INSTALLATION GUIDE

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.
