Hello All,

Here is a pic of the final build of my open air PC build. I built the case about 5 years ago and have been running a 10900k.

I have stepped up to a 9950X3d and the Asus Crosshair ROG 2006 X870E motherboard.

I have 3 x 360mm radiators and a pair of D5 pumps in series.

Let me know if you have any questions! J

How did you find the right spacing for the motherboard holes?

[-] Jsunn@lemmy.world 1 points 58 minutes ago

I had an old ATX motherboard and I traced the holes.

This is easily achieved with a ruler and technical schematics.

Thanks, but I was hoping for a more detailed response. I'm not disassembling my PC to measure the hole spacing, and I've been unsuccessful in finding what the standard spacing is.

This is the first result I got for "ATX Specification": https://scidyne.com/ftp/ref_info/atx_201.pdf

There is a diagram with dimensions on page 11
