I finally got a 4K TV and a bunch of 4K components to go with it so I decided to build a 4K gaming system also.
Case: I had a hard time settling on a chassis with space constraints in both size and depth to fit my media cabinet. In a perfect world I would have preferred a deeper version of the Lian-Li Q19 that supported full length GPU's. I ended up going back and forth between the Silverstone RVS02/ML08 and the Node 202 until I saw a RVZ02 at my nearby Microcenter and I was not impressed but how cheap it looked, they really need an updated FTZ model.
GPU: The choice of a blower style GPU was another difficult one, I had considered the EVGA 1080 TI's since they stuck to a two slot design in their custom heatsink models but I was still concerned with where that hot air would end up going.
Storage: Lastly was storage, for movies and what not I have a storage server holding everything so that just left games for local storage. The new Xbox I got came with a 2TB drive and seeing how quickly those 50GB installs ate up space I didn't like my options. If this case had supported a taller/enterprise 2.5" drive I would have gotten one of those but with only laptop height drives, 2TB was also the best I could do for this case, and SSDs at 2TB+ sizes aren't a financially reasonable option yet. My decision was further backed up after looking over several benchmarks showing that the only penalty for the spinner would be level load times. Also, even though the drive I selected is already a hybrid SSHD I was intrigued to see how it would perform with an additional caching layer, we'll see how that works out.
Status: Still waiting on the Optane drive to ship but I finished the build for now.
The thermals are what I expected, running Prime95 the CPU will hit the throttle limit but normal gaming temperature are "reasonable". The GPU hits the default thermal limit with Furmark and normal gaming but the intake fans do keep the TDP at nearly 100% vs 80% without them running.
