|Like both the others have said there are more things to look at besides just price and space. |
You say you are not a gammer, ok what would it be used for? What do you actually need in a computer? Is this a long term investment or will you be buying another in a year or so (upgrade ability). Regardless I think the Dell is way over priced as well. If you are not the type of person to tear into and work on it your self what kind of warrenty and where can you have it fixed?
Practice makes perfect but only if you practice perfectly!
