Hi! I ran the system of cooling of the processor G5 Dual 2.7 fluid ran from the power supply flooded fee and now the computer does not work. As in Belarus with the details of the catastrophe I decided to buy in Poland the Power Mac G5 Dual 2.3. Tell me can I replace the PSU 600W at 450 and can I rearrange the cooling system with a processor 2,3 on the processor of 2.7? Thanks for the help
