RISER CABLEPCIe 4.0 X16 (185mm)
GRAPHHICS CARD COMPATIBILITYGPUs no more than 140×325mm, 3.25-Slot thick. (Graphics card thickness depends on CPU cooler clearance)
CASE FANS SUPPORTEDTop: 2x 120mm
Side: 2x 120 / 140mm (based on components)
LIQUID COOLING SUPPORT1x 120mm
1x 240mm
2x 240mm (requires a separate kit)
1x 240mm + 1x 280mm (requires a separate kit)

Note: Dual radiator setups require a single slot GPU waterblock. Due to this GPU limitation and build complexity, this is not recommended for most users.
POWER SUPPLY SUPPORTSFX / SFX-L (SFX-L not recommended with AIO or custom liquid cooling)
CASE REVISIONSV2.1 Updates:
– Two extra screw holes were added for v2.1 side fan + radiator bracket brace. This feature was added for dual radiator builds where the second radiator is mounted to the GPU side.
– The power supply bracket mounting holes on this bar are now threaded. This allows the SFX bracket to install more securely.
– The rear panel M19 holes are now through-holes are no longer threaded.
– The GPU lock bars from v2.0 have been replaced with GPU lock brackets. These brackets allow for better GPU cable (DP, HDMI) clearance compared to the old bars.

FormD co-owners / designers 3FC & W360 have split operations, with each now operating their own respective websites. See the history of FormD.

We encountered a compatible issue between the T1 and our LOBO CPU waterblock. The LOBO mounting screws protruded too far through the motherboard backplate. This can pierce and damage the riser cable as it did with ours. Modultra has confirmed this issue with some earlier LOBO units and the current revision uses shorter mounting screws at 31.75mm. You’ll need a custom GPU side radiator bracket or cable ties when using rear QDC assemblies, due to clearance issues. FormD is working on a solution. We found zip-tying through the Noctua fans and around the case struts works very well in meantime.

CONCLUSIONS

FormD T1 is widely considered one of the best small ITX cases and certainly one of the most popular among enthusiasts. The case provides satisfying build experience and multiple configurations, such as AIO, air cooling and custom liquid cooling.

For those looking to take on custom liquid cooling, you should look towards Festo 8mm pneumatic fittings: NPQH-DK-G14-Q8-P10 (578377), NPQH-L-G14-Q8-P10 (578284), with 8mm tubing: PUN-H-8X1,25-SW (197392). Spacers may be required to reduce the fitting thread length for some hardware (radiator, CPU block etc), we recommend Barrow 1.5mm Mini Spacers.
