I own one; it's a much older version of what they sell now, as I bought mine in 2004. Judging by the pics on their website, it hasn't really changed much. It is built like a tank; all steel. It is not the most mod-friendly or user-friendly case out there. The drive cage/fan area is pretty large, but not well laid out, IMO. See pic below.
The fans that come with the case are data-center grade hovercraft type fans; you will need to replace them if you're even thinking about using this as a pedestal server under your desk. The nice thing about it is that it's very flexbile. Bought new, it can be purchased in many different configurations; backplane/hot swap cages/ATX PS/redundant PS, but it is essentially an "old style case". Note the full-length card support brackets and screw on snap-type drive rails. I do, however, like the fact that it has a 120mm rear/exhaust fan. That makes your silencing the case job MUCH easier. The typical 4U consumer type case comes with two 80mm fans. By the time you actually find quiet 80mm fans, you also find they don't move much air at all.
If it wouldn't cost more to ship than it's worth, I'd offer to sell you mine as I'm not using it and probably never will since I already have 3 other rack mount case and an old Antec P80 for if I ever do an under-the-desk system again. I bought the base case. No backplane, no hot swap cages and I think I already Dremeled out the front grill in the drive cage...and IIRC, all my fans are dead. I did get my usage out of it. LOL!
