I am looking for a computer that I can expand like I did with PC's for years in stead of buying a whole new one down the line like I would with the iMac. I am not a Pro user with video which is what I would like to use most (FCP and AE etc.) but buying an all in one is just scary to me and not having control of being able to put in new hardware as I need it. For armature video editing but still editing in HD what is your suggestions.
Well, with the Mac Pro, you pay a lot for it but you get expandability in return. You will be able to upgrade the graphics card, RAM, add up to 4 HDD, 2 optical, upgrade to USB 3, and even add any of those new SSD PCI-Express drives, among other things. You
should be able to upgrade the CPU, provided the motherboard is compatible with Gulftown. I don't see why it shouldn't be. In the past the Mac Pro had pretty good luck going from one CPU family to another. But with like any motherboard, CPU compatibility isn't carved in stone.
With the iMac, obviously your upgrade option are limited. RAM is upgradable, and the HDD and optical drive should be upgradable with not too much effort. You can't fit more than one of each drive in the chassis, however. CPU upgrade is pretty unlikely, without a complete mobo replacement. The GPU is on a card (MXM slot, I believe) but those are not available from 3rd party vendors; you would need an Apple branded one and it would be from the grey market.
