I tend to use either 1U or 4U servers, depending on the application. But 
I've had good experiences with IBM recently, and a quick look on their 
site shows the x345 with these specs:

•  2U, 2-way server delivers extreme performance and availability for 
demanding applications
•  Up to 2 Intel Xeon processors up to 3.06GHz with 533MHz front-side 
bus speed for outstanding performance
•  Features up to 8GB of DDR memory, 5 PCI (4 PCI-X) slots and up to 6 
hard disk drives for robust expansion
•  Hot-swap redundant cooling, power and hard disk drives for high 
availability
•  Integrated dual Ultra320 SCSI with RAID-1 for data protection

This may not wrap well, but here is the url:

Handles 6 drives; maybe that fits the bill?
