Well, it's not much to see... yet, but it is ALUMINUM. I've been evaluating actuators to drive the CPU Arm - Right now I'm taking a good look at Firgelli Technologies L16 Series Actuators.
The L16's have larger motor for faster speeds and heavier loads. Standard options include: three stroke lengths, three force/speed combinations(gear ratios), Choice of linear position feedback or end of stroke limit switches.
Here's a fine example on YouTube, from LePaul's Build:
