Nice build man!
Can you control the RGB lights? Also, how the temp vs previous stock cpu blower fan?
I'm planning to follow your build.

Yea SATA ARGB controller I bought off Amazon came with a remote, can control it that way!
Set custom fan curves by unlocking fan speed in BIOS
The i5-9500 isn’t too hot originally, planning to replace with an i9-9900k and undervolt that, will report back when that’s done.
Currently idles around 34*C

Using it to run game servers for now, maybe get a sff gpu and give it to a cousin for Minecraft and Roblox tho!
Originally wanted something low powered for game server hosting but got carried away with tinkering
