Office Props - Computer Designs

Above are thumbnails for the computer design, I have chosen designs 1 and 3 to develop as I wanted a stereotypical computer design. 

I really like the bulky design of 3, I don't want it to look too high-tech as the scene needs to look quite dull. Below is the designs turnaround.

For the colour scheme for the computer I felt that the 3rd design would be the most realist colour but still work with the overall feel of the office. I will show lighting in the elevations.
