Cheapest hackintosh?

Hey guys! I was just wondering if anyone knew of the cheapest hackintosh build or configuration with everything working. I just need something that will run OS X Mountain Lion well and might be able to dual boot into Windows 8.

Also, does anyone know of a good 15 inch high-res monitor? Preferably a touchscreen but those are hard to find. Thanks! 15 inch screens are the only ones able to fit into my iMac G3 mod.
