We have reviewed most Obsidian cases in the past - with a few exceptions. One being the tiny but capable 250D, the smallest chassis in this family of enclosures. This review of the Corsair Obsidian 250D will show whether Corsair managed to shrink its size to the smallest possible denominator without compromising on any of the aspects that make Obsidian enclosures so very appealing.

Get rid of that DVD drive, no Obsidian case should have their sleek looks ruined by ill fitting, outdated tech... :)

I have a 450D and shudder at the thought of it's good looks being ruined by a non flush fitting optical drive.

Great review

here is mine

Great case. I agree with you on most all the point, I was able to get a newegg deal on it and picked it up for $70... but compared to the Lian-Li cases it was cheap!

I like it! It is pretty much just what I am looking for in a mini ITX case. I would have rather seen a slim drive optical bay but what ever. They should make a kit that allows no optical bay, slim optical bay, or 5 1/4" optical bay. Wouldn't seem to be that big of an engineering design.

Page 3 typo: "In the top are two USB 2.0" (should state USB 3.0).

I literally built my new system last night within this case.
Absolutely excellent use of space and I can't think of any way they could have improved upon how well they did it! I highly recommend it.
In it I put an i5-4590, + Corsair H100i, 2 x 4GB Crucial Ballistix Tracer DDR3-1866 (set to red to go with the mobo & gpu), MSI Z97i Gaming AC, Crucial M550 256GB, Seagate 2TB 7200rpm, Corsair RM750W and last but not least ASUS GTX 970 Strix. An absolutely perfect snug fit for everything. Very pleased!:peace:

EDIT: and very very quiet, as both the PSU & GPU fans switch off when cooling isn't necessary and are virtually inaudible when on.

Add a 5 fan controller, 1stly many ITX cases only have fan controls for the CPU and 1 fan. So I am adding the controller and can add 80mm fans without the noise issues 80mm's usually give and 2 better side fans (5 case fans and CPU cooler in total with the 140mm and 2x 120mm as intakes and the 2 80mm's as exhausts).
