The Thermaltake level 20 premium chassis line was designed to celebrate the company's twentieth anniversary. And based on our experience with the great and bold Level 20 GT, we can say that the company's experience shines mainly, like the light of the RGB fans in the box through its four panels of tempered glass. This high-end case has an elegant appearance and almost all the features that an enthusiastic builder could ask for. We just wish the company included a vertical cable to vertically mount the graphics card (especially given the $ 289 MSRP) and that the dust filters were easier to remove and clean.
- Superb design
- Build quality  USB 3.1 Gen 2 Type-C
- Vertical GPU
- Tempered glass panels 5 mm thick on four sides
- RGB fans of 200/140 mm included
- EATX plates holes for cable management of the cover
- Vertical cable not included
- Badly designed dust filters
Verdict  The Thermaltake Level 20 GT RGB is an excellent chassis that looks as good as it works. But the price of $ 289 (£ 227.13) will probably be the deciding factor for most people who consider this case.
Leaving aside the performance and the options, the main point of sale of this chassis is its sophisticated style and its unique appearance. Despite the fact that appearances are subjective, we believe it is safe to say that the design of the Level 20 GT RGB will be the decisive factor, regardless of the price. The Level 20 GT RGB incorporates the latest innovations and features of the company, such as SyncALL, Tt RGB Plus Ecosystem, Razer Chroma lighting support, rotating PCI-E slots and more. Although most people will not use many of these integrated functions, they are certainly a welcome addition.

Made of steel, plastic and tempered glass, the thermal absorption level 20 GT RGB is quite large with 22.9 x 11.6 x 23.3 inches (580 x 294 x 592 mm) and weighs 44.3 pounds (20.1 kg).
The entire front panel and most of the top panel are tempered glass paired with a plastic frame, with an air space on both sides. Just below both panels you will find built-in fan filters and mounting locations for up to three 120/140 mm fans or two 200 mm fans.
On the top edge of the top panel there are two USB 2.0 ports, two USB 3.0 ports and a single USB 3.1 Gen 2 Type-C header on the right side. The headphone and microphone jacks, the power and reset buttons and the hard drive activity light are on the left side.
The full-coverage tempered glass side panels are held in place by a locking mechanism.
On the back of the chassis there are eight standard slots for expansion cards, an opening for a power supply mounted on the bottom. and a mounting location of the exhaust fan that supports 120 mm and 140 mm fans.
A large plastic mesh filter that covers most of the bottom of the chassis is removable from the back. The four rubber-covered round feet keep the case more than 0.5 inches (13 mm) from the ground.
The fan filtration system in the Level 20 GT RGB is effective, but it is a serious pain in the back when the time comes for cleaning. For the most part, cleaning and maintenance are best done with the entire panel removed.
Only after removing the upper and front panels of the chassis can you access the four screws (per panel) that hold the tempered glass panels attached to the plastic frame. With the TG panels out of the way, you now have the ability to wash these fan filters. Sure, you can wash the top and front panels with the glass placed, but, in this scenario, there is no way to dry the front of the panel (which is actually where the dust tends to accumulate), which generates unsightly water spots and stripes. The large removable filter on the underside of the chassis can slide out more easily for cleaning, but you will still need access to the back of your case to do so, which means that you will probably have to move your platform to gain access. The bottom filter should slide out from the front, especially in such a large case.
