I just finished building the gaming rig using the mini ITX chassis from TT. I used a custom water cooling loop along with GTX 1060 SFF card to build this and I was actually surprised to see that you can install a custom water loop solution in such a small chassis. I chose the snow white version of the chassis to blend in with the desk which I am planning to purchase shortly. I re-purposed the parts from my earlier builds.
