A Closer Look - Outside

It is already quite apparent that this case is large, but having it on the table really has it sink in. In terms of general size, you can consider the Level 20 HT to have the volume of essentially two classic full-tower enclosures. Thermaltake opted for a mix of four thick, slightly tinted glass panel, lots of steel, and some plastic elements with silver accents for the "Snow" edition of the chassis.


Looking at it from the front, the glass panel is framed in black on the top and bottom, with two air vents on the sides of the enclosure. There are no visible mounting mechanisms, but you may pop the glass panel out with the press of a button on top of the case. Interestingly enough, there is a slight gap between the glass and the rest of the frame on both sides, which seems to be intended. The only panel that does not sport any glass can be found on the rear. Instead, Thermaltake opted for steel with the ability to install two 120 mm fans in the center. This opening is protected by a black metal mesh cover which is held in place by magnets.


Both sides of the Level 20 HT consist of glass as well and are kept shut by a locking knob. As you can see, these allow you to view both the larger front compartment and the more compact rear area of the enclosure.


In the top, a fairly thick top cover not only houses the I/O in two sets consisting of four USB ports, two of which are USB 3.0, but also a fully fledged USB-C connector and the usual audio plugs. The power LED in form of a square has been placed around the power button itself.


The fourth glass panel can be found on top of the chassis and may be removed by pushing it down. Once freed, you may also remove the two strips on either side if you are so inclined.


Thermaltake has designed the chassis with a 90° rotated motherboard tray, so all the connections face upward. This trend continues in the secondary compartment with the PSU bay facing upward as well. Two identical 140 mm fans in the ceiling help pull hot air out of the system. It is thanks to this layout that the Level 20 HT can sport three full-size glass panels all around the sides.


On the underside, you will find two openings which are both protected by magnetic dust filters. The larger one is intended for liquid cooling or additional fans as we will see later on, but the other is purely for passive ventilation, it seems.
