Can someone give me some insight into whether or not the following would be possible? 1. Buy an $1150 iMac (Student Discount). 2. Remove internals (Power supply, Motherboard/RAM/CPU/HDD/Superdrive Unit). 3. Replace GPU with ATI X1900XT (Used in the Mac Pro). 4. Reinstall in homemade case/purchased case. 5. Hook up to dual displays. Would there be a driver issue for the new GPU? Is there a specific Mac version of the ATI X1900XT? I've built my own PC's before, and I'm curious if this method would get me my screen-less iMac with dual screen capability and nice GPU? It would also save me about $1000 from purchasing a Mac Pro and equipment I really don't need.
