for the non-technicals in the group..

big ass = heatsinkusa.com with a major assist from UPS and Alcoa

Damn that many?? was thinking I could get away with 8

Forget about cxa3070

It's all about cxb now

15! googled them. that $350 - $400. a lot of $ to make ur own.

Since you have a square, 4x4 area, id go with either 9 or 16 cobs spaced evenly in a square pattern.

9@1050 would be cheaper but less efficient
16@500-700ma would be more expensive but much more efficient. Id go 16.

9 @ 1.4a = Around $600

I was referring to 3590's. Sorry i didnt include that.
