Re: Our office computer is Pentium 4 Willemate (spellcheck) 1.7 Ghz, 512 MB SDram
I'd say it's a good deal. If it's just for an office computer and not for gaming or anything then it will be plenty to get your work done.
Desktop: Dell Dimension E510, 2.5GB RAM, Intel P4 3.0GHZ, 250GB HDD, Windows Vista Premium. Might not be the best, but the old girl is still running good.
