Great case but if you mount an 240/280mm AIO rad in the front, you will inevitably shorten the life of the pump due to the fact the air at the top of the cooling system is now effectively in the pump/cpu housing. A top mounted 140mm single fan&rad aio at the top is my best recommendation. Additionally if you are mounting fans in the front of the case, make sure the fans are physically inside rather than outside the case housing. Otherwise the gap between the fan & the front shield is too small, strangling the case for airflow. I have since purchased the P300A front panel which is mesh, instead of solid metal, allowing substantial airflow for my sandwiched push pull 240mm front mount AIO, allowing it to function perfectly.

Really pleased with this Mid tower gaming case. It was a good price and looks really sleek, I especially like the clear side panel!

Excellent case for the price, very good build quality and cable routing is easy. Limited mounting points for a 240 AIO is the only real drawback

This is a great case. It looks amazing, has space for 4 fans (two hidden in the front), RGB, a nice clear side panel, and a nice design. It also has many drive bays - two 5.25" bays, and two 2.5" bays (though you have the buy the 2nd 2.5 inch bay separately, which is really my only gripe). It's nicely designed with cable management holes and good cooling. Would definitely recommend.

Solid budget case!

I'm quite pleased with my experience with CCL Computers. My case was priced quite competitively and the delivery was very prompt also. I would order from CCL again.

Bought this case based on other reviews and it seems to be the best for its price range. Really good case and easy to build in even for begineers (such as myself). Only issue I had was that one of the mobo stand off ended up going into infinity spin, which was not that much of an issue but wouldn't expect it to occur straight away.

Plenty space for airflow and cable management on a budget

Nice tower ,easy cable management

I think this is a great case I loved building in it and I love the glass side panel and it comes with built in velcro straps. The only issue is that some wires in the velcro strap shouldn't be there as they aren't long enough to go through the holes they were intending. However all the wires managed to be wired to the motherboard
