If you don't go with Microsoft's Foundation Server (there is an entire thread on it from about six months ago), then around $3,000 is probably doable. Something I didn't see on your quote were the CALs. I am sure the server would come with 5 CALs, but then you would need to supply the CALs for the other computers. Of course, it could be cheaper to do user CALs.
Is Dell helping you put this together or are you configuring it yourself. It will likely be cheaper if the latter. Once you get what you want, post it here and let Indy and everyone take a look. Don't listen to me, I will likely add things on.
After you have a price, then go to Dell and ask them to knock it down 15% or so. I am sure they are making much more than that.
