Originally built in late summer 2015, I've since added a 5TB WD Black HDD and a used Dell E2011H as a second monitor.
The 390X still handles games great at 1080p and 144hz, and works quite well with VR for playing games such as Space Pirate Trainer and Audioshield.
The case itself is very solid and well-built, and despite its small size it's easy to access the inside. It is rather heavy for its size, however.
My only caveat with this build is that I was forced to put the 390X on the top PCI slot since it would overheat when too close to the bottom of the case. Unfortunately this means that the CPU's heatsink was then pushing slightly against the GPU, but it hasn't caused me any problems so far.
I've since overclocked the i5 to 4.5 GHz.
