Cooler Master has launched a new case in the MasterCase H500M. The latest addition sits on top of their H-series lineup and seemingly based off of the H500P with some notable design changes including more glass panels and addressable RGB lighting on the front 200mm fans. The case includes both a mesh and glass front panel so users are able to choose between maximum airflow and aesthetics with Cooler Master stating the front panel options compliment the industrial design of the H500M in their own method.


External styling is quite simple with mesh features on the front and top of the case for ventilation, with glass in the middle. Other external design features on the black chassis include an angled front IO panel which has four USB 3.0 ports and one USB 3.1 Type-C port. The included ARGB controller is also located on the IO panel along with the power/reset buttons and audio in & out jacks. On the back of the case, Cooler Master has added two vertical PCIe slots to set up the video card vertically and show it off through the glass panel. The glass panels are held on by relatively flat screws seemingly requiring a tool for access. 

Internally, the chassis is able to support up to a Mini-ITX size board all the way up to E-ATX size. For storage, the H500M has six 2.5-inch SSD bays and two 2.5/3.5-inch drive bays for a total of eight bays – plenty for most users.

As far as cooling support there is room for a 190mm (tall) CPU heatsink and numerous locations for water cooling/radiators. Both the top and front panels support up to 360mm radiators with an additional location for 120/140mm on the back. There is even a dedicated water pump bracket on top of the PSU shroud. The case comes with the two 200mm ARGB fans controlled via the included controller as well as a single 140mm fan on the back.

There are plenty of internal covers and shrouds, nine in total, to route and hide wires which should make for a clean internal appearance. The PSU shroud has a cutout cover giving users the option to display the PSU or leave it hidden. Towards the front of the shroud, there is even a removable plate for when using thicker radiators.

GPU support is up to a long 412mm and includes a graphics card support arm that mounts to the chassis. This rarely included and occasionally needed item is designed to help reinforce larger/longer graphics card and prevent sagging.

The MasterCase H500M is available for pre-sale as of now in North America with a starting MSRP of $199.99.

    I was so looking into maybe getting this case and then you deflated it by posting the spec's for it and it only supporting 2 3.5 drives. I know it's not your fault never said it was. I have found that most of the 2018 cases have reduced 3.5 drive support to either 1 or 2 drives to make room for more open space inside the case. I have 4 4TB drives as storage and installing them to sit on the bottom of the case is not an option. I guess I will have to look into the Be Quiet 700 case I think it has space for up to 7 3.5 drives which is to bad because I really liked the looks of this case and would have made a nice case to build in.

    It would seem that in 2018 HDDs are for NAS, and SSDs are for computers. Personally I am annoyed that with all that space, no room for even a slim optical drive anywhere. I realize not everyone needs one... but it would be nice to have an optional spot for one even if not in a traditional top/center/front location.

    lack of ability to use multiple drives is automatic no sale (for me at least for 3.5 size) as rocky stated, also for my $ screw the glass and RGB cases as far as the eye can see.

    I want proper dust filtration (such as Fractal Define C which has amazing dust filters IMO)
    removable PSU "shroud" so makes easier to wire everything up instead of fighting with it
    enough front to back room and height so one does not have to bend sata wires out of shape

    as well so many cases really cramp up the top section for trying to fight gettings fans or AIO/liquid into them because of not enough height between top and motherboard >:(

    I do like the bunch of front panel USB however, really really would like to see them do something like this for a "non rgb glass monstrosity" I personally have always HATED CM cases because the majority of them tended to use cruddy mesh with sponge type filters that are difficult to keep clean which makes case look like crud or no filter at all, this one does not seem like it would be any better.

    not to mention that price (for me) all that RGB and glass BS might make a "show case" I rather them put a stealth type case where solid panels of decent no flex design etc, I think this case would have "potential" but I honestly am not overly impressed with CM these past couple of years, they rebrand "new" models from the same old base design and "upsell" using "master" in their name and up the price $20 or more versus their "old" line.

    I understand they are in business to make money and all that, and they have had some pretty decent things over the years, but seriously CM try harder to be "honest" and not look at making a quick buck, go against the trends and make awesome stuff instead ^.^ (for example, claiming HSF can handle 180w when they can barely handle 120w safely LOL)
