ok, just got a nice iomega external super dvd writer, well, its usb 2.0 compatible, my desktop has usb 1.0 and it takes me an hr to burn a dvd

so my question is, how easy is it to put a usb 2.0 card in my HP Pavilion 750n

i can get the crad for under 10 bux, so id like to do it really soon folks
thanks in advance,
bean
