Dell's small business page offers desktops, notebooks, servers, storage, networking, and peripherals. Dell also has educational discounts. This page also provides a link to the Dell Foundation. The Foundation makes cash and in-kind contributions, especially with youth issues. And Dell has a good Employee Giving Program and Volunteerism project. If you are a nonprofit in Central Texas, especially the Round Rock area, Dell is a great resource for funding, equipment and volunteers.
