May Purchase Alienware 13 R2 with problem

[niceties55]

I am looking (on eBay, good seller rating) at one of the top of the non OLED Alienware 13 R2 with the 965m 4GB graphics card and right now it is super cheap. The problem is (to quote the seller) the person before him accidentally broke off the part where the keyboard goes in to the motherboard.
Other than the keyboard not working, it works perfectly?

I was wondering how hard of a fix this would be? Would I have to buy a new motherboard? I see Alienware 13 motherboards for this online for about $300-400 which would still make it a very good deal. My question is, can I buy a cheaper (all of these have processors built into them) motherboard with an i5 in it and replace it with the i7 that comes with the laptop?

I have repaired and built computers before so I am not a novice to this, but I really haven't done a laptop before. I was just wondering how possible this repair is.

Thanks!

I wound't buy a laptop like that, not knowing if you can fix it and how severe the damage is.

Make him take some close up pictures of the damaged port. It's gonna be a risk.
