So i'm not really sure if my PC is able to be a Macintosh, and i'm really hoping it can be.

CPU: Intel Core Quad 2 Q8200 @ 2.33 Ghz
Graphics Card: Integrated
Motherboard: MSI MS-7528 (Chipset: Intel P35/G33/G31)

Thats all the information i can get hold of.
If i can get hold of a cheap graphics card thats compatible with my motherboard and OSX, Will this work with snow leopard?
