Apart from the possible wood panel perforation, I loud like to suggest two more accessories. If people like the idea/make it better as its a quick 3d sketch,i hope Aiboh can make a poll to see how many people will want this for the matx and atx case.
Here it goes.(please forgive potato render)
Make a simple 17/20/23mm max extrusion to a aditional left side panel(obviously add the vents and all).Just a simple extrusion and than people can add up to 165mm tall coolers and free all the fan slots from AIO if needed.

You can see that the extrusion is centered so you can modify a existing panel without to have problems with the existing attachment.I loud definitely buy such a accessory.
The other thing is kind of stupid and i was having doubts about posting it so please dont laugh too much
Right side panel that can hold a full atx psu and some space for a nice rats nest of cables.You can use the existing holes on the motherboard tray,or dril one more at home and take out as much cable as you need and leave the rest inside the panel compartment.

(But i hope silverstone makes a revision to that crap 800w sfx-l psu so that we can do things like we were supose to.)
