It is pretty easy to lift, I am not a strong guy (bench press < 100lb) and I don't have any trouble putting it up or down. The lifting action is assisted by gas springs which you can kind of see in the video but I didn't really mention them.

There is plenty of room for running cables off the back of the desk, I currently have a half dozen cords for charging phone, laptop, etc... and I haven't had any problems.
