I have a few things I'll be adding additional in the future. First and foremost, I'll be custom sleeving a set of cables to minimize the crowded nature of an mITX case. I plan on adding a full Watercooling setup consisting of a 180mm dual in front looped to a 140mm single in the rear for full CPU & GPU cooling. This will be fairly easy since using the SFX form factor PSU leaves a TON of space available for a pump/res combo. I wanted to be sure I was going to have room prior to going for full watercooling.
The case is surprisingly roomy for it's size. The one thing I didn't like was how rigid the USB 3.0 cable is for the front panel, which I might even remove once Watercooling is in. It's pretty much impossible to hide due to it's length, and it's tough to work with because it doesn't flex. I may just find a way to replace it with a more standard USB 2.0 cable since the rear has 2 USB 3.0 and I don't have enough 3.0 peripherals to bother needing the extra 2.
I'm getting idle CPU temps of 27-30 degrees Celsius and I have not seen temps over 40 degrees at load. GPU sits around 35 to 37 idle and has not gone above 67 degrees at load while gaming so far which confirms the case airflow is pretty good. I plan on running a series of benchmarks later tonight and see how it handles under stress. Windows Experience rates 7.6 out of 7.9, so I'm pretty happy with this build for the price and style.
