There is a very big difference between system from Signburst and off the shelf piece of junk consumer class PC from Best Buy with the same processor and amount of ram...... On one side you have a system built with top of the line components aimed at bullet proof business class reliability, no bloatware, a far better spec'd hard drive, components that are specifically benchmarked to work well together, cooling specifically selected to ensure absolute optimal performance, and built with performance specifically for our industry in mind. On the other side you have a system built with the cheapest possible, slowest crappiest components (2mb cache 5400 rpm hard drive junk motherboard with crap capacitors that will have a pretty short life, etc, etc), loaded and bogged down with a ton of crap that you do not want or need for a business, crippled bios, crippled expandability, proprietary parts, etc. The cheapo system is cheap for a reason.
