Why I Built Gymtek

2026-03-19

Every project starts with a problem you can't stop thinking about.

Mine was simple: I wanted a compact, silent, capable home gym computer — something that could run training analytics, display metrics on a wall-mounted monitor, and not sound like a server rack. Nothing on the market fit. Either too loud, too weak, or too expensive.

So I started building one.

The First Prototype

The first unit was rough. A bare ITX board zip-tied to a piece of plywood, running off a salvaged PSU. It worked, sort of. Fan noise was terrible. Thermals were worse.

But it ran. And it ran fast enough — which is the only thing that matters in a first prototype.

The Noctua Mod

The noise problem had one obvious solution: replace everything with Noctua. Three A12x25 fans, a NH-L9i, and suddenly the unit was whisper quiet under load.

That mod became the +Noctua tier you see in the store today.

The Enclosure

Once the thermals were sorted, the enclosure became the focus. The goal was a box that looks like it belongs in a rack, not under a desk.

The STL files for the custom enclosure are almost ready. Once those are published, anyone with a printer can build the housing themselves. The goal is a fully open hardware stack — you buy the silicon and the build log, we provide the rest.

More soon.
