Of course it won't run OS X well, it won't have the same exact specs, it will have severely worse construction with wires hanging here and there and huge fans, it won't be as silent, it will be bigger, components wont be selected, adjusted and tested to work together, and it might end up costing the same amount of money or near-ish after I add all the options (like the SSDs and thunderbold). And I'll have to support it myself, replacing parts if they fail, instead of just taking it to the Applestore for a fix. But that won't stop me saying it's overpriced.
I can build a PC to the same specs!
