That was a part of my setup about a year ago. It also doesn’t include a small box I had with smaller electronics, two keyboards, three mobile phones, two Arduino kits, a Raspberry Pi kit, a soldering kit, a printer, Xbee wifi kits and a lot of cables.
A bit after that I have another 21″ monitor – I’ve moved houses since that photo was taken so my desk was a lot bigger.
Edit: I’ve since moved and have shed quiet a bit of gear including giving away a few laptops. But the really light 19″ monitor is great for hauling around – if only it was foldable though..
