That is cool, but personally, I would just buy a rack. I purchased 3 new 42U (for the unfamiliar, that's roughly 6'6") 4-post racks locally last week at a cost of $450 CAD each plus another $100 CAD for delivery (dude with a truck, not a big courier). Fully enclosed, fans on the top, 1 movable shelf, castors and a (albeit terrible) PDU. I bet I could find something similar in the realm of $100-250 CAD at a smaller size with similar features. They're not the greatest but they're definitely better than an Ikea coffee table. There are decent cheap racks out there, it's not like you're forced to buy either a APC NetShelter or a coffee table.
