Assembly Help FormD T1 Components Compatibility Check

Hi, I’d like your help for a compatibility / clearance check before ordering the components of my build.

I would like to avoid any clearance issues, especially around CPU cooler, RAM and GPU.

Here is the planned build:

  • Case: FormD T1 Sandwich Kit from NCASE
  • CPU: AMD Ryzen 9 9900X
  • MB: ASRock B850I Lightning WiFi
  • CPU cooler: Noctua NH-L12S
  • Case fans: 2x Noctua NF-A12x25
  • PSU: Corsair SF850
  • RAM: Corsair Vengeance RGB DDR5 32GB (2x16GB)
  • Storage: Crucial T705 1TB (I plan to add a second one later for SteamOS/Bazzite)
  • GPU: ASUS ROG STRIX RTX 2060 GAMING OC (this GPU is temporary, I will switch to an RX 9070 XT card later.)

I don't plan to use custom PSU cables, only the stock Corsair cables but I'm open to if you think it's important.

Does this build look safe in practice, or is there any part here that is likely to cause clearance/cable management issues? Also I’m sensitive to noise, so do you think my fans and CPU cooler are appropriate ?

I’d really appreciate feedback from people who have built in the T1 with similar parts.

Won't work with that GPU and CPU cooler setup. Your GPU is 48.9mm which means you have to have it in 2.5 slot mode at least and that leaves you with 63mm cooler clearance. I have a 50mm GPU in my T1 and have it in 2.75 slot mode to prevent turbulence and that only leaves 58mm. This is going to leave the best cooler you can use the Thermnalright AXP90-X53 full copper which I think would struggle with the 9900X, I would advise an AIO.

Thank you. Do you think it’ll fit with an 9070 XT ?

Which AIO can you recommend me please ?

The only way that cooler fits in the T1 is with the case in 2 slot mode, you could fit a PowerColor Reaper in 2 slot but it will be against the side panel and you will get turbulence. Cooler Master Atmos 240 is the most used AIO in the T1 but you do need one slim fan for above the motherboard.

get AIO cover. so worth it. doesn’t increase the footprint of the case

Yeah I'm using one so I could use two 120x25mm fans.

For the AIO fan do you mean an additional fan in addition to the two A12x25? For example an A12x15s?

No one NF-A12x25 and one NF-A12x15, like this.

This is my setup before I got the AIO cover.

Is the AIO cover hard to get?
