I just saw this item featured in the Feb. issue of Macworld and it might help your problem.
If you have this issue of the mag, it’s on p. 24.
Or you can find it on the company’s website. It’s called the Mi360 and the company can be found at www.macessity.com
It’s along the lines of Jerv’s suggestion. It’s a rotating small shelf mount which can be placed underneath your desk or even on a wall vertically. I’m trying to picture that but not succeeding. But I’m rather a techno tard so that’s not surprising.
The 360 in the name means that you can spin the bracket around for easier access to all of the ports.
Hopefully that might help.
Since there is a Mac Mini in my future at some point soon, I made a mental note of it.
They didn’t show any cables in the one pic in the mag so I must confess that I don’t completely understand how it works regarding cable clutter but I haven’t really checked it out in detail nor even searched for other reviews on it since it’s new.
If you do decide to get it and find it effective, please drop a note back to let us know. I’ll be very interested in your evaluation of it.
