A Closer Look - Inside

To access the interior, you don't need any tools at all. Thermaltake has done an excellent job in engineering the panel so that the only locking mechanisms are the two big knobs on the side panels. These swing open due to the hinges and may be removed completely to allow for unobstructed assembly. I actually removed all four glass panels for this purpose as it also reduces the overall weight of the Level 20 HT considerably.


Upon closer inspection, the main compartment is actually quite simple. It mainly consists of two plates, one of which is for the motherboard, while the other is an extension to that with additional grommet-covered openings. This smaller bit may be taken off if you choose to install liquid cooling or fans vertically underneath the motherboard with the bracket found on the floor of the chassis. In the rear, you will notice that the opening for the CPU cooler area is actually a bit larger than usual. The other apparent element consists of the hard-drive cages for four 2.5 or 3.5" drives in this smaller rear compartment.


Taking a peek at the sides of the Level 20 HT, it becomes clear that the main compartment is much larger than the rear to allow for liquid-cooling elements, for example. Thermaltake has designed the case to allow you to install quite the elaborate liquid-cooling setup in full view of those curious enough to take a closer look.


In the smaller compartment is a bracket for fans or liquid cooling which will fit three 120 mm or two 140 mm fans, or a respective 360/280 mm radiator. The HDD cages each hold two drives and may be moved horizontally to best fit your needs. One could also switch the positions with the fan bracket or even install more HDD cages if you can get a hold of more somewhere.


In the rear compartment, looking up, you can clearly see the 140 mm fan on the left, while the right spot holds the bracket for the PSU itself. While it looks like you could place the PSU elsewhere, your choices are pretty much limited to the fan-mounting positions. On the floor, the opening is specifically for ventilation only as it is not intended to hold any active cooling.


In the main area of the Level 20 HT, the ceiling looks very much like the back of a traditional case with eight expansion slots protected by black covers which are held in place by thumb screws alongside the second aforementioned 140 mm fan. On the floor is another bracket for three fans or a 360 mm radiator. On top of that, Thermaltake has included two plates for pump and reservoirs and a single 2.5" tray, which brings the total storage to a pretty useful five within the enclosure.


All the cables within the Level 20 HT are of the default variety and sleeved black. They are long enough to easily connect to the right spots with the exception of the fan leads. Equipped with 3-pin headers, things are pretty tight when it comes to plugging them into the right ports. Sure, one could use a random header on the motherboard, but the board will treat the RPM differently if you end up plugging a fan into the pump header.
