Signum 300 Solid

Have fun, create and win with Signum 300 Solid. It's a black box PC case that pleases the eye and is as strong as a tank’s armor at the highest level (hello, we called it "Solid" for a reason). Inside you’ll fit everything you need. You can mount, among other things, a cooling system, a long graphics card and as many as eight (!) fans (!!) – including one Stratus 120 PWM that you get from us for a good start.

Signum 300 Solid

Signum 300 Solid is your personal management center – you can lock everything you need to win inside it, even if that involves meters of cables.

It was designed to impress, and we think it does a pretty good job – the case looks rad and maintains a fresh draft around the PC components. You can easily fit a tall CPU cooler and a 350 mm long graphics card inside. There is also space for eight fans – including one Stratus 120 PWM that we’re throwing in.

Signum 300 Solid can also accommodate two 3.5-inch hard drives with another two 2.5-inch ones (or four small drives instead). That’s enough to make sure your components won’t be crowded like otaku in a queue at a manga and anime convention :)
