OK, I think that you're "mixing metaphors" here. To switch chips 
would mean to pull the 80Mhz 68040 out of the 840AV's motherboard and 
shove it into the 800's motherboard, trying to essentially overclock 
the machine. The "chip" has no VRAM or VRAM sockets...what it sounds 
like you're trying to do is swap *motherboards*, essentially using 
the 800's case and power supply to drive a Quadra 840AV.

As long as it physically fits (you'll need to cut port holes), I 
don't see a problem with using a Q800's case for an 840AV if there's 
a problem with the 840AV's case. If the 840's case is intact,though, 
I don't see the point ;-).
