I pre-ordered the DAN Cases A4-SFX on Kickstarter a while back, and it just happened to finally ship while we were putting together systems for this year's builds for Dreamhack Austin. We packed a fair amount of power into it's tiny enclosure and have been pretty pleased with the resulting performance.
Something we kept an eye on in addition to CPU and GPU load (which you can see in the side bar), was the M.2 drive. For mITX systems, you often install the drive on the underside of the motherboard where airflow can be limited. However, with the A4-SFX, the airflow was sufficient to keep the M.2 at a cool 55C under load.
You can watch the livestream archive if you're curious to watch the build came together and check below to see a few benchmark results.
