Lifehacker reader Nathan didn't let the space demands of a growing family (and a large number of PCs) cramp his style -- he converted the linen cupboard into an office.
We've featured variations on this idea before, but the ability to store the chair as well makes this one particularly appealing. Within the cupboard, there's three PCs, a Playstation, a 24-inch Dell monitor, Bose speakers and a Canon photo printer. As well as saving space, it's also out of reach of any sticky little fingers. Nice work Nathan!
