I hope this is considered a tip. But 4 those of you seeking rackmounted ATX cases, a new seller on ebay has a large supply of this item for 50 USD apiece. These usually go for 150-200 USD. Be forewarned though, Scope Professionals cards will force you to not use the 5.25" drive bay which sits beneath the PCI section of the motherboard. But there are still 3 x 5.25" bays that sit underneath the RAM/CPU side of the motherboard. Seller says he has a large quantity, as in 100's!!
You know I am so illiterate with computers, I shall try to change this and learn more of linking and shit. Just try rackmount 4U atx, or a version of that search. There are many on the return searches, but not 4 48 USD. It's an incredible steal. They probably bought them w/o the usual shitty power supplies and got a killer wholsale deal.
Only problem is, that you will probably have a hard time finding a portable rack, wich supports the depth. These racks are generally made for server use, and server racks a deeper than musicians racks, because they are not meant for carrying.
Actually these are 21" depth ATX. I already have a DAW w/ SFP/GS3 racked into the Shockrack SKB ATA's. Scope Projects, and Professionals work fine. I just bought one of these and stuck my Conroe and SFP cards into it. A pretty sight to see if you like DSP's.
