6' heat sink. Anybody know where to get one?

Also look into stevesleds.com he uses a heatsink tubing with forced air fans...another option..

Thanks Jonathon! I ended up getting a 60" and 30" from Steves and just cut and bracket it until I had 72". The fan was pretty cool cause it blows through the center of the tube HS and keeps it cool to the touch.
