This is cool, i don't have enough to build a computer but if i did i would.I read about building laptops and computers, they all say that it's hard work but very rewarding at the end.I would go with Windows because I have a mac at the moment and mac requires more things in a computer and it will cost more. Also, games are limited and the graphics card is shared with the motherboard and it's rubbish.Also, some applications you cannot get on a mac you can get on a windows and i'm not allowed on the home computer anymore :)Good Work On This Tutorial-Lewis
