The full tower Obsidian case for great-looking high performance PCs

The Obsidian Series 750D full tower PC case combines generous expansion flexibility, room for advanced cooling options, and an interior that's optimized for fast and easy builds and upgrades. It has a clean, elegant exterior that dispenses with arbitrary plastic add-ons in exchange for the beauty of brushed aluminum and solid steel. This rigid, rugged exterior surrounds a frame that has ample room for high-performance components and the sophisticated cooling you'll need if you're going to push those components to their limits. And, it incorporates a host of clever system builder-focused features, because building a system should be straightforward, trouble-free, and even fun.

Experience: 60 Days


Huge. Easy cable management.
It's huge :P
I wanted a nice large case that would be easy to work in and not limit any future parts.

Experience: 1 Days

Lots of room
Easy install
Good airflow
I don't like the magnetic top filter.
I got this to replace my p182. Thumbscrews for pci cards make it easy to replace components.

Experience: 30 Days

Lots of space,
well built,
everything is easy to access,
good airflow.
The top filter is fragile. My cat destroyed it.
I had to remove the rubber washers from the top intake; Corsair H90's included screws where to short without removing the washers.
The power button feels cheap and is hard to push properly.
I like it, but it's big and it's heavy. There's lots of storage for hard drives and SSDs and there is enough space behind the back-plate to hide all cables. Dust filters keep your computer dust-free. There's a fan mount on the bottom, so the power supply can get fresh air intake from under the tower. No more screws falling inside a reversed power supply! Lots of thumb screws included. The 5.25", 3.5" and 2.5" bays doesn't requires screws. Sleek design, but I would like to hide my bluray drive.

case has ton's of storage and is massave
This case is huge! with all the dive bays and all the options it comes with you can do what ever you want to with it. from a simple pc build to full out water cooled system. lot's of room for air.

Large Case, lots of room for expansion, excellent airflow due to cable management options, quiet
Large Case
So much better than my old case that I noticed a 5C drop  pretty much immediately, and if I want it cooler, all I have to do is drop  open the front panel. Almost infinitely quieter than my old case with the 140mm fans as well. It was an excellent purchase, and I've already enjoyed adding an SSD and a couple additional 2.5" drives to what I already had installed in the old system. Oh and don't let the specs fool you, each of the 6 x 3.5" HDD slots is also capable of handling either a 2.5" or 3.5" drive, there are then 4 additional 2.5" SSD bays.

Lots of space, nice cutout for the cpu, nice ssd location placing. Holds pretty much any radiator
Gromets for cables are weak( removed to easily), ssd are loose in the racks, unless screwed in. Power button seems fragile
Great overall case with tons of space. Very silent even with 2 additionnal 140MM fans. But as mentionned in the cons, the gromets are always moving when passing cables through, you need to hold them. SSD's need to be screwed in so they don't move, which is not completly screwless. Still a great purchase!!

lots space
got it i would recommend this for space lover summer coming so testing it out if it goes hot

Experience: 1 Years


sleek and simplistic design. lots of room for anything you want to install.
the latches for the front fan cover are weak, front drive bays look really bad if you want to put anything in there, bottom dust filters vibrate.
when i bought this case the front fan cover panel latches were broken because the panel is not secured well enough for shipping IMO, had to RMA because of that and the bezel was broken as well. my replacement had the same issue with one of the latches being broken. but i was able to fix it, so i decided to cut my loses.
you can see when im talking about here

over all the case is a good case

Experience: 3 Years


cheap plastic door catches.
overall ok. but for the price they could improve the plastic door catches

Experience: 4 Days


Easy to use, great design and very well ventilated!
None so far
Plenty of space for any heatsink or graphics card!
