Need new computer advice...

After tons of searching, I think I've finally found the computer I want, but it seems almost too good to be true! I'm looking for something I can play most of the new games out now at a decent rate on at least a medium graphics setting. Mass Effect is the one I'm thinking of right now, as my current computer is just too old to handle it at all.

It has everything I can think of that I want, including the 700W psu in case I would like to upgrade the graphics card in the future to do SLI or w/e. It's just sooo much cheaper than anything I have seen with these specs so far, and there is only one review that I don't know how seriously to take.

So, does any one see any reason why this wouldn't be a good starter gaming PC? anywhere else I should look before I take the plunge?

Thanks!
