Nice. Did you solder all those, or find a way to open the switches? I've been thinking about tearing down my first keyboard (K70) and maybe upgrading it.
Kane11I11I desoldered the old ones and soldered in the new ones. It was a lengthy process. I had a crappy soldering iron and plastic solder sucker at the time and it took about 10 hours from disassembly to reassembly. Totally worth it though
