Wow, that's great, thanks guys
I've really been thinking about what kind of rad would be best to go passive with, so I went out and got some 1/2" copper tubing, thinking to do something like
this guy, but then I saw
this dude's rad, which also looked sweet. I think it may be a) more efficient, and b) a little safer to buy a new car rad, though, so I'm checking ebay
I'm leaning more toward the spiky one, though, just as a temporary solution ($10 on copper tubing for a passive, FANLESS rad is <b>much</b> better than $30 on a fanned H/C, to me)
Sorry, thread jacking, lon, I hope you got your answer and'll forgive me
