Thank you both for your replies,
Both are encouraging :D. I like to think I'm not stubborn and really am ultimately just looking for the best way to do this project. I don't pretend to know all the answers :D. But if you ever need tips on building a box I'm your man! LOL
As far as the position of the fan and the baffles this is the design that I had begun to switch to. (just didn't finish the model)

So a single baffle with that box roughly 6" square (still need to work that exact measurement).
I agree that these fans would function fine and serve the purpose with just a simple on/off and temperature monitor. Which is really all I am after. @INTP Are you suggesting to get away from the Arduino idea or just saying that I could build a very simple Arduino that would display the temp on and LCD and power the fans?
@MorganS I completely understand where you are going with the idea of just using the server to power and cool the cabinet. I haven't ruled this thought out but I do also like the idea of just having a separate unit for the fans as well.
It is definitely a waste to run these fans 24/7. The plan would be just about 8 hours a day. Basically when I am working.
Hopefully this gets us somewhere :D. But yes you both are on point! And I would love to hear more input so I can move this out to the wood shop!
Thanks,
Kevin
