Several hardware generations back, my old 4x160GB raid5 had two drives on the bottom of the case, held on by screws going through holes I drilled in the outer wall of the case.

These days I managed to snag a deal on a Supermicro 846. I'm still settling into it, the main thing that concerns me is being able to suck enough air through the drive bays without making a lot of noise. My previous incarnation used some iStar toolless drive bays. I've learned to appreciate hot-swap bays, mainly for only having to do the cabling once.
