their specs look the same, might have missed something. I have noted that the pictures of them look diferent though, one has two fans while another has ventalations holes where the second has a alrge fan. Also, I'm sure they have attempted to make the more expensive one more efficient or added some crap here and there. I'll tell you one thing though, I bought the 80$ one and was pleased with it.
