What good is there to do with a server if you don't need one?
 

Anyone have a dedicated but not using anywhere near it's total amount of resources?

Is there anything to do with it to make better use of all the left over space/bandwidth/etc?

yeah do whatever you are using part of the resources on, again

if you have to ask...

why don't you downgrade to shared hosting or a VPS and save some money if you're not using the server?

seti @ home! :)

LOL wasn't sure what you meant so I looked it up. Interesting.

Isn't there some site or w/e that lets you offer your computer resources to help science or some shit?
