From experience I'd say the biggest performance increase would be to get
away from the IDE HD.  It is also the first or second most expensive
portion of your plan.

RAM will help but not that much when it comes to disk accesses.  It should
provide a certain amount of cache for the disk subsystem but teh bottle
neck will still be the the IDE interface. (Though I've seen some IDE
controllers with onboard cache.)

Depending on how fast the money trickles in you'd get some help cheapest
with the RAM, then the SCSI, then the MB and processors.
