Any Problems With This Computer?

Im looking for a new comp, and i now realize that dell, hp, gateway(ext) are ripoffs. So, Im looking for a 800$(ish) PC Including shipping and someone to build it(im only 13). Off Newegg, I found these:http://www.newegg.com/Product/Product.as…http://www.newegg.com/Product/Product.as…http://www.newegg.com/Product/Product.as…http://www.newegg.com/Product/Product.as…http://www.newegg.com/Product/Product.as…http://www.newegg.com/Product/Product.as…http://www.newegg.com/Product/Product.as…http://www.newegg.com/Product/Product.as…http://www.newegg.com/Product/Product.as…
soo, the problems im wondering about are:
Will the 550watt PSU coming with the case be enough?
Does the PSU come with enough cables(I think that newegg does sell the PSU by itself)
Does the Mobo have anough cables(SATA, ect)
Will the case be big enough for the mobo and graphics card?
That setup is 600+shipping and getting someone to build. Here are the quick specs:
