Thermaltake Level 20 GT RGB Plus Full-Tower Chassis Review

A Closer Look – Exterior

First impressions go a long way, and my first impressions are damn this thing is big, and double damn, it’s pretty heavy too. Just moving it around on the table was hard enough work and it can be quite cumbersome to get a good grip on it. I imagine this issue will be compounded once you had heavy hardware such as liquid cooling; you may want to build it where you’re going to leave it! Of course, it’s also a stunning looking beast too, with those curved metal corners somewhat softening the aggressive styling.

The chassis has those gorgeous tempered glass panels on the top, front, and both sides. However, they’re locked up pretty tight, literally. You need an actual key that comes in the box to unlock this one and the right side panel window. This stops anyone just opening up your case at LAN, or even just keeps your kids’ fingers out.

I/O

The top of the side panel swells up into a large top panel, where you’ll find the I/O section resting in a cutaway to the frame. Well, half of it, just the power and audio here, as there’s a similar panel on the right side too.

Just like the left side, you’ll find another gorgeous tempered glass window and key lock here. This does mean your cable routing will need to be bang on, as it’ll all be very much exposed. There’s some tint to the window, but it’s hardly blacked out either.

On the right side of the top panel, you’ll find the second part of the I/O. There are two USB 2.0, two USB 3.0, and a Type-C connector.

More tempered glass on the front panel, although this one doesn’t open, you can remove the entire panel to mount cooling hardware if needed.

The top panel follows the same design, with more glass matching the front panel design. Both of these panels are gapped at the sides though, allowing loads of airflow through to any coolers mounted behind them.

Wide as Wide Can Be

Around the back, you really get a sense of just how wide this chassis is.

There’s a 120/140mm fan mount towards the top, which comes with an RGB 140mm fan pre-installed.

Below that, you’ll find eight expansion slots, each with a reusable metal cover.

There’s a PSU mount at the base too. Of course, the chassis is super wide, and there’s plenty of extra ventilation back here too; big graphics cards shouldn’t be an issue then.
