Product Overview The MasterBoxQ300L is your straightforward option in the lineup of the brand new MasterBox Q-series from Cooler Master. A series that might be small in size but excels in functionality and modularity without compromising on the thermal performance.

Although the size wouldn’t tell, the MasterBox Q300L supports a standard ATX PSU which we don’t see often in the market with this size. Based on the different system setup, the I/O panel can be adjusted to six different locations, three options at each side of the case. You can decide which setup fits your system best.

Due to the cube design of the frame and special pattern design on the magnetic dust filter will make the chassis stand out from the rest. The combination of a practical design and the unique customizable outlook makes the MasterBox Q300L the perfect choice for office and home usage. Features • High Flexibility for System Building: The I/O panel can be adjusted to six different locations. On both side of the body you can install the I/O panel at the front, top or bottom.
• Minimized Dimension with ATX PSU Support: Despite the Micro-ATX form factor and the body depth and height of only 370mm x 370mm, the MasterBoxQ300L can accommodate a normal ATX PSU.
• Patterned Dust Filter: Special pattern on the dust filter creates a unique outlook for the chassis.
• Clean Routing Space: Behind the motherboard tray, it offers 28mm wide and spacy room for hidden cable management.
• Excellent Thermal Performance: The open design of the perforated front, top and bottom guarantees excellent thermal performance.
• Edge-to-Edge Acrylic Transparent Side Panel: Show off your build through the full size transparent side panel.
• Vertical and Horizontal Position: The case can be put in vertical and horizontal position.

Reviews
Cooler Master MasterBox Q300L, Black, Mini Tower Computer Chassis, w/ Window, micro-ATX/Mini-ITX, 120mm Fan, USB 3.0 is rated 4.7 out of 5 by 3.
Rated 4 out of 5 by from This case has potential! Pro's: On the sides of the case you can fit fans wherever the holes line up, yes there are holes smaller to indicate where the fans go but you could fit even two 240 rads if you have enough clearence from the motherboard.(would recommend the smallest pump/res you can find if you are trying to do this) The case can be any orientation you choose, be it flat, upside down or vertical as the feet are removable. The case has a nice side panel to cover cable management and storage drives. Con's: The window panel is standard plexi, the PCI-e covers are not reuseable and air flow will be restricting if you do not you High static pressure fans. Final summary: This case is awesome and compact, i get its cheap but a second Gen case with Tempered glass, reusable PCI-e covers and better materials would be a treat.

Rated 5 out of 5 by from Bloody Excellent I wasn't expecting much for the money but actually, this is one of the nicest cases I've ever done a build for someone. Everything is very easy to get at and the cable management system is excellent. My only issue is the magnetic filters weren't quite flat but as it's a covered in a design you can't actually see if it was flat or not. For my own build I am doing later this year I will be looking at Coolermaster cases more after this build.
