I just got me a beloved white 24" iMac, which the forum will soon -allow me- suffer me to publicize my new found romance with it, and I was wondering since it's obviously second hand, if I can buy a new applecare for it off ebay or something. Thanks boys and gals. And go apple. p.s. would changing the hd void the warranty/apple care? Could I have it done it for me instead by apple care tec staff?
