No, not the CPU upgrade :) I just want to share with everyone that I "upgraded" my display by exchanging my 22" cinema display for 23" one (translucent of course) + some cash. :) I don't really need it, but I guess this was a rare opportunity to get it so I just had to take a plunge. Besides, 22" display had a mechanical power button which simply does not fit with the Cube ;) I *still* don't feel the need to replace my stock 450 MHz CPU! :)
