1. Cooler Master MasterBox TD500

This case is a 2020 Reddot award winner. It’s hard not to notice this case because of its elegant white design. It comes with ARGB which is an upgraded version of the RGB. Let’s explain that.

RGB is short for Red-Green-Blue LEDs, which basically means they’re lights that can change colors. They’re usually used with 12V LED strip lighting.

Now, ARGB is short for Addressable RGB. That means that multiple colors can be addressed or managed to the individual LEDs. Moreover, ARGBs usually run on 5V, so with that information, you could say that they are more efficient and they generate less heat compared to regular RGBs.

Review

For a mid-tower case that weighs roughly about 17.82 pounds or 8.08 kilograms, it is quite on the heavy side. That’s because it is designed to have room for upgrades, specifically, upgrades like additional fans and hard drives or SSDs.

Its spacious interior fits all standard ATX and Micro-ATX motherboards configuration. It can support up to a 410mm GPU or graphics card, a 165mm CPU cooler, and up to a 180mm PSU in length.

The bigger the case, the more likely it is for you to add a liquid cooling system and additional fans inside. Cable management is not a problem either.

It has a roomy interior and fine mesh in front and on the top panels that support up to seven 120mm fans and a 360mm radiator. You also got yourself a fully optimized dust filtration system and airflow design that supports the front, top, and rear cooling of your build.

With three ARGB fans, the lighting already looks decent. But of course, you can always add more. The crystalline tempered glass side panel provides a strong yet aesthetically pleasing design, showcasing the ARGB system lighting and other components inside.

2. Cooler Master MasterBox Q300L

This is one of Cooler Master’s MasterBox Mini-ATX cases. It may be small, but airflow is still of utmost priority. Liquid cooling installation might be tricky for its size but it’s not impossible.

It has a sleek, black overall design. It gives off a minimalistic vibe compared to other MasterBox cases. It’s perfect for home or even office use.

Review

It only weighs about 1.1 pounds or roughly 0.5 kilograms. That is impressively light and efficient for a PC case. Its I/O or input/output panel is adjustable and can be placed in 6 different locations on the case. You could even position the case vertically or horizontally. It has an acrylic transparent side panel which also showcases your build inside from edge-to-edge.

Considering its size, surprisingly, there’s plenty of room for cable management, specifically about 28mm of open space behind the motherboard tray. It could also accommodate a normal ATX PSU and GPU that fit just about 360mm in length. It might get a little crowded inside but it doesn’t affect performance overall.

Most importantly, the airflow quality stays top-of-the-line. The magnetic dust filters with open
perforated front, top, and bottom helps to keep the dust out and provide excellent thermal performance and airflow throughout.

Whichever style you prefer, you’re still guaranteed an optimized airflow system with the addition of the 200mm ARGB fans and the filtered ventilation on the top panel.

The pre-installed fan lighting system can be easily managed by either the motherboard or the controller that came with it, an absolute game-changer in terms of aesthetics. The tempered glass side panel allows you to showcase your interior build.

Weighing about 15.82 pounds or 7.18 kilograms, this is a light Mid-Tower case. The DarkMirror panel adds a sharper contrast of the ARGB fans from the hardware lighting which enhances the overall look of the whole build.

Air cooling from the filtered ventilation on the top panel, unique mesh intake design, and the 3 pre-installed ARGB fans are all that you really need. But with the roomy interior of this case, most PC enthusiasts opt to upgrade it to liquid cooling.

Control the light vibes you want to give off with the ARGB controller that comes with it. Top it all off with the tempered glass side panel and you got yourself a clear view of your interior build.
