Glass Computer Desk Size 90W x 62D x 89H cm Materials 5mm thickness of tempered glass Steel tube with silver powder coated.
These used to be £39.99 (and were a bargain then), and now they have reduced them to £29.99, maybe because they are discontinuing this line. It has a pull out keyboard shelf and a top shelf which I have put my monitor on, so the actual desk area is free, nice and spacious. I bought a couple of these and put them side by side - you don't have to attach the side holder for the PC tower if you don't have room for it, you also can't change which side the tower holder comes on the desk. The big plus is that they are very sturdy, as well as very nice looking - nothing cheap looking about them at all. I tried to order these online, but they have no more stock, but you can still ring around individual stores and some of them still have stock. I got mine at the Waterloo Ryman's and I know that Ryman's on the Strand have a couple, it's worth trying the larger stores.
You can see a photo of it here - it used to be available at Amazon - called Urban Glass Computer Workstation. http://shopping.kelkoo.co.uk/ss-glass-workstation.html
