I still cannot decide what to do, either build a new PC or buy an iMac. I love the look and feel of the iMac, but that thing that makes me uneasy is that if anything goes wrong with my PC I can diagnosis it myself and swap out a part; be it graphic card, HDD, RAM, or even the motherboard of PSU. With an iMac, pretty much I can only do the RAM...the HDD [sort of]. So here's my question, how long does Apple support their computers? I'm worried that it will only be supported a very small time frame. I know that iMacs are different than iPhones, iPads...which have limited time frame suport [2-3 years], so spending $2000 on a computer concerns me.
