I have a CM Storm QuickFire Rapid (QFR). It used to have MX Blues, and I desoldered them and directly replaced them with Box Jades, except under the space bar where I used a Box Pale Blue, just in case it needed a stronger spring for rebound.
I've been using it as my keyboard at work for a couple of months now. It works wonderfully. I have no problems at all with keys resetting, and I am a fast typist who gets up to 100 wpm when I'm at full speed.
The only thing I'm not completely satisfied about is the weight of the spring--i want it slightly heavier, somewhere between Jade and Navy weight. I think either some 50g or 55g SPRiT replacement springs will be perfect. To determine which of the two I like best, I'm going to experiment with both weights when my Massdrop CTRL keyboard arrives, since it has hot swap switches. Once I've found my perfect weighting, I have two other used QFRs in the wings, ready to receive new switches. That'll be Cherry switch end game for me.
So to make a long story short, yes you can directly replace cherry switches with Kailh box switches in your QuickFire Pro.
