Signum 300 Air

Dress your components in a sturdy armor PC case with enough space to fit eight fans. And prepare the counter for the admiring looks of your besties, because simply no one can keep poker face when passing its glass side part. Especially when you have some PRO components inside – for example, four Stratus 120 PWM fans, which you get from us for a good start. The rest is in your hands, so have fun!

Signum 300 Air

Signum 300 Air is one of our favorite black boxes casescases. It’s laid out well, pleasant to the eye and as strong as the armour on a highest-level tank. Inside, you'll fit everything you need to work, play, and create – and with the tempered glass side you can easily show it off to your friends.

The interior of Signum 300 Air is also impressive. This roomy beast can easily accommodate two 3.5-inch hard drives with another two 2.5-inch ones (or four small drives instead). Not only that, but you can also pack a tall CPU cooler, a 325 mm long graphics card, and as many as eight fans. You get four Stratus 120 PWM fans in the welcome package, so dress warmly before you start the computer ;)
