^ Thanks Mate.
The Intel motherboards are always a solid choice. Your case seems to come with a power supply. I usually say to get a name brand solid power supply as it's the heart and sole of your computer. Anything from Corsair, Antec, Seasonic and you cannot go wrong.
For light computer use, 4GB of RAM should be more than enough.
Might also suggest the Antec 300 case. It's currently $45 at NewEgg. It's not as flashy, and doesn't have a power supply...but it's build solid, it's quiet and it has a dust screen in the front which really helps to keep your computer clean. I've got 3 of these cases at work and I love them.
