Err Lee, I think you mean in series! Its a relatively simple mod but you have to make sure that at least one of the units you isolate the 0v rail from the metal case and mains ground (normally the case is 0v and mains ground). If your modded unit is PSU2 and the unmodded PSU1 then you wire the isolated 0v rail of PSU2 to the +12v output of PSU1. The +12v output of PSU2 is then +24v relative to the 0v rail of PSU1. This will typically give you 5 - 6A at 24v and 300W PC supplies are dirt cheap on ebay.
