Behind the massive side panel, there's room for seven optical drives and a removable motherboard tray. Housed below is a separate compartment for the dual hard drive cages and the power supplies. That's right, we said supplies, as in plural. The TJ07 has room for dual side-by-side PSUs and even includes a Y-cable for connecting them both to your motherboard. Think that's over the top? Try hooking up a four-drive RAID array, a couple of optical drives, and some SLI video cards, then get back to us. All these components will require you to break out your Phillips head and tiny screws--no tool-free, snap-on drive rails here.
Our complaints here (aside from the price) are few. There are six fans inside the case, but no fan or vent on the front panel. It probably won't be a problem, but we're airflow traditionalists. Also, you access the hard drive cage by removing the left-side panel, but you must also remove the right-side panel to get to the thumbscrews that hold it in place, a somewhat annoying extra step. Lastly, the front-panel USB/FireWire/audio jacks are hidden behind a small door with a magnetic latch that can be hard to open.
