Inside the Masterkeys MK750
The standard set of keycaps are single shot keys, which have been painted black. These do tend to wear the fastest, but to be blunt, it has not been an issue with other Cooler Master keyboards with years of hard usage on them. The optional keycaps are two-piece but not double-shot in the traditional sense. One thing is for sure though, that purple will never wear off.
With a few of the keycaps removed, we get a clear view of the Cherry MX blue switches with opaque plastic used for the body. We can also see that not only will light flood the exposed aluminum plate, but all of the torsion bars are internal, and have helper stems on them to make keycaps removal a breeze.
While many companies will add a few thin ribs running from left to right across the frame, Cooler master looked at another way of supporting the aluminum plate. Many plus-shaped studs are found in the lower frame section, which has led to a keyboard which is solid in feel and lacking vibrations that some lesser keyboards have.
While the color of the PCB matters very little, we do tend to like it when they are black. What we find in viewing it is that attention to detail is not lost in the slightest, even inside. There is not a single sign of any flux residue, and this is some of the cleanest solder work we have seen on any keyboard to date.
We already knew that there is a 32-bit ARM Cortex-M3 MCU used to control the MK750, but now we can see the specific model. In this instance, we found the Holtek HT32F1645, and even with the feature set presented in the Masterkeys MK750, this MCU is plenty capable of the task.
For this image, we are letting the Masterkeys MK750 do all the talking, without any added goodies. The board comes to life with a bright flood of RGB lighting, as the default mode is this rainbow of colors which moves to the right, and can be seen on both sides, across the leading edge, and is now illuminating the multimedia keys.
We also wanted to show the Masterkeys MK750 all decked out with all of the optional parts. The purple keycaps are bright, and stand out even in the darkest of rooms. We also like that the RGB LEDs pass through the legends as well as it does with the standard keys.
While we do like the feel and comfort of the magnetically attached wrist rest, it does cover some of the lighting, and with the Lightbars being a selling feature, it is somewhat detrimental to the lighting effects.
