I'll update this thread if anything changes, but at the moment I think this is a done deal. I'm going to be swapping systems around so that the systems where I do the most typing have the keyboards with blue switches, and will probably pick up a similar KB for the office.
Other notes :
The Corsair K65 also has a detachable USB cable, and nicely protects it by routing it through a small channel then out the back.
Moving the switch on the back of the K65 to the "8" position (it came set to 1, with choices of 1/2/4/8) makes the caps lock light work, but then the scroll lock light flashes constantly. Need to try the Razer KB on Linux (I plugged it into the Windows box yesterday) to check the caps lock / scroll lock lights there.
I still prefer the looks of the K65 over the Razer and CM Storm, but at the moment I would take even an ugly keyboard with blue switches over a nice looking keyboard with red switches, even though the red switches are a huge improvement over run-of-the-mill keyboards.
