IIe case, PC motherboard

[nospam@getreal.com (Darkstar)]

I've encountered quite a bit of information about migrating a IIgs motherboard 
to a PC tower case.  A worthy project, especially for the advantages of the 
more robust power supply.

But has anyone experimented with a move in the opposite direction?  I'm trying 
to mount a PC motherboard in an enhanced IIe case, and would appreciate some 
advice.

First, where can I find a useful cooling solution?  I don't want heat building 
up, of course, but when I get the PC power supply mounted in the box, the fan 
will only move the air around inside the case.  I seem to remember something 
about an external fan from Kensington for IIe's, but I don't know where I might 
find one.

Second, has there ever been a circuit designed, even prototyped, to make an 
adapter for the AY-3600 keyboard decoder to work with a PC keyboard BIOS?  It's 
a stretch, I know, but I'd like to be able to use the IIe's keyboard with my PC 
motherboard.  Any EE geniuses want to take this up?  :)

I should be using an external SCSI tower, so the hard drives/CD-ROMs aren't a 
problem.  I'll even use an old floptical drive, if I have to, to avoid cutting 
up the case.

I'm sure there are other Issues(sic) to be dealt with that I haven't yet 
considered.  Any advice (other than "don't profane the IIe like that!") would 
really be appreciated.

Thanks in advance,
