If you've already got experience doing hackintoshes you can't beat building your own Xeon machine and just dealing with a few hours here and there of update headache.
The price of raw commodity hardware is suuuuper cheap compared to off the shelf macs. There are even nice mini-itx cases if you want a powerful, slightly-larger-than-mac-mini machine.
Updates were a headache and the inability to install pre-release software.
But with Xcode and Swift being so slow I'm thinking about going back there and just getting the 4ghz i7...
Another option is a Mac Pro, but I really don't have 3000+ money to spend on a computer...
