I decided to build an HTPC to play games and video in 4K, hence the necessity for the Fatal1ty ITX motherboard which is the only one in ITX form factor which has an on onboard HDMI 2.0 HDCP 2.2 compliant compatible with new Bluray 4K units on the market (external) paired with a 7700k and a 1080 Ti.
I have seen several builds of the Evolv Shift, mostly I wanted to include some parts which I liked a lot, like the Kraken X42 and the Corsair Vengeance RGB, but the Kraken X42 is mostly incompatible with this case, solutions for this problems appear to be just install the Kraken and let it protrude from the rear side, but in that situation the panel would not close, and you risk damaging the glass for being in contact with the radiator, or cramp all the cables up the tray and install the PSU above the radiator.
Needless to say that building in such a tiny space posed all kind of problems, notably the PSU location, because the interference of the radiator with the power button of the PSU I let the PSU protrude from the case a little in the space for the ventilation, otherwise the button could not be fully pressed. Also routing the cables for GPU for the rear part of the case and cramping all the cables in the cable tray of the case let me finish the build, but the PSU appears inclined which doesnt bother me a lot.
For heat management I used Noctua 140 industrial fans 2000 RPM in push-pull configuration, which helped to get air into the case (intake), and the phanteks case fan for exhaust.
As my focus is 4K gaming, I tested the system in various configurations, first with the Graphic Card with fans looking to the rear panel but without the panel to try it open air, and the card hits 82-84 C just by playing some minutes of Shadow of Mordor, obviously MSI Armor is the worst 1080 ti in thermals so it was expected. Finally decided to go as Phanteks recommends with Graphic Card fans looking at the inside of the case, and im getting the same temps for thermal throttling which in my opinion doesnt impact my gameplay too much, I will add a Noctua industrial fan 3000 RPM shortly to try to get out as much hot air as possible just to protect my other parts, even though I know my card will ALWAYS be very hot in 4k.
I will recommend that if you plan to build in this case for 4K and want to show a nice build with good temp, use the Deepcool Captain 120 EX RGB for the looks, a 1080 Ti with AIO as the Seahawk because both radiators are of 120 and 27 mm thick which are compatible with the case, or a cheap card with Kraken G12 and something like Corsair H55.
