It's possible that this would work with homogeneous hardware, but I tried with another LSI-based expander and SATA disks, and had no luck. Perhaps SAS is necessary?

It's connected through a Supermicro cable, CBL-0168L, so it can be attached via an external cable. There's a card needed, CSE-PTJBOD-CB1, that allows the case to run without a motherboard in it. There's no monitoring for the power supplies, but I built one for it; I can provide schematics and suggested part numbers if you're interested. >> We have a SC846E1 at work; it's the 24-disk, 4u version of the 826e1. >> It's working quite nicely as a SATA JBOD enclosure.

This was the best solution we found for the money. The 826 is about $750, while the 846 is $1100 shipped (wiredzone.com). Per disk, the 846 is almost $20 cheaper. If you only care for 12 disks, then one might as well not spend the extra money, but if there's potential for expansion it's a wise investment.
