Product Information
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 350 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 ;)
A cold wind blows...
PC hardware likes it when a cold wind blows through the chassis every once in a while. This way nothing overheats, and no unexpected reboots kick you out of the game – even when you’re playing with graphics at the highest settings. Just like you, we also like to click away without worrying that the screen might turn blue any second. That is why we’ve put as many fan mounts in Signum 300 Air as we possibly could. To put it simply – we've handled it cool, so your components can breathe.
Stratus 120 PWM fans
Signum 300 Air chassis can accommodate eight fans. For a start we’ve thrown in four of our Stratus 120 PWM ARGB, which we’ve developed in cooperation with Synergy Cooling. These are quiet, efficient, and durable fans with ARGB lighting, equipped with long-life fluid dynamic bearings. You can control them with a PWM signal, which means that extremely low speeds are achievable for a pleasant silence. You will hear nothing but our own mouse clicks and the rustle of curtains moving in your home office ;)
Tempered glass window side
Signum 300 Air has nothing to hide. We’ve made one window side from tempered glass – it’s durable and gives you a good view on your components. It also looks out of this world, either with ARGB lighting inside, or with a clean all-black build that will broadcast your no-RGB allegiance.
Can you wrap your chassis around it? O.O
Behind every virtual race won or every video edited, there are top-tier components that made it possible. Lots of top components. That’s why we’ve made room for more. You no longer have to choose between a better graphics card and a more extensive cooling system – you can fit both.
