$600 max Intel PC build

Ok here are the rules it must be ITX I don't need a case and it must fit into an old Xbox case, I'm going to be putting in an adapter to be able to put the graphics card in horizontal so there wont be any room for a power supply, I'm going to be putting in a mini ITX 300w PSU at the top and running three fans, two small ones pushing out and one bigger one pushing in like this https://www.dropbox.com/s/r1i8zj6d90etuus/xbox%20PC%20layout.jpg . I have to fit a 2.5 inch 500GB drive in and a dvd drive I'm thinking slim drive it has to be 8GBs of RAM.

I'm either going to be clearing the gem at the top of the xbox and cutting the hole out under it to put in white LED's or I will be signing it backwards so it appears the right way when looking at it from the other side lol somehow and painting it white over that, ORRRRrrrrrr getting a new gem made up and getting Microsoft Box engraved in it still not to sure on that either way its gonna be an awesome custom project and i need your help on parts.

will be painting the xbox case white as well i forgot to write that in

How much wattage does the psu supply in 12v? Thats quite a undertaking you have in mind, but i think fitting 600 $ worth of hardware might be quite hard with the space and wattage restrictions.
