Case purchased from craigslist. I saw it for $50 and grabbed it without thinking. The biggest issue was getting the picoPSU to work with the case. Other than that it's WAY TOO BIG. All I have is a mini ITX board, processor, ram, and m.2 ssd in there. Everything fits on my motherboard. The PSU, PCI-E riser, case fan slots, and hard drive slots are totally empty. I only take up 1/3 of the space in the case.
The case didn't have a slot to install the pico psu. I ordered this PCI bracket: http://www.mini-box.com/s.nl/it.A/id.438/.f To get that slot to work I still have to drill a bigger hole in it. The hole it came with was too small for a four pin connector.
Motherboard is great. It controls fan speeds just fine. Read the m.2 ssd without any issues. But for some reason it wouldn't flash my BIOS when I used the hotkey for it during start up. Instead I had to go into the BIOS and press the hotkey from there to flash the bios.....weird.
The case fan is set at ~900 RPM and is silent. CPU fan is about 1300 RPM most of the time and again, silent.
OS is Ubuntu
