It's not for you then FWIW I find the small form factor combined with the CPU and high-powered integrated GPU very appealing. I don't think I could build something with this form factor using off the shelf parts (someone correct me if I'm wrong)... it would end up needing a larger dedicated GPU. I suspect their competition isn't actually people who build their own PCs, but people in the market for Mac Pros — they have a number of benefits over Apple here.
