- Fits a mini-itx motherboard
- Compatible with your power supply
- Fairly durable
Probably most any mini-itx case would work fine as long as it has a spot to mount the power supply, but I narrowed my search to cases designed specificaly for car PC's.
The case that stands out to me to be the best choice is from a company called Mo-Co-So. The 4th gen Mini ITX case is compatible with popular DC-DC power supplies (specifically the M2-ATX) and has built in RCA audio output jacks located away from the power supply to help reduce electricaly interference. It can take 1 slimDVD drive and 1 2.5" HD. I had considered also the VoomPC-2 case, however, I've read that the RCA output jacks are too close to the power supply and cause too much electrical interference. And that's actually in the product description!
