make quality servers.
I've used Dell, I've used Compaq. Personally I liked the last Dell I set up. If you need huge servers with lots of expandability, Compaq may have an edge, but that doesn't sound like the case.
I would personally stay awayfrom white boxes unless you are a hardware geek - with one of the top 5 you get a known entity, with a white box you may get both got product and good service, or you may get one or the other, or neither. Even if you are a geek, and you spec every part yourself, will the vendor of that custom box come out to your office within 24 hours of a failure?
You have to think more about your requirements. Do you need disk redundancy?
How big are your disk requirements going to get over the life of the server?
How often do I need a backup?
How much data will I backup?
Whats the impact if the server goes down?
Answer these questions and you can start to build a server spec.
