The combo savings is eaten up by the cost of the case. Heck, more than the cost of the case. I don't think I would ever pay more than $200 for a case, let alone $850.
Let's see who can build a system with specs as close to this as possible for the least amount. A non-extreme CPU known to OC well along with a single 5970 that will OC almost as well. I bet it can be done for under $2500 easy.
Oh, and I love how they list the heatsink as the first item! You'd think maybe the CPU, video and case? Nah!
Minor details they are, yes. (Yoda voice)
