Compatible? Alienware 17 - R1/R2/R3/R4/R5

Will any version of these work in another system? May need to order a new MoBo, prefer to get an R3 or higher because they have a hard reset option for the BIOS.
R1/R2/R3/R4/R5

Thanks.

I answered my own question, after comparing the images, they are different enough, ports, ect.

Yes, completely different boards between the models. The R1 was the last socketed board (replaceable CPU and GPU). From the R2 they are all soldered.
