Corsair is answering the call for builders who want to assemble a compact PC inside a glass chassis with its new Crystal Series 280X, a small form factor case available with or without RGB lighting.

The 280X looks like a cube from certain angles, though it's actually rectangular in shape, measuring 398mm x 276mm x 351mm. A large tempered glass side panel provides a clear view of the interior, with glass on the front and top of the case as well.
