Did you get the desk and the shelves at IKEA? If not where? I really like them!
All IKEA...the desk is bit of a recycling job. The lower part is a computer table they used to sell, then the part with the monitor/speakers on it is part of my old IKEA TV stand (which wouldn't hold my current TV) with a set of legs. You could probably make a similar combination today with a rectangular tabletop with the Vika Curry legs and a smaller oblong tabletop on some adjustable legs.
The shelves are part of the Norrebo storage system.
