawn on the Blueprints, not yet built.

II · What the gear must do

Keep running through the short outages Florida gets, and shut down cleanly in the long ones.
Lose nothing: every record on two disks inside the server and on one copy kept away from the house.
Be mended by anyone in the house with a screwdriver, from parts any store sells, without a technician.
Draw little power, so the bill stays small and a battery can carry it.
Work together: one power line, one network, one backup routine, nothing that needs its own app or account to run.
Be ready for the future by being plain: standard parts, open formats, nothing that stops working if a company does.
Stay in the household's reach: no part dearer than a month's spare money, and the whole bought a little at a time.

III · How it all fits together

Power runs one way: the wall feeds the battery backup, and the battery backup feeds the server, the network switch and the internet box. In an outage the battery carries all three, and tells the server when to shut itself down.
The network is one small switch: the server, the internet box and the laptop all plug into it with tested cables.
The records live on two drives inside the server, each a copy of the other, so one can die without loss. Each night a copy goes to the backup drive; once a month that drive changes places with a second one kept away from the house.
Once a year the core is burned to M-DISC and kept apart, readable with no power and no internet.
The Hundred-Year Node stands on its own sun and battery, and takes its copy over the network when the network is there.

IV · The power, worked out

The UPS is rated 1500 VA / 1000 W: far more than a small server, an internet box and a switch will ever ask.

The real draw is not guessed here: once the UPS is in, its own screen shows the watts, and that number goes on this page.

In a long outage the UPS tells the server to shut down cleanly. The server waits, whole, for the power to come back.

Every part

Each part is a card: what it does, why this one, its price and where it was seen, its power, how to fix it, what it works with, how long it lasts, its spare, and what it is made from.

V · Get now: the core

What protects the house today. The Elon lane's cut, priced and sourced.

This tier: $486 + $80 to $150 (rough, not yet sourced)

No. 01 · First: stop the loss

CyberPower CP1500PFCLCD PFC Sinewave UPS

CP1500PFCLCD

What it does: Line-interactive pure sine wave battery backup (1500 VA / 1000 W) for server, router and switch; rides out short outages and allows a clean shutdown over USB.
Why this one: Florida blinks and storms stop the server mid-write. This carries the server, the internet box and the switch, and tells the server to shut itself down before the battery runs out. Its own screen shows the watts drawn, so no separate meter is needed.
Price: $240 · Amazon, 2026-11-03, sold by Amazon.com; SALE: 13% below the $274.95 list price (CyberPower MSRP also $274.95).
To fix it: User-replaceable battery (CyberPower: RB1290X2, or RB1280X2B by serial); 3-year warranty including batteries; 4 ms transfer time; 12 outlets (6 battery).
Works with: The server (over USB, for the safe shutdown), the internet box and the switch, all on its battery side.
How long it lasts: The battery about 3 to 5 years; the unit far longer.
The spare: A replacement battery pack of the same model, when the first one tires.
Cheaper choice: CyberPower CP1000PFCLCD (1000 VA / 600 W, same family) · $180

No. 02 · First: stop the loss

Monoprice SlimRun Cat6A patch cable, 3 ft, 5-pack

Monoprice 136200 (30 AWG, snagless)

What it does: Fresh certified patch cables for server, router and switch; a bad cable is the usual cause of a 100 Mbps link.
Why this one: The server's port runs at a tenth of its speed, and that is nearly always the cable. Swap it first, before buying anything else.
Price: $16 · Amazon, 2026-11-03, sold by Amazon.com; SALE: 20% below the $19.68 typical price.

No. 03 ·

A second server, kept at another house

What it does: A used machine of the same model, kept away from the house, that takes a copy of everything every night.
Why this one: The best idea in this plan. The away copy is never more than a day old, and the machine can take over if the house is lost. It is also where the quarterly rebuild is practised. One box covers a dead power supply, board, memory or drive at once.
Price: price not found
To fix it: Every part is the same as the server's, so either machine can lend the other a part.
How long it lasts: Seven to ten years.
Made from: Chips and computers (office mini-PC: HP EliteDesk, Intel N100 mini-PC): Quartz to silicon metal → Polysilicon to silicon wafers → Wafer fabrication (the chip fab) → Assembly, test and packaging of the chip → Boards and final assembly of the PC → To a shop in Florida

IX · From the ground to the shelf

Every part on this page is made from something dug out of the earth. These are the chains, from the raw material to the finished thing, with where each step happens and who does it. Each card above names the chains it is made from.

Chips and computers (office mini-PC: HP EliteDesk, Intel N100 mini-PC)

Quartz to silicon metalQuartz (silica) is smelted with carbon in electric furnaces to make silicon metal. A small part is purified further into ultra-pure polysilicon for chips and solar cells.China: almost 80% of all silicon materials, 2025 (USGS text); about 87% of silicon metal, 2025 (calculated: 4,000 of about 4,600 thousand t) [source]Brazil, Norway, Russia (next largest silicon-metal makers): about 4%, 3% and 1% of silicon metal, 2025 (calculated) [source]not found by name in USGS (company data withheld) USGS Mineral Commodity Summaries 2026: Silicon

To a shop in FloridaFinished PCs are shipped from the assembly country to US distributors and retailers. The port of entry and route into Florida were not found in a citable source.not found

The weak link: Making the most advanced chips: in 2022 almost all advanced logic capacity (below 10 nm) sat in Taiwan and South Korea (SIA/BCG 2024: 'from almost 100% distributed between South Korea and Taiwan in 2022'). Upstream, China made almost 80% of the world's silicon materials in 2025 (USGS MCS 2026, Silicon).

Memory and drives (DRAM, NAND SSDs, hard drives)

Silicon wafers (same start as chips)Memory chips start from the same silicon and wafers as the chips chain. Hard drives also need aluminium or glass platters, magnetic coatings and rare-earth magnets (not researched here).China (silicon materials): almost 80%, 2025 [source]see chips chain USGS MCS 2026: Silicon
DRAM memory fabsDRAM (working memory) is made by three big companies. Capacity is concentrated in South Korea; Micron makes most of its DRAM in Taiwan.South Korea: DRAM 'highly concentrated' there (no single % given in the text); US share 3% now, 9% by 2032 [source]Taiwan (Micron): a majority of Micron's DRAM output, 2025 [source]Samsung, SK hynix, Micron SIA/BCG 2024 Micron Form 10-K FY2025, Item 2 Properties
NAND flash fabs (the chips inside SSDs)NAND flash is made mainly in South Korea and Japan. Kioxia and Sandisk (spun off from Western Digital) share fabs at Yokkaichi and Kitakami, Japan. Micron makes NAND in Singapore.South Korea and Japan: South Korea 30% of NAND capacity (2022), 42% by 2032; Japan + Korea about 75% by 2032 [source]Japan (Kioxia Yokkaichi and Kitakami plants, joint venture with Sandisk): not a share [source]Samsung, SK hynix, Kioxia, Sandisk, Micron Kioxia news release, 30 Jan 2026 Micron Form 10-K FY2025, Item 2 Properties

The weak link: Memory chip fabs in South Korea: DRAM 'will remain highly concentrated in South Korea', and South Korea plus Japan are set to hold about 75% of NAND capacity by 2032 (SIA/BCG 2024). Hard drives rest on just two makers whose assembly is mainly in Thailand, China and Malaysia (Seagate and WD 10-Ks).

Lead-acid batteries (inside a UPS such as CyberPower or APC)

Lead ore miningLead is mined mostly together with zinc and silver. China mines the most.China: about 42% of mine output, 2025 (calculated: 1,900 of 4,500 thousand t) [source]Australia: about 11%, 2025 (calculated: 480 of 4,500) [source]Peru, United States, Russia, India: about 6%, 6%, 6%, 5%, 2025 (calculated) [source]not named by USGS; US mines are in Missouri, Alaska and Idaho USGS MCS 2026: Lead

The weak link: Refining: China refined about 48% of the world's copper in 2025 (calculated from USGS MCS 2026, Copper: 14,000 of 29,000 thousand t). Mining is spread wider; the largest miner, Chile, had about 23%.

Tool steel (S2 or chrome-vanadium screwdriver bits)

Iron ore miningIron ore is mined and made into pellets or fines for blast furnaces. Australia mines the most.Australia: about 38% of usable ore, 2025 (calculated: 980,000 of 2,600,000 thousand t) [source]Brazil: about 16%, 2025 (calculated: 420,000) [source]India, China: about 12% and 11%, 2025 (calculated) [source]not named by USGS USGS MCS 2026: Iron Ore

X · Easy to fix, on purpose

Standard parts only: memory, drives, cables and power that any computer store sells, so a dead part is a trip to the store, not a lost machine.
Every part has a spare on the shelf, or a cheaper stand-in named on its card.
One screwdriver kit opens everything on this page. The server's case opens by hand.
Every cable is labelled at both ends, and the labels match the drawing.
A watt meter tells the truth: measure the real draw before buying more battery.
Write down what was done, on the day, so the next person can follow it.
Keep the server and the drives off the floor, out of the garage, somewhere dry and cool. Free, and it beats most of what can be bought against flood and heat.
A printed sheet, kept by the server, for when the one who runs it is out: how to restart the server, the internet box and the phones, and who to call.

XI · The order to get the core in

Bought a little at a time, the most important first. Nothing on this list costs more than the house can carry in a month.

First: stop the loss · $256 (running total $256)
The battery backup and the second drive: the two things that stop a blink or a dead disk from costing the records.
CyberPower CP1500PFCLCD PFC Sinewave UPS, Monoprice SlimRun Cat6A patch cable, 3 ft, 5-pack
Second: the network and the off-site copy · $190 (running total $446)
The switch and tested cables mend the slow link; the second backup drive leaves the house.
Seagate Portable 4TB external USB 3.0 hard drive
Third: the tools to fix it all · $40 (running total $486)
So every mend on this page can be done at home.
iFixit Mako Driver Kit, 64 precision bits
Fourth: room to grow · $0 (running total $486)
More memory and the spare power supply, when the first three are done.
Last: the Hundred-Year Node · $0 (running total $486)
The sun-powered keeper of the record, drawn on the Blueprints, built when the house is safe.

XII · What wears out, and when

Part	Lasts	Then
UPS battery	3 to 5 years	a new battery of the same size slides in; the UPS stays
Hard and solid-state drives	5 to 10 years	replace one side of the mirror at a time, never both at once
The server itself	7 to 10 years	replace with the then low-power equal; the drives move across
Network switch	10 years and more	a like-for-like swap
Cables	until damaged	re-test once a year; replace any that fails
Backup drives	5 years	a new pair; the old pair is wiped and kept as spares
M-DISC copies	maker claims centuries (unproved)	test-read every 2 years; burn a fresh pair every 10

XIII · Left out on purpose

A rack, a NAS box, a second server: One good server with two mirrored drives and an off-site copy does the work. Two machines are two things to keep.
Anything that needs a subscription to run: If the company stops, the house must not stop. Every part here works with no account.
A generator: Fuel, noise, fumes and upkeep. A battery carries the short outages; in the long ones the server shuts down cleanly and waits.
Top-of-the-line parts: No part is chosen for speed the house will not use. The server is idle most of the day.
Smart plugs, cameras and gadgets: Each is another thing on the network to update and secure. None is needed to keep the record.
The seed sent to space: No safety per dollar. The record is kept by copies on earth, in more than one place.
A four-drive ZFS server: Two cheap machines in two places beat four drives in one box: one fire takes the whole box.
An HF amateur radio station: It needs a licence and a skill for each person. GMRS, on one family licence, and Meshtastic cover the family.
A 3D printer: It is not safety.
Ten-gigabit networking, cables in the walls, Wi-Fi 7 and a rack: The house moves little data. Gigabit and good Wi-Fi are plenty.
A second server in another room: Same roof, same fire, same storm. The second machine goes to another house instead.

XIV · The Elon lane's cut

The Elon lane's first-principles review of this plan, in two rounds (11-03): what to delete, what matters most, what breaks first, the order for the whole road, and the best idea. Its cut is the core above.

The best idea: Make the copy at the other house alive. A used machine there copies the house every night, so the away copy is never more than a day old and can take over if the house is lost. The locked-up drive stays as the cold copy, swapped monthly with a twin, and every three months the house restores from it to prove it works.
The one thing that matters most: Not making an away copy: the house keeps one already. Keeping it fresh (nightly), rotated (one drive always away) and proved (a restore every quarter).
Delete outright: The node parts and the M-DISC archive (a later year's project). More memory, until the server is shown to be short. A spare power supply: buy a whole spare server instead. The cable tester and the watt meter: swap the cable first, and the UPS shows the watts. Every tool beyond one good kit.
What breaks first: Power, in Florida storms and brownouts: the battery backup comes first. Then the drives. The house survives both by a written, practised rebuild from zero onto the spare server, timed, every quarter.
Ready for the future, without spending: Plain files and version history, so any machine can become the server. Standard, swappable parts only. Measure before buying. A backup that has not been restored does not count.
The whole road, most safety per dollar first: 1. Battery backup on the server and the internet, and a whole-panel surge protector. 2. Two security keys for each adult, with recovery codes in a fire safe. 3. The second machine at the other house, and a twin drive. 4. A 1 to 2 kWh power station. 5. GMRS radios and the family licence. 6. A dual-fuel generator. 7. Satellite internet for storms. 8. Then mesh radios, the spares shelf, the second node, and solar last.
Deleted from the house fully grown: The seed to space, ten-gigabit and the rack, a second server under the same roof, the four-drive array, HF radio and the 3D printer. Cut down: the AI machine to 'only if measured', one satellite messenger for the household, laptops only when one dies, solar last.
