Usage is mainly for gaming, mostly along the lines of CS 1.6 and Warcraft III. I'd like the cost to be minimal, just to replace my Dimension 3000. smile.gif Any improvements (price or value) is appreciated.

All of your links are broken.  :'(

On a side note,  I think I have the exact same case as the one you're getting.  It's right next to me in my "potential" computer, pile of parts.  :-\
