Probably not too much. First off, do both computers use the same type of hard drive? (IDE or SATA?) Also, do both computers use the same RAM? it looks like the evo uses DDR, and there are many dv6000 models, so I am not sure what that uses. Motherboards will most likely not work at all, especially if it will not fit. Most likely you barely can switch anything over. You will have to give exact model # of the dv6000.
