I'm expecting my Wyse KB to come in today with MX blacks. I wanted to strip that and put them in my Razer BWU. I opened up my black widow but having trouble removing the cap on top of the blue switch. Any tips on how I can remove the cap so I can replace the blue with the blacks? I tried to pry it a little with screw drivers but it doesn't seem to budge and I don't want to break anything. Thanks in advance.
