text: If your clients are just serving up static websites, a Celeron will do. Go for the memory for sure.\n\nI agree that a Celeron is an odd choice for a professional server; but it really depends on your application. If your clients are just dentists who have websites with some cute photos and their telephone number, then a Celeron could provide hundreds of these clients just fine.\n\nIf your clients have any sort of server side processing (checkout carts; SQL-driven blogs; etc.), just pay the extra few bucks to get a better processor.
