To gain access to the inside of the Level 10 you first have to remove the right side panel by first unlocking it, loosening the thumb screws, sliding the panel to the rear, and then tipping it out.
With the panel off you have access to the hard drive back plane area and the locking tabs for each of the compartments.
Looking closer at the backplane for the hard drive we can see the combined power and SATA connector. The Level 10 only comes with two of these connectors. The end user is to provide cabling for the remaining 6 drives. Thermaltake store has these on their website for $9.99. To the right is a switch that is pressed when you have a hard drive in the slot. This switch turns on an LED that tells you have a drive in that slot.
To lock the hard drive cages, as well as the 5.25″ drive cage, there is locking bar that has to be pressed downward to unlock the cages. The bar is held in the locked position by spring pressure. It can be removed completely if you like, but there is no other way of keeping the drives in place.
There is plenty of room for hiding wires; there is a trough in the very bottom that has the stock wiring run in it and there is room to run more.
With the Level 10 opened up we can start to get a look at the inside. The Level 10 does come with two fans for in the main chassis. The first is a 140mm to help bring air into the case for the video cards and the second is a 120mm to help pull the air out.
By removing four thumb screws the motherboard tray can be removed. As you can see the fans have insanely long power cords (40 inches (1 meter) to be exact), plus a 12-inch (30 cm) 3-pin fan to 4-pin molex connector. There should be no issues getting the fans to a fan controller if you chose to use one.
The motherboard tray has a plastic insulator/cheat sheet. It is very nicely made and has a key screen printed on it to show what mounting holes are needed for what motherboard type. It can be removed if you like but it doesn’t hurt anything to be there.
The inside of the motherboard bay cover is what will limit you CPU cooler choices. There is a 150mm height cap. As you will see later I was able to get the 158mm tall Noctua NH-U12P cooler in the Level 10, but just barely.
