Under-desk mini mounter
Cinammon Peripherals has shipped the CinnaMount mini Industrial Edition, a new raw aluminum mount that allows Mac mini owners to secure their Mac mini and Mac mini-sized external hard drives under their desks. The mount is much thinner than similar plastic mounts, which are usually 1/4" thick. The instructions manual and drilling guide are available as free downloads. The new model is sold as a kit which includes a small aluminum mount for the Mac mini power supply and is priced at $35 Canadian, or around $33 USD. [corrected]

Material?
Forgive me, but which is it?
"...a new plastic mount..."
"The mount is made of raw, non-anodized aluminum..."
I'm guessing it's aluminum from the pic.
