When I first got my Octagon from Synjn back around June or so, I had never experienced anything plate-mounted (before this, I did switch swaps and SIP socketing, + a small layout rewiring with two Rapoo KX keyboards), and so I did not realize that Cherry MX switches had little retaining clips that locked them into the plate. Very little solder was used and there were SIP sockets that were either flush or recessed into the PCB.
For those wondering, I wanted to change the layout and I wanted to customize the switches (and get rid of the MX Greens) to my liking.

I literally desoldered the switches, held the PCB upside down and used a torx driver to forcibly shove the switches out of the plate by pressing against the stem well of each switch. It was violent. Very violent. I actually had a little box under the PCB to catch the switches when they were flung downwards at high speeds.
It pretty much goes without saying that I had some ruined pads and LED traces. Miraculously, I somehow managed to fix every single issue despite a myriad of problems. I was determined not to let my $450+ purchase bite the dust.
I'm not sure if the plate was bent or what, but my technique was so terrible with plate-mounted boards due to my aforementioned inexperience, that I had to wedge the plate up with strips of solid neoprene to stop it from being pushed down (even with switches mounted). I think the switches did clip in, but the plate was just loose. It might've gotten slightly bent from all the trauma, lol.
Now I have a tool I use to clip onto switches and pull them out of the plate and I also use ChipQuik for desoldering those kinds of SIP sockets, as it makes them like 80% easier to desolder. Even using a vacuum-powered desoldering iron doesn't make THAT easy without ChipQuik.
