Let's say you have some rack-mountable servers in your house. For example, you might have a web server for your corporate website, a file server for your terabyte of (un)pirated media, and sundry networking equipment. Let's say all of this gear totals 8U, or about 14" of vertical height.
If you're like my housemates and me, then the obvious thing to do would be to purchase a hulking, steel 42U (over 6' tall) server rack and put it in the the entryway of your house.
After a few years of cohabiting with the 42U monstrosity, we decided that it should be replaced with a smaller, 12U server rack. Ben decided to price this out and found this one ($565) and this one ($341). We looked at these racks, then at their price tags, then back at the racks, and then realized that we were about to drop hundreds of dollars on a glorified end-table.
So, why not just use actual end tables?
Hence, this Instructable. In a nutshell: epoxy together two of IKEA's CORRAS bedside tables. Two are needed because each is only about 15" deep, and most rack-mount servers are 20"-30" deep. The project is pretty simple because these end tables just happen to have exactly the right inside width to fit servers. They even come with handy shelves to set the servers on.
A few photos of the finished product are below (apologies for the crappy mobile phone photos, throughout; it's all we had on hand at the time):
