I thought it will be easier... But not ass clean. F it, I will make standard top mount case. Sorry for stupid questions, my first build..
Actually, top mounting is easier to design than tray mounting.
And no question is stupid.
What thickness is standard in aluminum cases ? Is 1,5 mm as plate is enough ?
1,5 mm plate is enough if not mandatory for the MX switches to snap in.
As for the case, that's personal preference. What layout do you have in mind?
