Removing both panels from Q300L we can now gain a better understanding of the internal design and features. This case can accommodate Micro ATX and Mini-ITX form factors and while being quite compact, still allows for a decent assortment of hardware to be installed. There is room for both 3.5” and 2.5” drives and reasonable space for maintaining good cable management as we’ll see later on!


In the lower region we have the area for installing the PSU which we’re pleased to report has the rubber mounts for anti-vibration and soft cushioning. Quite a few cases which hold a bigger price-tag than Q300L lack this simple feature so this is well worth mentioning. Cooler Master has included an adapter bracket for installing the PSU – this will need to be removed and attached, before the unit goes in.


As we mentioned earlier, there are four PCI covers inside Q300L, all of which are disposable. Above this there is a 120mm rear exhaust fan which is the only fan found within this chassis, though there are optional spots such as those at the top of the case for installing additional cooling – the top can house 2x 120mm fans.


Towards the front of Q300L there are two sets of SSD mounts sat directly on the motherboard tray. For larger drives the back of the motherboard tray features a 3.5” drive adapter – on the next page we’ll install our test system inside this case and report back on the experience!
