At the backside of the chassis we notice the big gaping hole in the motherboard tray. This actually is a CPU back-plate cutout which allows you to remove and install a new CPU cooler much easier. Typically you'd need to take out the motherboard to install a new cooler, now you can access it from both sides without the unpleasant experience of removing a motherboard from the chassis. Very popular with many chassis manufacturers these days alright. Also you can spot rubber inlays for cable feed through on the MB tray for easy routing and hiding cables.
There is space for cable routing here, not dramatic heaps of it but in-between the motherboard tray and backside panel a good 2 cm. That's okay.
At the top side we can see a huge mesh, you can mount 2x120/140mm fans, 1x180mm fan or even a 200mm fan. So that is plenty of options should you want top go with a liquid cooling kit.
You'll get 7 PCI slots to play around with so in theory you can house up-to three graphics cards in here, two I'd recommend as maximum as space wise you can run into problems.
At the bottom you can mount the PSU and if you'd like to do that an additional fan; a 120/140mm fan would mount quite well there. Unfortunately there are no rubber pads where the PSU could rest on.
Cougar Challenger review In this review we have a peek at the Cougar Challenger, a mid-tower chassis that is loaded with options, and hey .. it's priced quite competitive as well. It's different alright. The CHALLENGER mid-tower case is particularly targeting gamers demanding for huge upgradeability capacity, best airflow and optimized ventilation characteristics.
