Hi Raphael, I think you may be able to make the case work, but I would not recommend trying to use the old power supplies on a new mother board. It may not meet the specs. required and you would end up losing it. Most cases are designed for optimum airflow for the MD they are designed= for. Mike ~ It is a good day if I learned something new.

It has lots of front slots and internal HD mounts, and is a really great case. Could I get a Pentium 4 compatible back plate with all the card slots and mount it in the back (or can I use the 486 back plate), and mount a few cards, like a sound card, modem, video, and so on, in a Pentium 4 mobo, can I line it up with the slots so the x/y/z orientation is already lined up, and mark and drill the case backing plate, so I could use the 486 case for a Pentium 4 mobo? Or is it that things just don't fit somehow? I don't have Pentium 4 mobo yet, so I wouldn't have any way to check it out myself yet. Is a 486 power supply totally incompatible (might not be powerful enough anyways) with a P4 mobo? If a 486 power supply would work, could I use two of them in tamdem somehow to double the power?
