hmm the only difference with desktops is laptops heat faster.. It worked pefectly on my macbook dude it's just that I have a partition issue so I can't install Windows anymore on it.
I have an old 13yo desktop pc, (core2duo e8400 2.8Ghz, 3go ram, nvidia gts 250) But I gotta fix it, I think there is something wrong with power supply, but changed it already for a 600w)
