Great case - Highly recommend

Colour: Black

Really easy case to build in for my first time build. Has enough room for everything. Not too big and not too small that all the components looked crammed in there.

Mesh vents are on the slightly larger size so has been letting in a bit more dust than I would have liked. But the airflow is great and keeps everything running cool. I have put 2 x 140mm Silent Wings on the front with a CPU air cooler for good front to back flow.

Great Airflow, Easy to Build In

Colour: Black

Excellent case, not as small as others but that offers much better options for cable management.

Everything runs extremely cool. Highly recommend looking for someone trying to shrink down from a standard ATX case.
