A Closer Look - Inside

To access the interior, simply remove the thumb screws and pull the panels off. The interior is quite spacious, and Thermaltake kept the area around the motherboard clear. You can clearly see where the front-mounted HDD cages on the opposite side are meant to go, alongside a large opening behind the CPU area. Well-placed holes with rubber grommets around the motherboard should allow for a nice and clean build. Interestingly enough, Thermaltake has done away with the Velcro strips, which you will find in enclosures like the S500TG.


The Thermaltake Level 20 RS is actually quite wide, which results in over 30 mm of space to route cables behind the motherboard tray. Here, you will also find a plate to hold two 2.5" drives. Above these is a basic ARGB controller you may attach more generic lighting elements to if you like. Additionally, the PCB comes with a single 3-pin fan header for the rear fan. This device is meant to consolidate the included fans and RGB elements, with a focus on motherboard control. That said, it does come with a built-in button should your setup lack that functionality. The front holds the option to place the Thermaltake Pacific DP100-D5 Plus Distro if you are willing to sacrifice the 3.5" cage in the process. Technically, you could also place fans or a radiator here, but as the glass side panel does not offer any ventilation, Thermaltake does not advertise the possibility.


In the bottom of the front is a single 3.5" cage with two trays. The entire front is meant for cooling, with the two 200 mm intake fans pre-installed out of the box. You may install a radiator of up to 360 mm here, which brings the number of spots for radiators to three.


A small shroud covers the PSU bay on the bottom of the rear. Here, you will find the metal mounting elements for vertical GPU placement, as well as a single 2.5" tray. This brings the maximum number of storage units to six, which is perfectly fine for most users, albeit some may want more considering the overall size of the chassis. The eight expansion slots can be accessed from outside, and the exhaust fan in the top is identical to the intake fan in the front.


Looking at the ceiling, you can see the vast number of mounting holes. As there is plenty of space even above the frame, you can go as far as to install a push/pull configuration of six fans on a 360 mm radiator, for example.


All the cables within the Thermaltake Level 20 RS are of the default variety, so you should run into no surprises when assembling the system. Naturally, they are all sleeved black, but a small cosmetic annoyance is the fact that there is about 1.5 inches of wiring that isn't sleeved at the ends of the USB 2.0 and audio plugs—these are also parts you will see in a finished system.
