u have one problem with 140mm.... the limited selection in fans.

And i dont think the overall increase from a 120 to 140 at the cost of better fan selection is gonna give u much of a win.

Id rather be on a 120 version with awesome fans, then a 140 with average fans. :P

And i agree with alex... 78 dollars in additional cost will net u better cooling in something.

At the very least, its dinner with girlfriend/wife so she can stop nagging u when you buy more computer parts.
