Thanks for the crits alltaken.
Good point about the chair legs, im looking for a design of frame that will give a free standing look, hence the position. Still experimenting with various alternatives.
Although you cant tell from the pic, the keyboard/mouse are seperate from the right-hand side section and would be hieght adjustable along the frame.
The reason for the extra bit of the top is im considering mounting some from of lighting or a shelf for webcameras.
The screen and keyboard would be intergrated, everything else will be modular, therefore interchangeable racks would be a good possiblilty.
Im currently 3 weeks into my final year, still very much in the research stage, the project doesnt end until the end of year, so a long way to go.
