not sure if you have solved the problems but just would like you to know that i had my linksys wifi next to the gpu on the fan side and it must have been a few months later and i had to send that card back. i think it must have been overheating cuz the damn thing kept restarting. i tried a different card, same results so i decided to put the wifi card on the otherside of the gpu. so far no major problems.
also for the static noise, you were unlucky!! i first thought that it was the mobo or the on-board audio. didnt like the case anyway, sold it and bought a stacker. i've been enjoying a static free front audio ever since.
