Thank you. I put the RGB lights in it for additional lighting when I need to work on it. The remote allows me to switch it to white and turn up the brightness. The lights are off most of the time, but with the black aesthetic, I needed to have the ability to see what I was doing. The black is themed based on the game No Man's Sky for the Atlas.
The rack that I chose is this one: NavPoint 22U IT Wall Mount Network Server Rack
This is the one I got. It works great with leds.
Afraid I don't know exactly what he uses, but I can speak to personal experience with this rack:

Wasn't too hard to assemble, and rolling casters are super useful.
Where do people find a 30 inch depth 15-25u rack for a reasonable price?
Something like this but 30inchhttps://www.amazon.com/NavePoint-Network-Cabinet-Locking-Casters/dp/B01A6JQ5D0/ref=sr_1_7?keywords=server+rack&qid=1561779255&s=electronics&sr=1-7
One like this is $700...
