Echoing Geoff's article, I'm a big fan of the 51nb mobos from the X62 on. The X62 was very very good, and the T70 and X210 are even better. Can't wait for the X63. One reason I'm taking time off from making X62 backlight kits is to make some new mods for the latest machines-- a 13" 3k screen and internal battery. I've gotten both running, but it takes time to work kinks out of production. It's also why I've been working on my microscope. :-)
