The filco is pretty loud, though. Quieter than a pcb mounted keyboard with blues, but, if you bottom out hard, it's not much quieter.
For somebody who is not used to mechanical keyboards (i.e. the coworkers), it's a hell of a loud keyboard. I much prefer plate mounted keyboards and love my brown filco to death, but if you bottom out and low noise is a high priority, get a pcb mounted board. If you don't bottom out, you can probably get away with a filco.
