About the Masterbox K500L…

The Cooler Master Masterbox K500L is a PC case expected to be somewhere before or between the Cooler Master Masterbox MB500, depending on what you want and can pay for. The comparison is made with the Masterbox MB500 because that’s what it is. The main difference is the lack of additional features and different front panel design. There are also some minor differences such as the installation of the front panel I.O- beauty is in the eyes of the beholder.

Packaging and Contents

Nothing really new for a case of such class- a brown box with specs listing. The K500L is protected by two foam blocks and a plastic wrap. The contents are bone-dry bare basic- just screws and cable ties. You get a couple of reading materials and that’s it.

There are two sub-variants in the Masterbox K500L- naturally the second is with the sidepanel. Not sure why it has the extra 5mm height. The case allows you to install radiator size up to 280mm towards the front.
