The Thermaltake Level 20 HT is quite the unique chassis. Where many brands try to maximize the use of space and throw around key metrics like performance per liters, the Level 20 series throws that out the window and gives the user the most uncompromising approach to custom liquid cooling possible. The HT variant is essentially as tall as a classic full-tower chassis, but twice as wide. This massive footprint naturally makes for quite the heavy case in a normal scenario. However, Thermaltake has also opted for 4 mm thick glass panels on four sides of the enclosure, which further adds to the heft and is the reason why it breaks the 20 kg barrier when empty—a value most other cases approach when filled and up and running.

All this should be fairly obvious for those looking to purchase the chassis. Thus, focusing on the details, the main use case for the Level 20 HT is certainly the ability to install your own custom liquid cooling solution with up to two radiators and two pumps/reservoirs. This means your video sub-system could have its own loop, while the CPU enjoys its own liquid cooling solution as well. Even with such a setup, things will never feel crowded inside the Level 20 HT.

Thanks to the removable motherboard tray, the tool-less HDD cages, and all-around accessibility, assembly is refreshingly easy as you don't have to keep handling the extreme dimensions of the enclosure itself for most of it. Clocking in at $200 with its two fans, the Level 20 HT could almost be considered affordable and certainly adequately priced. You do get a lot of chassis for the price even if the interior may be a little simple compared to some enclosures out there. The material mix and detailed exterior design touches more than make up for it.
