Today: i decided to upgrade my Mac Mini from 1GB to 4GB, 10,00rpm hard drive and take the cpu up to 2.33ghz cpu. All was fine... untill the cpu... i snapped a plastic plug and took me 30mins to clear the cheap thermal paste they use. I had to raid the north bridge heatsink for another plug and replace that with a screw. Knowing that mini's dont use 4gb ram...i awaited to see if the machine would boot.... it did.... 4gb of ram, 2.3 ghz cpu, new hard drive...magic... cpu temperature lower then stock one... mission complete, but for a moment it nearly all went pair shaped. If apple looked inside...well... no warranty for me... afterall shes only 6months old!
