$350 budget build

I wanted a PC that can run minecraft, older cods like black ops, mw2, waw, and cod 4. At first I wanted to go with linux, but it doesn't fully support on linux. I already have my my main rig (i5 3570k, radeon 7970) so these are all the games I want to play. I also would like if it was portable. I obviously don't need mini itx.

Wait so, $350 with windows? Or without?

Would this suffice? You would just need to buy a laptop charger or if you have one laying around would be fine, also very close to budget even with purchasing windows. LINK

Do you need an extra keyboard and mouse?
