TheI plan on starting an office from "scratch," so to speak. When doing so, it should be built using the most economic means possible. I plan on building all my computers from parts. Financially, I won't be spending money for additional components (or excessive components) I won't need. I would designate different computers for different things. That way, each computer can have the best version of the components and, more importantly, the programs needed to do each particular job (such as web design, content editing, or just writing)
Although computer forensics can recover files, and I would invest in a recover method, I don't want to depend solely upon computer forensics. Therefore, every computer in my office will be connected to a singular storage space on the web. Each design, file, etc. made for the development of the company would then be stored on the "cloud" as well. This way, I would have no fear of losing files and I will have an ideal office setup that will work at the start and allow the wiggle room my site and company will need to grow.
