I got an Antec Skeleton case from Newegg.com today.
Case out of the box. Cat in the box:
Empty case, front view:
Empty case, rear view:
Full case, up and running Gentoo Linux of course:
Yes, the computer booted in less than 5 tries. Connectors were the main culprit in lack of bootage.
The documentation that came with this case is absolute crap. I had to google and find a review site to find out how the HDD mount system worked. I pity the noob that tries to assemble one of these from scratch.
Total time for disassembly of the existing Linux box and reassembly in the new case and successful boot: 2.5 hours.
