Have received a few questions, here's the pics of what my mods look like

The blower is from
MPJA - Power Supply, Power Supplies, Security Cameras, LCD, Fans, Etc.. This is a 24volt unit that I power with a 6volt dc wall transformer with the wires fed thru the co2 tube opening. Note mpja has a min order amount. Everything is mounted to a 1x2 which is attached where 2 of the cooling plate screws are. Just add extra lenght to the screws to make up for wood thickness. The majority of the blower output (which is plenty even at the low voltage) is open blowing up the cooling plate, but it puts plenty of air up the copper pipe to cool the tower. I could not get a fan to do this. The pipe top opening is about 2" below the tower top and you can feel the return air coming out the bottom of the tower. The 33k ohm resistor works good in my unit. I suggest trying a bucket of water in the cooler first just to make sure it will work for you.
