So after running the auto tune on the PID it is holding the temp within a degree so I think that is very acceptable
I ran it for several hours set at 134F and it stayed at that temp. Every time I checked on it the temp was exactly 134F.
I also took a dead power supply for a computer that I had sitting around and removed the guts to use for a case. May not look that great but it will work well for a housing...
