CONGRATULATIONS! 

!

Thank you for purchasing 
an Obsidian Series

®

 450D 

Mid-Tower PC case.

For performance oriented mid towers, there’s 
no beating the Obsidian Series of cases from 
Corsair. With a trademark black, brushed 
aluminum front fascia and tons of flexibility 
for hardware installation, the Obsidian Series 
does everything you want it to do and looks 
good while doing it.

The 450D is ideal for cooling your high 
performance components. The front panel 
is meshed and filtered right in front of our 
two high-airflow AF140L intake fans which 
have a direct airflow path to your GPU and 
CPU. If you remove the front hard drive cage, 
the front fan mounts can fit up to a 280mm 
radiator, but that’s not all. The top of the case 
is pre-drilled for up to a 360mm radiator as 
well. Not to mention our fantastic tool free 
drive installation, side panel thumbscrews, 
and full side panel window.

The Obsidian 450D is the mid tower you’ve 
been waiting for. It’s finally here.
