This one seems like a particularly bad deal. $250 price difference seems like a lot.
A note about the previous ones I did: I assumed desktop hardware since that's what we can build with. Some of them (Gigabyte) are definitely using laptop hardware and I expect others (Alienware) will as well. These are going to be even worse off than my examples.
