OBSIDIAN SERIES 250D Mini ITX PC CASE
250D

CONGRATULATIONS!
!
If you want to build a Mini ITX system
without compromising expansion,
flexibility, or performance, the Obsidian
Series 250D is your answer. Though it’s
small on the outside, the 250D has room
for standard components like a full-size
5.25" optical drive, a full-length GPU, a
240mm radiator, and even a full-size
ATX power supply.
The sleek, aluminum front fascia provides
the striking yet subtle design that
Obsidian Series cases are known for, and
a top window gives you a close-up view
of your high-performance components.
The 250D is a great choice if you want
full size performance in a small space.
Thank you for purchasing
an Obsidian Series® 250D
Mini ITX PC case.
