I originally built this into a Dan Case A4, but I just couldn't get the CPU sufficiently cooled. I had no access to the 92mm Asetek AIO where I lived, so I decided to just change the case altogether and go for a bigger air cooler. System's running nice and cool now.
I was aiming for a 4k gaming rig with this since I already had a pretty good 4k monitor for work, but unless the game is well optimized it is tough to keep a steady 60fps. I bought an affordable 1440p 144hz monitor, and this thing crushes at that resolution.
