I saw this thingummy whilst trolling engadget today.  I think they pulled it off of a 1982 Firebird.  You know, the sweet 6-banger one.  (Side note: bless these times where we can have horsepower with reasonable fuel efficiency.  I had a sweet station wagon with a 350 V8 that got about 18 mpg and had maybe 200 hp.)  Anyway, I guess size matters when you’re talking cooling area.  Does it ever reach a point, though, when you realize you’ve gone too far?  For example, when your video card won’t fit anymore, and your case is bigger than your bed?
