Well laid out.

The only real issues I have with this is that a 3Ware RAID card won't fit very easily if you wish to have the CD drive plugged in.

First time purchasing Supermicro products, we usually buy Tyan.

Doesn't come with a heat sink.

Simple elegant case layout, Serverworks chipset works well with BSD OSs.

No manuals whatsoever, you need to buy a heatsink, and no Debian SATA support.
