I've had a perfectly servicable desk but trying to run that and my PC on a small stand behind it wasn't working well. No real flow for me.
Ten months on and I finally got access to a larger space and was able to put new units it. So now there's 3.6m of nerd wall and it's all mine!
One space for computer, one space for painting station - and sufficient wiggle room that my daughter can pull up a chair alongside me when she wants to paint as well. I got to pull the 5.1 surround out of storage and hook that up too. Very exciting.
