Recently completed Intel i9 build. Love the Lian-Li O11 case. Very well thought out and great space for cable management.
Originally tried using a Gigabyte Z390 motherboard. After installing everything, kept getting a DRAM error light on the mobo. Tried resetting the RAM, resetting the cpu, gpu, battery, etc. but no luck. Couldn't clear the error and enter BIOS. As a last resort, tried unplugging everything and switching to an Asus Maximus XI Hero board that I ordered, and viola, booted up the first time. I'm not sure what the exact problem was with the Gigabyte mobo, but you gotta love Amazons return policy.
Went with the side exhaust for purely aesthetic reasons. Top and bottom fans are intake. So far, temps are stable. True test will be when I do the overclocking, will make adjustments as necessary. Hard-line water cooling will be the next future task.
Original motherboard had one USB on the mobo, got an NZXT USB hub (works perfectly and hides away between the PSU and storage cage). Commander Pro tucked neatly under the PSU. I like the RGB controls using that with the icue software.
Cable Mods give it a nice clean look. Perhaps I will use a white cable sleeve on the AIO. Overall, very pleased how everything turned out. Now to put it thru it's paces to see what it can do!
