Your models run when you say — never deprecated, revoked, or rate-limited. Weights on your disk are yours for good.
Prompts never leave the building. Nobody trains on your work. Private by physics, not by policy.
Own the machine and inference has no meter. No per-token bill — agents run around the clock.
Fine-tune on what only you know. The model becomes an asset you own — and sells with the company.
We build the hard part, you supply the rest. Four things come in the kit: the case, the risers, the cooling, and the power, machine-fitted to each other, tuned and burn-tested as one build. You add your own motherboard, CPU, memory, storage, and graphics cards, then assemble and run.
Two kinds of chassis, one for each job. The desk builds are milled from solid aluminum billet and anodized by hand. The case moves heat like a heatsink, and the triangular cutouts keep it stiff where it matters, light where it doesn't. The rack goes another way: steel, hot-swap fans, front drive bays, built to be serviced rather than admired.
Every card gets its own PCIe 5.0 riser at a full Gen5 x16, straight from the CPU with no switch in between. No card shares lanes, drops to x8, or waits on another. The risers are cut to length on the desk builds and run over MCIO 8i cables on the rack, routed clear of the airflow.
Power that scales with the machine. The two-card runs on a single supply and a standard outlet. The four-card uses two and needs a 240V circuit. The rack runs four redundant, hot-swap supplies into a distribution board that splits clean power to every card, also on 240V. Anything past the two-card needs 240V, sorted before the machine arrives.
Air moved on purpose. Cards packed this close make heat that has to leave in a straight line, so the fans are mapped to the chassis before a panel is cut. The two-card runs six fans, the four-card eighteen, both wired to one controller and matched to the airflow path through the case. The rack runs a wall of twelve hot-swap fans, eight 8056 and four 8038, PWM temperature-controlled so they work only as hard as the load asks.
Open-source hardware
Every CAD file, bill of materials, and BIOS setting — free on GitHub. Fork it, change it, build your own, even sell it. This is how the personal computer began: in the open. We’re doing it again, for AI hardware.

So you can choose them yourself. CPU, GPU, memory, and storage needs vary a lot by workload and budget, and prices on cards move week to week. We build the hard part, the chassis, risers, cooling, and power, and leave the rest open so you spec it to what you actually run instead of paying for a config that does not fit.
We’ve tested the RTX 3090, 4090, 5090, and RTX PRO 6000, with clearance and power notes for each. Any card that fits and has the power will run — the list is there to help you choose, and it grows with every new build.
Yes, that’s part of the point. If your motherboard, CPU, memory, or cards still do the job, bring them over. Just check two things first: that your board fits the chassis form factor the kit supports, and that the power in the kit covers the cards you plan to run. Tell us what you already have and we’ll confirm it works before you buy.
Depends on the size. The two-card runs on a standard wall outlet. The four-card and the rack both need a 240V circuit, not a standard outlet. That is normal at this scale, but it is the kind of thing to sort out before the machine arrives, not after, so plan the outlet ahead if you’re going for the four-card or the rack.
Yes — you can run different cards side by side, like a 3090 next to a 5090. The best way to set them up depends on what you’re running, so tell us your workload and we’ll help you plan the layout.
You replace it yourself in a few minutes: open one panel, swap the card, done. Nothing to ship back, no ticket to file. The machine is built to outlast any single card.
