Hey guys, I got my frist mac a few days. I simply got tired of putting up with Windows. The thing is that the HD is gonna die on me relatively soon. So I got a replacement one which is a 160 Gb, 2.5" EIDE, 5400, 8Mb, OEM. I dont know which one I should have gotten and this one seemed as the best buy for the money. Will it work without any trouble ???
