/////////////////////////////////////////////////////////////////

Update: 11/8/2026:

I have created an assembly guide for this mount here: https://github.com/NexGen-3D-Printing/SteamMachine/discussions/72

If you have any questions, you can ask me in that thread.

Sorry for the delay everyone, I'm just extremely busy at the moment.

This is the latest version of my Thermalright Aqua Elite mounting system for the BC-250 single board computer.

This one is specifically designed for the Thermalright Aqua Elite original (V1) the V2 and the V4, none of the other Thermalright coolers will fit properly, but there are many other types from other manufacturers that will fit just fine, however, if you are building my PRO-V2 case, then you must use the recommend Thermalright AIO kit due to the height.

BOM:

• Very Specific Threaded Inserts 24 x M3 x 3.5x4.6x6mm

• 12 x M3 x 14mm Socket/Pan/Button Head Bolts

• 4 x M3 x 50mm Socket/Pan/Button Head Bolts

• 4 x Springs: Diameter 6mm - Length 10mm - Wire Thickness 0.9mm

Parts to Print:

• 4 x  Thumbnut - Back Plate Retainer

I print mine from PET-CF with PETG-GF for the coloured Accents
