Just a quick snapshot, using my old sony ericsson camera
Desk is made from MDF, easy and simple to make, my dad made mine, cost £23 from BandQ and still have a huge piece left in the shed to be made into a smaller desk for drawing etc.
Monitor is only a small but nifty 18.5" (maybe 19" not sure) Acer X193HQ, came with my computer, no hdmi, but tower has a hdmi slot, :|, reason im wanting a new monitor
. Speaker system is from OcUK, cost me £55 + £6 postage back in may -

Sub is underneath my desk and then all speakers on the desk, not ideal, but no where behind me to put them to make properly 5.1, still, i like it
EDIT: sorry for the quality
