I've found one retailer that appears to still have one of these out of production boards in stock. It would simplify rebuilding the system in that the Windows XP home should not have a problem and force me to reactivate the OS. However, I have some reluctance to go back with the same board and an old one at that.
The only thing I would really like to add in a rebuild would be an eSATA connector. The other system components are a DVD ROM, CD R/W and floppy. I don't remember the last time I used a floppy (other than as a substitute throwing star) so a floppy connector is of no consequence.
Does anyone have recommendations for a board that would allow me to keep the old process and memory.
