i have decided to put in a design department in my office. We will be designing drawings for different Fire Sprinklers, Fire Alarms, Fire Suppression & Hood & Duct and we will be expanding as projects arouse. I am not sure on what type of computer or where to invest my money in a matter that i wont spend it wrong. I can go to the local Best Buy and pick up the most expensive desktop and it not fit my requirements for such business. I am looking on buying a complete set-up. 30" Screen & a powerful machine. Suggestions Needed Please!!
