This machine is mostly for gaming with some Windows web testing thrown in. I pretty much lived on /r/buildapcsales for the last couple of months to get the best prices on what I got. I can't recommend that board enough. I also salvaged the PSU and CPU Cooler from my previous machine. That is an older i5-3570k with a 1060 that the kids are going to use. Prior to this build, that machine was my gaming rig, the family's Plex server, and my testing machine.
I went back and forth on ATX, Micro ATX, and Mini ITX and finally settled on the Mini ITX because of this case. I got the non "i" version because I didn't want the NZXT Cam software after hearing all the trouble people have had with it. I am still waiting on a few fans (and the PWM splitters) along with an NVMe drive. I am keeping the RGB minimal with a white/orange theme. I may also add in some custom cables at some point, but for now the black ones that came with the PSU work just fine.
The case was really nice to work in. I've been hearing people refer to larger ITX builds as "Full ITX" and I can get behind it. There is a ton of room in this case without feeling over-sized. It fits on my Ikea desk just fine and I don't feel overwhelmed by it being up top. And if you get this case, you'll want to show it off. Most of the nice parts of this case have been covered by reviews and other builds (the really nice layout for front radiators, the amazing amount of depth for good size GPU's, the decent airflow). There are a couple of things that I hadn't seen mentioned before that I want to call out. If you have an SSD you want to show off in the front panel, make sure that the power and sata cable are to the right of the SSD manufacturers logo so you don't have to turn it upside down to hide the cable or have the cable running to the other side of the case. Neither looked good in my case so I put the SSD on the back. Included in the hardware was a nice "nubbin" (that is adjustable) for your GPU to rest on. It attaches to the PSU shroud and works really well. As many other people have said, make sure your Mobo has either a ton of fan headers (not likely) or a plan to split or manage them another way.
I have successfully "overclocked" my CPU to use the "Max Turbo Frequency" all the time (well it says 4.3 GHz and I have the multiplier set to 4.2, but it's stable and doesn't drop). I never really used the overclocking on my other i5 chip and so it isn't the most important thing to me. I do like the speed on this chip, though. I was able to get a better deal on it than the typical 8400.
The only real challenge I had was with last year's Corsair H60 CPU Cooler. This is the non-rgb version and is a great little cooler for any CPU. I have read on a number of forums (after I started my build) that this isn't compatible with Coffee Lake processors and that it wouldn't fit snugly. I found that the problem wasn't with the processor, but with the motherboard being thinner than my old 1150 board. I solved this by adding a couple of washers on the back to get the standoffs snug against the mobo. Once that was done, it fit snugly and is working great.
Just about the best thing (to me) was that when I put it all together, it posted to the Bios first thing! I named it Finn because of the small stormtrooper look (though maybe it ought to be Luke... hmmm). I'd love to hear your thoughts and answer any questions you might have. Just be aware my answers might be "because it was a good deal" or "I don't know, I just thought it would be cool".
Edit: I added a couple of light strips for the interior. Nothing flashy, just dim illumination.
