Find it on a sale if you can. Its default price here, sometimes up to $159 or so, is worth more than I sometimes see it on sale; on sale, the unit can drop down to $99. At $99, or even $119, you can see the value. At $159, you are getting close enough to better 4U cases that are around $199 Pro: I'm not going to write a pros/cons, just the facts in this category. This is a VERY bare-bones 4U case. There are no reward points here for style. There are no removable/hot-swap trays, there is an old commitment to 5.25" bays you can convert with an IcyDock or similar; the tray layout does not provide for any of the newer methods for routing or cable management, and the spacing is such that you are not going to put any deep mount device in here. While there are numerous 3.5" bays, you really will want to use less than 1/2 of them for both heat and performance concerns. The case, however, is one of the cheaper 4U cases, and if you are looking for a baseline for a simple purpose, like a virtualization header, a Windows server, a firewall or similar, this case is certainly a decent choice. I have had no problems using this as a case for my firewall and VPN software layouts, as well as Windows servers in the past, due to pass-through problems of specific USB security keys that did not like VMWare or XCP's pass-through I was forced to keep on their own.
