For drawing, gaming, and hopefully one day 3D rendering. I boot Win10 currently as I wait for Ubuntu to steam out issues with Kaby Lake.
For those wondering about the case, you may be able to buy one going forward at SFFLab.com - I know they're planning on selling the DAN A4 eventually but they also have other good, small cases like the N Case which is what I would recommend if you want the smallest form you can still watercool (which you cannot without heavily modifying the A4). The A4 I have is a first-generation that I helped Kickstarter but it looks like they have a version 3 on SFFLab.
Ended up adding a Hue+ RGB controller with strips, a 500GB 950 EVO (to make room for the Hue+ - There is a spot for two 2.5in's under the PSU which happened to be the perfect size and spot to mount the Hue+; I was able to do this only by getting an NVME SSD for OS and using the additional 2.5in slot behind the front panel for my storage drive (currently just a regular 500 850 EVO I use to store the few games I find interesting) and some custom black PSU cables to help free up a little more room. Ended up messing up when I ordered my cables so I'm still using my stock GPU and CPU cables but I hope to eventually buy custom ones just to keep everything clean.
I await the day I can shove more than one NVME into the back of a mITX motherboard lol
I added some art pins I've been semi-collecting to the side as well as replaced the tiny little screws with the smallest thumbscrews I could find just so I didn't have to hassle with a screwdriver anymore.
Very silent, thermal paste seems high quality both in 3rd party review standards as well as core temps recorded. It's a whisper even under load.
Very light! I wish there were screws at the top of the sides instead of using only push-pins but if you lay your cables right (or have smaller cables) then it shouldn't be that big of an issue. Screws that hold it together are TINY and very easy to lose. Might consider switching to thumbscrews for most of them in the future but that would kill the otherwise sleek appearance.
The cables are both high-quality enough for use but garbage in appearance and how stiff the cables are to bend.
