The retail case that was speculated about previously was made by Koolance. They no longer make them, leaving the market bare of WC server cases. If I was you, I'd try to find a place where you can purchase a 3U case and take a peek at a 2U case to try to plan a move before buying them. Alternatively, and I don't know why I didn't think of this before, you could go with a 5U case and you would definitely be able to go self contained. A 5U should put you at 10.5" of usable space. All of the PCI cards will easily fit, as well as plenty of room for 2-3 drives AND fit your WC system inside. You'd need to use a small pump (not a big Eheim), and you probably wouldn't have room for a res unless you were really creative. The only modding you would have to do on this:

case is to pull out some drive racks toward the left side (facing the front of it) and you'd be able to fit your rad there. The pump could be mounted next to it between the rad and the CD drives or whatnot. Alternately, the pump can be mounted to the top of the case OVER the motherboard (how is that for looney?). This would take very little modding to do. How does that sound?
