Materials: Rast, a few metal brackets, Benno, Vika Amon
Description: I've been using the Rast bedside table as a perfect 6 space rack for ages. I found the hack here. But this time, I wanted to stack them to save floor space. I stacked them up and secured them using metal brackets I purchased at the local hardware store. 3/4" screws worked perfectly. I stacked them 3 high so I had 18 rack spaces plus 3 2U shelves. Much cheaper than buying rackmount shelves.
For the keyboard shelves, I modified the Benno TV shelf by taking out the middle support and removing the casters. I then stacked them on some standard Lack tables for a little more height.
