Oh it wouldn't be purely because of this issue. My MATX board as it is, prevents me from using anything other than a single slot graphics card, which these days severely limits the choices available because most cards are rather wide and need space around them for cooling. I really need a full sized ATX board to give me more choice. The fact that I would also get a working onboard NIC which would work with Ubuntu out of the box, would just be a nice bonus
