Looking for a new computer desk for my work/gaming PC. Would like one with a shelf for the machine (so it is raised off the floor, preferably without a back so there is room for air to flow), room for a 23" Monitor and plenty for room for Keyboard and Mouse, plus writing space. Got a budget of between £50-£70. Looked on the likes of Ikea, Asda, Tesco, Amazon, Staples and Argos, but not found anything that really stands out. Any suggestions?
