This is my very first build, and because of a small room and hence a small desk to work with, I chose the Mini-ITX form factor. I had been eyeing the Dan Case when I was planning my build back in April of 2018, and since v3 of the A4-SFX was to be released in late May, I decided to wait a little while.
I chose the i7-8700 because neither did I want to void my warranty for an 8700K nor do an AIO on my first build, as some other fellow builders have done in the past with success. As for the GPU, the dual-slot GTX 1080 ti I went with was the EVGA FTW3, which had a max GPU length of 300 mm, while the case allowed for 306 mm, so it was a tight squeeze indeed.
Aside: if you plan on using this GPU with this case, just keep in mind that when installing the GPU, the top part of the case (not just the top cover) has to be disassembled due to the GPU's height.
Overall, assembling the system was a smooth process. The only difficulty was the stiff cables of the Corsair SF600 PSU, which led to slightly tricky cable management. I could have went for custom cables, not only for the greater wire flexibility but also for the shorter length, particularly for the SATA power cables that ran a mile through the case. But the out-of-the-box PSU cables sufficed.
Thermal performance is not bad: the CPU idles at around 35 degrees but under load goes up to the high 70s at about 4.50 GHz, which should be fine. At first I naively placed the system next to a wall with the motherboard side a few centimetres from it, causing CPU temps to hit the 90s, so I would recommend following the manual's recommendation of maintaining a distance of at least 15 cm between any large surface and either side of the case. As for The GPU, it idles at around 42 degrees which may seem a bit high, but it does so with the fans completely off using stock fan curve settings. So combined with a Noctua fan, the machine is dead silent during low-intensity workloads. The GPU on full load caps off at a bearable 74 degrees.
Other details of the setup, but not of the build itself, include an ASUS ROG Swift PG279Q (1440p, 165 Hz) with a Vivo single-monitor desk mount, a HyperX Alloy FPS Pro Tenkeyless (MX Blues), a SteelSeries Rival 100, Creative T20 Series II 2.0 speakers, and a pair of Beyerdynamic DT 770 Pro 32 Ohms.
