After getting in a lovely clean AEKII case, I transplanted the plate and board from my daily driver AEKII into it. However, then I noticed some looseness around the edges (particularly the left edge and right edge, most notably the top left and top right corner), and some significant case flex when the plastic between the Function keys and the alphanumeric keys is pressed.
The case flex may be simply due to age, but I also suspect that this is an area where the AEKII's relatively simple closure (one screw, minimal clips) is allowing looseness to creep in.
Has anyone experienced similar flex/looseness to this? If so, how did you solve it? I'm pondering using double-sided adhesive tape along the left and right edges, and maybe padded tape inside the case to reduce flex. I've already had good results adjusting for a problematic spacebar on this board (it tended to stick at left side) by inserting a few small pieces of foam tape between the plate and the board under the spacebar, so I'm suspecting that simple reinforcements like this may go a long way towards a more solid-feeling case as well.
