disconnect everything unscrew the mobo pop the mobo in the new case connect everything i'm not trying to be funny. it's like puting together a very simple puzzle... but with expensive electronics one thing you must take notice of are the wires that control your reset/power/hd lights/etc. that gave me trouble the first time i did this. luckily i had xperties' number and he helped me out usually it'll show on your mobo where the wires go, but if not print out a diagram of your board. it's really simple and there's nothing to be afraid of :bigok
