On the inside, you can see the removable hard drive cage that supports up to 7 devices. The Element uses an interesting system for easy HDD removal and installation. They have included proprietary screws that attach to the side mounting holes on a hard drive, which then slides easily into place in the cage. A plastic catch at the back of the cage holds them firmly in their spot. This makes it easy to swap drives in and out of the cage, without actually having to remove the cage. The cage also orients the SATA and power connectors to the back, giving you easy access to run cables behind the motherboard tray. Thermaltake has engineered in a nice cable management system behind the motherboard tray to run the majority of your cabling, helping reduce case clutter and keep air moving. We had no real problems running most of our cabling this way and we applaud Thermaltake for including it in a mid-range case.
You can see here that the power supply actually rest under a small divider that helps segregate the main chamber. Power supplies can be oriented however you wish, with the exhaust fan pulling from below the case or from the main chamber above. The divider is easily removed and has an ample amount of access holes for running power cables to your mainboard and GPU plugs. There is also a small adjustable tab that sits firmly against the power supply to help stabilize it in place. All the edges are rolled on the divider, which is a nice bonus to help reduce accidental finger slashes.
The backside of the motherboard tray reveals the small built-in snaps that can be used to route your cables effectively. These snaps are easy to open and hold quite a few cables, even under pressure. There are two small access holes towards the lower half of the motherboard tray for routing your SATA cables, as well as one big one for cabling by the power supply. There is also a small hole on the rear half of the tray to allow for your +12V CPU connector, although you will probably need an extender or long power supply cables to use it. The motherboard tray itself features pre-tapped stand-off holes for both ATX and MicroATX and there is even a small guide stamped into the steel back plate, making setup a breeze.
