I've had this case for over 4 years now - Currently building a new PC and not surprised to see it's still in the market. My only reason for looking for a new case is I’ve since moved to a new house and my PC is now on show and I’d quite like a windowed case for my new build.
With regards to other comments, I’ve had no issues with my side panels sitting completely flush even after moving house and taking the side off countless times. I’ve personally found the build quality to be excellent, even at 4 years old.

Brilliant under £50 case

I've had this case a few months now and love it. It's neat, everything slots in nicely, and it looks low-key.

Inside I have managed to fit:

* Asus Nvidia GTX 660 graphics card, which is 71mm. DO NOT put anything larger than this in as it was already a bit of a wiggle to get all the cables etc around with mine.
* MSI Z77A-G43 Intel Z77, fits absolutely fine and fits on the pre-placed slots so no need to fiddle around.
* Solid-state harddrive, slots happily at the top of the drives cage with no fuss and no need for extra parts. There is an additional space for an SSD at the bottom of the case frame.
* Secondary harddrive, fits in one of the 3 3.5" drive slots.
* DVD drive, slots in no problem.
* Power supply, seated at the bottom rear of the case.

There are a few small issues:
* Side panels do not sit completely flush. This means that sliding one of them off can be a slight irritant and if you're obsessive about everything being perfectly aligned then perhaps spend more money. However this isn't a big problem and they still screw in place with easy-remove screws.
* No dust filters except for primary bottom fan. My flat is really dusty so this is sad.

Otherwise I am very happy with this case and think it's excellent for the money. The build quality is a tiny bit slack - mine arrived with a few small scratches and the side panels aren't quite flush, but all the connection slots/holes are completely correct. I've never had a problem with heating when playing games at their highest resolution (eg Skyrim, AC3, Civ V), nothing rattles around, and it's easy to install new bits and pieces.

I happily recommend this as an excellent sub-


Brilliant for the cost.

This case is a pure gem in the sub-

Amazing case under £50

Well here goes my first ever review with OCUK.

I've managed to snatch the very last case from Overclockers last week. The delivery was fast and unexpected. I've ordered around 5PM on a Friday thinking it will arrive on Tuesday the following week as it stated on the order page that any orders placed after 4:30PM on Friday will be delivered by Tuesday. To my surprise it actually arrived on Monday.

The case quality is amazing with a matte black finish. The tool less 2.5" harddisk bay was going side ways compared to conventional case which gave more space for the graphics card and allowed true back-wiring for the harddisks.

There are two 120mm fans already attched to the case.

Granted I've never ever purchased any computer case that cost more than

Bargain Beauty

Nicely designed case at a reasonable price. Replaced my antique Lian Li PC-7 with this and temps are noticeably lower. I'm only using 3 of the 4 fan mounts (bottom fan not in place) but TBH its overkill even with 3 fans. The two installed would cope with most setups.

Spot on, building in this case was a breeze and it looks more than it costs!
