Minimalistic, compact and fully equipped computer case for a mini-ITX motherboard. Specifically made for Asus H81T, but should work fine for many others as long as using external powerbrick or very compact PSU - Asus H81T has built in power socket that works fine with most Dell laptop chargers - no modification needed.
Thoroughly ventilated - NO CASE FAN NEEDED.
With Intel stock CPU fan running in silent mode, with CPU on full load at 3.2Ghz, the computer is still almost dead silent and CPU temp rarely go above 40°C - idle temperature is around 30°C
Has two slots for 2.5" drives (SSD or HDD). For extra safety you can add a dab of hot glue or double-sided tape under the drive(s) to secure them if you plan to move the computer around a lot.
Standardized motherboard mounting holes fits all mini-ITX boards. Depending on your print settings and screws used, you might want to tap or drill up the mounting holes slightly. There is a big safety margin between the disks and motherboard, if you have an isolation layer to avoid shorts or plan to fasten disk(s) with hot glue, you can file/cut the mounts down several mm to get a drop of the entire motherboard.
Snow flake hole centered directly on top of CPU fan. Intel Core i5 and Pentium stock coolers tested and fits height-wise, probably others too.
Has a socket for a standard PC power or reset switch that can be salvaged from almost any old computer. Placed near the right rear corner. Mostly out of sight, yet easy to reach.
Has a minimal hole for power LED in front, drill this up from the inside if too small when printed. Fasten LED with hot glue if needed.
The lid part slides on from above, using guide rails. There is no locking mechanism for the lid, so grabbing hold of the bottom part is recommended if you want to move the computer around. On the other hand, it's very easy to remove the top for cleaning, troubleshooting or upgrading the hardware.
If you want a tighter fit for the guide rails, simply wrap some tape around them until the fit is as you want it.
The case in the photos were printed in PLA, then sanded and spray painted with acrylic clear coat.
