I was in need of an instrument rack to hold all of my music equipment, however I was not willing to pay about £60 for one. I discovered the IKEA LACK rack, made from a coffee table. On going to IKEA to buy one, I was a bit disappointed as the LACK coffee table is very big for what I need, and also the construction quality is rubbish - the legs are made from a honeycomb cardboard structure and are very flimsy. However later on I saw the RAST bedside table. Upon measuring it, I was very happy to discover it was 19 inches inside - the exact dimension for rack mount gear. I bought one and took it home to find it was perfect for a rack. It is made of solid pine wood so it is very sturdy, but also attractive. There is also a very handy shelf on the top to put other bits of gear such as mixers, drum machines or effect boxes.
You can stain or paint it as you like. Unmodified, it can only hold 6 rack units, but if you lower the shelf, you can hold up to 8. The final cost of this project is about £25.
