IKEA Lack tables are, either by chance or design, the same width as AV and rack-mount computer gear. In this mod IKEAHacker reader Eric Shook needed a cheap and simple AV rack with clean lines. A little measuring, sawing, and bracing later, and he had a custom rack that fit his components perfectly. Should he need to adjust things in the future for a taller or shorter component he can swap out the existing legs with new ones made from the left over scrap.
