Ended up with the Carbide 500R, nice case and quite roomy. Thanks for that recommendation! Building into it was easy as pie and now she's (kinda) running 5 3TB drives and a 320Gb boot drive (no need for SSD and the 320 was a recycled part). However in the process of set up etc. I quickly found out the Antec Earthwatts 500 watt PSU was weak, it kind of well...died. Probably going to pick up a Corsair CX750 semi modular on the way home tonight. Also going to hunt down in my collection an IDE HDD that I can use as the boot drive instead of the SATA one and then replace the 320Gb with another 3TB drive and have the whole HDD array lined up perfectly on the SATA controller.
Now to seriously start planning the rebuild of my primary gaming rig...the old i7 950 is showing it's age
