In my published Kossel variant, the bed plate is attached to 3 metal pillars that are attached to the lower frame. There are holes in the cork for the pillars. So the cork doesn't support the bed.
The cork provides adequate thermal insulation between the bed heater and the electronics. I have an electronics cooling fan, set to turn on if the MCU temperature exceeds 50C or the stepper drivers produce an over-temperature warning. It never turns on.
Some people prefer to put the electronics and stepper motors at the top of the printer, leaving just the PSU and bed heater SSR under the bed.

Also, having the LCD on the bottom part makes it easier to access when the Delta is standing on your desktop and you're sitting in front of it. I do not like long ribbon LCD cables hanging around and having the LCD on the top of the machine is inconvenient for me.

Last, I think that with DC high-amp, low voltage applications such as having a 12v heated bed (or 24v), having long wires is a bad idea. Keep it all as short as possible.
