Had some older unused mATX small size main boards, fully equipped. Before recycling, I saw a need of small linux based server. The original Midi Tower chassis with 400W power supply was quite some big piece of furniture for this equipment. Have not found anything interesting, simple and small enough, so decide to make my own.
I am not sure, if this will be universal for all mATX board, just make it for mine with some small reserves. The size of the board is 19.0cm x 17.4cm, GA-H110M-S2V, picture attached. So check first your dimensions. The case can fit up to two PCI-e small factor cards, I have an extra network adapter there.
You will most probably need to drill some holes for buttons or LEDs, if you need them. Or make small redesign. I can share Fusion360 source, but it was a kind of fast design over weekend.
Board is powered by mini-ITX power supply Inter-Tech MINI-ITX PSU 160W with external AC/DC adapter. For the linux usage the power consumption of this set does not go higher than 30W, so 60W 12V adapter is good enough. For Windows in basic “office” works it takes about 50W max, so you would need something bigger. Sure this is not mentioned to be equipped with some external graphic adapter or such. I am running on 6th gen Pentium Gold with Intel HD Graphics 630 there.
You can print in one piece with Prusa MK2/3/4 type printers, included the gcodes and PrusaSlicer project with some supports. Or to avoid supports on the front/back side with connectors, you can print the front panel separately and glue it later. But to glue these parts from PETG is not so easy.
Printed with PETG, 0.2mm.
You will need couple of screws to fix the board, lid and SSD drive. I used the some screws as comes with standard PC chassis for both. So in fact those I removed from the original case.
This is not anything extra durable. Should just basically protect the main board from the impact from outside!
EDIT: Uploaded slightly modified parts with small improvements, you can search for 10 differences in the photos ;-)
Uploaded remix with bigger dimensions to accommodate bigger boards.
