Goal was an inexpensive, low power, headless backup/NAS box that could fit 2 or 3 hard drives. I'm fairly satisfied I got what I wanted...
- for being a small box it was fairly easy to work with, the power supply comes out easily and gives extra space
- clearance between the CPU cooler and power supply is fairly tight but manageable
- clearance between the 3.5" external/internal bay and the memory is extremely tight but just barely works (no memory with fancy heat sinks in this box!)
- The holes in the 3.5" bay don't quite match up for thicker hard drives, I had to move the holes up (with a file!) about 1/8th" to fit (note: I was using an older hard drive, and newer ones tend to be a bit thinner and might fit ok)
