Mini ITX without Compromise

If you want to build a Mini ITX system without sacrificing 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.

For high performance in a small size

The small size of the 250D makes it great for dorm rooms, desktops, bookcases, or anywhere else space is an issue.

Black anodized brushed aluminum fascia

The front panel has an elegant look that befits the high-performance system you want to build. It’s durable and resistant to scratches and fingerprints.

Fits full-size components

Many Mini ITX PC cases impose strict limitations that can make it difficult to build a well-cooled, high performance PC. The 250D has a highly efficient interior design that allows for a 5.25” optical drive, a full-length graphics card, and a full-size ATX power supply. There’s even mounting points for a 240mm radiator for advanced CPU cooling.

Keeps your GPU cool

The interior is arranged so that the included 140mm front intake fan draws cool air directly over your GPU. This can help with reliability and give you extra GPU overclocking headroom.

Front panel USB 3.0 and audio I/O

You want to build a system that’s not only fast, but easy to work with. Up-front USB 3.0 and audio connectors let you quickly attach high-speed storage devices and headsets.

Windowed top panel

The joy of building your own system isn’t just about utility. The clear acrylic window lets you show off your work.
