OK, I'll make a note of that.

BTW Interesting that Paul's sheet shows elephant as a 2U. I might have =
made a mistake.
Oh, and on the bears, these are their specs:
X7DWU mobo
2 x X5272 CPUs (3.4GHhz, 2 core)
4 GB mem
AOC-USAS-L4I SAS card (LSI 1068E chip) - RAID 1,0,10 only; should
support SATA as well
SAS/SATA backplane
Intel 82575EB onboard
DVD/CDRW Combo
2 PCI-E x8 slots in risers
Best,
George
