The MB082SP won't work in at least some of my Dell computers:
The disk mounting spaces are oriented perpendicularly to the motherboard
and require a right-angle SATA cable. The end of the disks are
recessed on the Icy Dock EZ-Fit Pro Dual 2.5 to 3.5 Bracket (MB082SP),
so even if only one disk is put in the bracket it can't be connected.
My computers are Dell Precision 380. I think the current
T5500 has the same issue.
