The FormD T1.
One case. Every build.
The iconic 9.95L sandwich-layout chassis, engineered for enthusiast SFF builds.
Systems from $2,224
FormD T1 V2.1A tower's worth of hardware, shrunk to something you'd actually want on your desk.
Big cases are easy. Anyone can leave room to spare. The FormD T1 does the hard thing — it packs a full-length flagship GPU, an ATX-class power delivery, and proper liquid cooling into roughly 9.95 liters, then wraps it in machined aluminum you can carry in one hand.
That is why we build on it — and only it. When you standardize on the best chassis ever made for small-form-factor, every system that leaves the bench inherits its rigidity, its thermals, and its presence.
The sandwich layout that changed small-form-factor forever.
Sandwich interior
Hand-builtSix reasons the T1 is worth obsessing over.
Sandwich architecture
The motherboard and graphics card sit back-to-back on either side of a central spine, connected by a PCIe riser. It is the layout that makes a full-length GPU fit beside a full ATX-power system.
Aircraft-grade aluminum
A CNC-machined aluminum frame and brushed, anodized panels. Rigid, feather-light, and finished to a tolerance you feel the moment you lift it off the desk.
Full-size GPU, no excuses
Room for oversized, triple-slot flagship graphics cards on a vertical mount — the same silicon you would run in a tower, in a case you can carry with one hand.
Serious thermals
Clearance for a 240mm or 280mm AIO or a low-profile air cooler, with mesh panels that turn the whole chassis into an intake. Small volume, real cooling headroom.
Modular by design
Swap side and top panels between solid, ventilated mesh, and glass. Reconfigure the internal layout for air or liquid. The T1 adapts to the build, not the other way around.
Built to outlast trends
No RGB gimmicks, no plastic. A timeless monolith that will still look right on your desk long after this year’s hardware is old news.
Your T1, your palette.
Every system is finished to order in anodized colorways, with your choice of side panels and sleeved cabling. Same legendary chassis — unmistakably yours.

Zero guesswork
Every clearance, cable length, and fan curve is dialed for this exact chassis. Nothing is improvised.
Hand-built for the T1
Custom-cut sleeved cables and a torque-controlled assembly process tuned specifically to the T1 interior.
Tested as one machine
48-hour burn-in and thermal validation on the finished T1 build — not a spec sheet, a real system.
