You can even attach the I / O panel to six different positions so that it's optimally placed in any setup. And the bottom, which consists of a magnetic dust filter, can be exchanged with the other two dust filters.
The design of the Q300L is also full of thought and planning: the side panel made of acrylic glass becomes a lid and the large-area magnetic dust filters are equipped with a stylish mesh pattern, so that they look good on the outside as well. And as always with Cooler Master, these cases have excellent workmanship and reasonable details despite the low price.

The MasterBox Q300L from Cooler Master in detail
The MasterBox Q300L is designed to mount Micro ATX or Mini ITX motherboards. Despite its compact dimensions, this case offers plenty of space in the interior and thus also the possibility of accommodating up to two water cooling radiators. In addition to the classic slot on the back for a 120 heat exchanger can be installed in the front of a 240-mm-copy. However, if cooling with water is not required, the Cooler Master MasterBox Q300L also offers more than sufficient cooling potential. Two 140 mm or 120 mm fans can be installed in the front, with a 120 mm fan at the top and bottom. The back is a 120er preinstalled.
The interior of the MasterBox Q300L is classically equipped and convinces with fine detail solutions. There is enough space for drives, such as a 3.5-inch bay, in which of course a 2.5-inch disk can be accommodated. There is also space for two 2.5-inch drives. The drives can be partially installed and removed without tools. The power supply sucks cool air through the case back, which is also a magnetic dust filter. An opening in the mainboard tray makes it possible to change the cooler or the CPU when the mainboard is mounted - not a given in this price segment. In the front and on the lid, the case also has magnetic dust filters with a stylish mesh grid.
Lots of space for hardware
The workmanship is very high quality and the layout, despite the small size of the Q300L leaves room for a potent system with lots of hardware. The maximum length for graphics cards is a whopping 360 mm, the CPU cooler may be 157 mm high and also for the power supply, the housing with 160 mm enough space for powerful copies in the standard ATX format. The I / O panel has all the necessary connections with 2x USB 3.0 and a microphone or headphone jack.
