Cooler Master Introduces the MasterCase SL600M Cooler Master, Cooler Master MasterCase, FreeForm Modular, mastercase, MasterCase SL Series, MasterCase SL600M, SL600M 1Back in August of 2015, Cooler Master completely revamped their case line up with the release of the MasterCase 5 and Pro 5. These were the first cases to feature Cooler Master’s FreeForm Modular System.  This system was designed to give you the flexibility to customize and upgrade your case’s look and functionality. It does this by offering an array of accessories to help in the customization of your case. You can also remove, or just move many parts of the case both inside and out. Using a case that features Cooler Master’s FreeForm Modular system gives you the ability to take one of their cases and truly “Make it Yours.”  We’ve reviewed several of the cases in the Master Series, each having this FreeForm Modular system and ranging in size, quality and price. Some of these cases are the MasterBox Q300L and MasterCase H500P, just to name a couple. Now, Cooler Master is adding another case to their ever-expanding Master Series of cases with the introduction of the Cooler Master MasterCase SL600M. The MasterCase SL600M marks the start of the SL series, designed to blur the lines between work and play.


Clad in sand-blasted anodized aluminum and sans any RGB features, the MasterCase SL600M is designed to be the centerpiece of a home office or workplace with the capability of powering a high-end gaming setup. “Fusing together professional aesthetics and gaming functionality took more than just exterior changes, it demanded an altered perspective on system layouts and cooling,” said Matteo Stracciari, General Manager of Case at Cooler Master. “Instead of using brute-force cooling methods, the chassis takes advantage of the natural rise of heat.”

Taking a new approach to the internal layout of a PC, Cooler Master reconfigured the SL600M to truly have a vertical layout and take advantage of the natural convection of heat. Equipped with two 200mm intake fans at the base and with the PSU oriented at the top front of the case, the SL600M provides a more direct path of airflow to the internal components and funnels warm air out through the top mesh of the case. For increased expulsion of air, the top panel of the SL600M can be raised to rest atop the mesh covering or be completely removed.

Vertically mounting a graphics card is also no longer just an aesthetic option. With the SL600M, the PCI mounting window can be rotated 90 degrees to allow for two graphics cards to be mounted vertically, in tandem, and allow for more direct airflow to the GPU. With decreased temperatures, the GPU fans are less likely to be triggered and help to decrease system noise.

The front I/O of the SL600M is outfitted with the connectivity needed to support both creative professional and gamer’s needs. With one USB 3.1 (Gen 2) Type-C port, two USB 3.0 ports, two USB 2.0 ports, a PWM fan speed slider, microphone jack, and a 3.5mm headset jack, the SL600M aims to never leave a user searching for a spare space to connect their accessories. A proximity sensor positioned behind the front panel triggers the temporary illumination of the USB ports for easy plug-and-play access.

Backed by a two- year limited warranty, the MasterCase SL600M is available for pre-sale, today, for a starting MSRP of $199.99 USD. For more information please visit:
