Here's a screwier question, but I have been asked it:

W2K dual 800 processor with 9iAS and custom OLAP db, or put the 9iAS on a very old HP (but not too old for 64-bit)?

My initial gut-reaction was "send the HP to Larry for use as an anchor on his boat" and get some cheapo box to run 9iAS but... what do you all think? Unfortunately, Linux has been ruled out for the time being. Old HP and dual are licensed already and cost is paramount... db will be fed from larger, newer HP.
