There's a whole section of these shelves in bunnings in different sizes. Mine was like $11 and I think 1.8m long. Then just chopped some wood block and nailed it on. Stilts at the side and back, and will be drilling holes in the back one for cords. I wanna paint the wood parts white at some point too. Oh and also I got a bit of felt with sticky-back on it, and just put chunks under the wood so it sits nicely against my desk top (found it in the shed) - but can probs find easily at bunnings too. I've never done any kind of DIY shit before and had zero clue wtf I was doing. Result is boss and perfect.
