My work has a similar model. They're quite nice, and I've gradually been working on how much I'm standing - up to about 2 hours now.

As far as power goes, my desk has a hidden power strip on the underside. It powers the lift feature for both legs (so there's only 1 wall plug), but you can also plug in your monitors so you don't need to have 10' cords on all your equipment. They also sell a power strip that can mount to the top of the desk, so again you don't need very long cords for all your peripherals (phones, chargers, etc).

For network cables you'll still need a cord long enough to travel to the standing height.
