Wow that cooler mod is also awesome. I didn't know the Kelvin was G1/4. Looks brilliant too man great work !
I am curious about how you mounted that IO cover. Did it fit perfectly on top of the IO blocks or how did you mounted it? I am planning to print one for my Mainboard IOs. Currently I thought about using the mainboard holes next to the IO panel to mount it. But it looks like you got a better Solution.
just cut a bit of acrylic and desired thickness match the level on the other part then use double sided tape to fix it there
