Nope it doesn't take long. The case opens with 4 regular screws.
Good that it starts to get interesting, like opening a case box for a drive-train transimission.
Loving this more and more every time I see it. Now this is what having a Model-F type keyboard should be
.
If you need to open it, break out a phillips and get busy, like working on a vehicle as such.
After viewing your vid I noticed how solid sounding it is when comparing it to any standard SSK or 101 Keyboard. Has a deep thock but not sounding like a thorpie, almost like it's own sound especially designed for the Model-Fs.
Another thing here that has to be mentioned, is the USB cable which looks so flimsy and the way it connects to the PCB seems so detrimental. Any Gorilla A-Hole can yank the cable out attached to the keyboard and quite possibly damage the connections, please say you will fix this when our models come to our front doors?
Never underestimate human-apes when keyboards are involved.
