Seeing Cooler Master celebrate their 30th anniversary this year can’t help but make me feel a little old. It feels like just yesterday we were at CES with them for their 20th anniversary. For their 30th they announced and now have brought out a few different products themed in unique Cooler Master purple and turquoise, this includes their MK721 which came out two years ago but even though I love compact keyboards I didn’t end up covering them. Today I’m going to check it out, it gives us a chance to see what the MK721 is all about and check out what they have done to make it the 30th Anniversary Edition.
