XT Case with Modern Motherboard

[John Boffemmyer IV]

Sridhar, I've done this numerous times with AT's for clients in the 
past. XT's it sounds, are a little more complicated. Jules and the 
rest of the gang are on the right path with having to mount the ATX 
mounting tray in it. If you need help though, I do have a 20k rpm 
dremel kit with cut-off wheels to make short work of the backside of 
the case to make room for the ATX ports (ps/2, serial, parallel, etc).
