Cooler Master SK650 and SK630 low profile keyboards
Cooler Master launched two low profile mechanical keyboards from its new SK series, the SK650 and SK630.
“We created the SK series with design and functionality in mind. Especially for those who are workers by day and gamers at night.”
says Bryant Nguyen, Peripheral General Manager.
The SK650 and SK630 are slim profile mechanical keyboards with the perfect balance of “work and play.” The SK series features Cherry MX low profile switches that provide a reduced travel distance and actuation point with the same signature durability and precision as a standard red switch. The boards are equipped with Type-C USB for convenience. Per-key backlighting, surrounding light bars, and macros can be fully customized through Cooler Masters easy to use Portal Software Application. On-the-fly-controls allow real-time adjustments to lighting and macros without the need of software, including Windows Lock On/Off to prevent accidental actuation during game play. Users can choose from two sizes depending on preference. The SK650 is a full layout keyboard while the SK630 is its little brother, a ten keyless layout for users with limited desk space.
Cooler Master will also release a Bluetooth and wireless version of aforementioned keyboards later this year as well as the SK621, a 65-key compact keyboard, perfect for on the go, available in late March. The wireless versions, SK651, SK631, and SK621, will be available in gunmetal black and later also in white. Cooler Master will offer models that are Apple and or Android compatible.

The low profile switch is only for some few spec right now but i guess it will be extended to all switch color.
i don't remember exactly but i think it is the silver speed one with the fastest actuation if i remember right (search yourself as i am in GSM 4G Data under snow in the moutain right now lol).
Have fun there

I am now with Omron Romer-G. And quite unhappy that one can't place anything under key to make total travel shorter. But from mechanical perspective it would be possible by having keycaps which have inner profile done in way that it hits top of the switch casing. But no such keycaps are around. Other than that it is good keyboard.
Here is what you referred to: MX LOW PROFILE RGB SPEED
Clicks at 1.0mm, total travel 3.2mm. But at least MX switches can be easily modified with rubber rings to reduce that total travel.
