E-ATX Cube Chassis

Clearly Gorgeous with Tempered Glass Panels

The front, top and side panels are all built from our ultra-durable 4mm tempered glass. This means the panels are more resistant to dust and scratches than acrylic and provide a clearer view of internal components.

Chamber Design

The Level 20 XT carries over the innovations of some of our earlier cube case designs by splitting the chassis into two chambers. The chamber houses the motherboard tray GPU and other PCI-E cards, while the lower chamber houses the power supply, storage devices and cooling elements.

Advanced Ventilation

Level 20 XT is preinstalled with one 140mm rear fan. Level 20 XT enables users to build a complete high-end system with ample room for up to two front 200mm fans and is fully compatible with 420mm, 360mm, 280mm, 240mm, 140mm and 120mm radiators. Removable top magnetic fan filter, front fan filter, and bottom filter provide excellent reduction against dust, and better airflow.

Small Footprint with Big Possibilities

The Level 20 VT is all about big things coming in small packages. The VT supports M-ATX motherboards, as well as CPU coolers up to 185mm in height, VGA lengths up to 350mm and PSU sizes up to 200mm in length. It also supports up to two 240mm radiators side-by-side in the top panel, or one 280mm at the top or along the side. Meaning you can fit plenty of top-end hardware in this little case.

Chamber Concept

The Level 20 VT is optimized for space management. It's divided into two main chambers: the upper chamber is made to house the motherboard and PCI-E components, while the lower one is made for the PSU and drive bays. Thanks to the removable 2.5"/3.5" drive device racks, there is plenty of flexibility to fit larger components or build a custom liquid cooling loop.
