Looks nice man! I've heard those Dark Rock 4 coolers are good, but if you didn't mention it, I wouldn't even know you had RGB RAM. Maybe save the loose change for a while and get a larger AIO (240 or 280) sometime later?
I would have loved to see some pics of that ITX board with that Dark Rock on it before you put it in.
I love pics of ITX boards being used in silly situations out of necessity! Here's a pic of when I first got my Corsair 750D. The only board I had working at the time was an Asrock Z87 board (which now belongs to my wife, Kayla).
