The main issue is cost-effectiveness with a 7 yr old system.
I went out and bought my son a nice Dell desktop system for under $400.
My daughter has an E-Machine and it works great.
When you're getting to the point where you may have to spend $150 or more on an old system, then it's better to go ahead an upgrade to a new system any more.
