I am thinking about getting a new computer, but I haven't looked around for five years(!). So, I have a "rough outline" but if something doesn't look right, please tell me!

3.6 GigaHertz processor
250 GB Hard Drive
DVD RW
100 GB Ram

And I was thinking about getting a server, but I have no clue what I should look for...but specifically something along the lines of several gigs bandwidth and at least half a gig of space. Could I have an external server?

But as for the specs of my "ideal computer" how does it look?
