Gigabit Cube!
It appears that Jeff has the only Gigabit Cube in the world. Now if we could just get someone to make the rest of us an upgrade. Too bad Apple won't sell the leftover Gigabit Ethernet parts from before they EOL'ed the Cube; Gigabit Ethernet was going to be a build-to-order option. What a killer little server this box would be, especially after you popped in a processor upgrade.
