MULTIPLE TRIM COLORS
Make a statement by choosing from three different colors of side trims, including Red, Blue and Silver.

BRUSHED FRONT PANEL
The font panel features brushed texture design, giving an elegant appearance in any environment.

FAN SUPPORT
One 120mm fan is pre-installed in the front. It can be replaced with an 80mm or 90mm fan. The rear supports a single 80mm or 90mm fan.

SIDE PANEL VENTILATION
The perforated side panel increases air intake to directly cool the CPU effectively.

MAIN COMPONENTS CLEARANCE
The MasterBox E300L supports high-end components including CPU coolers up to 363mm in height, graphics cards up to 363mm in length, and power supplies up to 180mm in length.
Pros: - The front mesh allows for way better air flow vs its counter part MasterCase H500P. - Edge to edge transparent side looks real good. It is actually glass/acrylic, not some cheap plastic. - Fairly easy to build into. Plenty of places to tuck cables and or clip them to a side. All the edges within the case are dulled and cruved-ish. - Has a lot of support for different radiators and configurations. I could have my choice of putting my 240mm rad at the top or the front. Front can take up to a 360mm rad. - Nice power button and front panel design. - Removable fan filters for top and bottom vents. Top is magnetic. Bottom is clip based. - Bottom mounted PSU with a shroud.
Cons: - A bit on the heavy side. Construction is mostly steel/plastic as with most cases. Would've been nice to see some aluminum for a lighter weight, but I guess for the price, it is okay. - While the mesh design does allow for way better airflow and thermals, it will produce more visible dust collection on the outside mesh. - One bundled fan? Cooler Master cheaping out in this department. :\ - Limited 3.5" HDD space. Only 2 slots.
Overall Review: Overall a decent case. Currently using it as a Ryzen 7 build. MSI X370 Gaming Pro. Corsair RM750 and a Corsair CPU water loop. Everything fits very well.
