The Thor Zone Tetra ITX case is smaller than Sony’s PlayStation 5, but it's designed to accommodate an Nvidia GeForce RTX 5090 and allow gamers to build a high-end gaming PC with a remarkably compact form factor.

Thor Zone officially announced the Tetra ITX case last year, and it's finally available for preorder for prices starting at €259. The smaller Tetra S measures approximately 13.7 x 13.1 x 3.1 inches with a volume of 9 liters, which makes the case smaller than the original Sony PlayStation 5, but slightly larger than the current PS5 Slim (from $499 on Amazon).

The Tetra R is a bit larger at roughly 14.1 x 14.8 x 3.7 inches and a volume of 12.5 liters. In return, it offers space for dedicated graphics cards that are up to 13.9 inches long and 3.1 inches thick, which is enough for many variants of the Nvidia GeForce RTX 5090. In combination with a 2.8-inch CPU cooler, this case should be suitable for high-end builds. That said, the Tetra S is limited to graphics cards that are 12.1 inches long and 2.7 inches thick, and CPU coolers which are up to 2.1 inches tall.

The metal gaming PC case can be opened via a sliding mechanism in order to gain access to the internals from all four sides. It supports ITX motherboards and as well as compact SFX or larger ATX power supplies. Cool air is provided by two 60mm fans (Tetra S) or one 120mm fan (Tetra R). Vents on three sides should ensure that CPU and GPU temperatures are kept in check.

Price and availability

The Thor Zone Tetra ITX case is available for preorder now at the manufacturer's online store, shipping is scheduled to kick off in August. The slightly wider "R" version costs €279, while the slimmer "S" model is priced at €259. The case is available in white, light gray, dark gray, black and green. An optional walnut wood front panel is available for €39, a fitting PCIe riser cable costs €19, and the RGB hub is priced at €29.
