This is a really neat trick I just read about. LackRack is the ultimate, low-cost, high shininess solution for your modular datacenter-in-the-living-room. Its low-cost and perfect fit are great for mounting up to 8 U of 19″ hardware, such as switches (see below), or perhaps other 19″ gear. Featuring the LACK (side table) from Ikea, the LackRack is an easy-to-implement, exact-fit datacenter building block. Installing hardware in your LackRack is easy! Screw all the screws that fit in the rack mount in the left and right leg. The table legs have just right dimensions for almost 9U of rack space for 19″ hardware.
Earlier some hifi people have built hi-fi stand made out of IKEA Lack side tables, but now the world is ready for 19″ networking equipment racks. Check LackRack home page for more information on how to build your own very cheap 19″ rack system. The page also tells that also Ikea LACK coffee table and Ikea ODDA night table have right dimensions and can be easily converted to cheap 19″ racks.
