Does this look like a good buy

Hi I found this on ebay.

http://www.ebay.com/itm/Custom-gaming-laptop-Intel-i7-4810MQ-8GB-RAM-NVIDIA-GTX-870M-6GB-1-5TB-HDD-/272135146923?hash=item3f5c84cdab:g:hMoAAOSwUuFWwiG-

I was wondering if it was a good buy. And if it looked like it was upgradeble. Since it sort of looks like a clevo right and a clevo with that high end a video card is probably an MXM one right? ALso you are able to add squaretrade warranties to these laptops right?
