I designed this extremely compact mATX PC case for my Supermicro server but I thought other people might find interest in it as well. So I am selling the case for anyone that wants it as well.

Shown is the 1U PSU Version. REQUEST either ATX, SFF, FlexATX or 1U PSU version when buying.

The design goal is to make the most compact mATX case that still has 4x PCIe slots for a server without wasted space from extra fan mounts or drive mounts. Modern motherboards use M.2 PCIe SSDs so I didn’t see much point in traditional drive mounts. Although I will include a single 2.5” to PCIe drive mount as can be seen in my photos.

Specs:
106mm H X 287mm L X 262mm W (FlexATX and 1U PSU Version, SFF and ATX Version slightly taller)
4x low-profile PCIe slots
47mm CPU cooler height
247mm GPU length clearance
277mm GPU length clearance without front fan
ATX, SFF, FlexATX, 1U PSU Support

Included:
OwenCase 8L mATX Server Case ASA
Motherboard and PCIe screws
2.5” to PCIe slot bracket
Power button
