I must ring SCL too, I like the look of those all in one PCs, they are my prefered type of PC at the moment. Less to move around, less cables and less for the kids to fiddle with! Currently getting quotes for new PCs for 1 of my ICT suites. Hopeing to do a second one later in the year, but it depends how much quotes for revamping the servers and backend of the system come in at.
I like the layout of your room ICT_GUY, lots of space in there which is always a plus. Unfortunitely I will be stuck with horrible benches in lines which were installed years ago, there just isn't the budget to change them.
