My desktop doesn't mine. The 100 or so Mh/s I would gain would be pointless. I don't game enough that buying a high end card makes any sense at all.
To be honest, until you mentioned it, I didn't realize there was such a thing as rear blower fans. Obviously they wouldn't be a good choice if heat was an issue.
I am thinking of grabbing one of these
Zalman 12 Plus cases. Its not a top of the line case, but fits within my budget while having to buy a new card.
Any thoughts?
