Hi Tanggy,
I like your design 3 and may want to copy it for my new tank
There are a few questions that I need to ask:
1)Will the chiller be able to keep inside the cabinet? as I understand it give out lot of heat.
2)So far have you come across any members using this design?
3)Will this design work?
I really like this design as it lookneat and CEO do not like machine lying on floor
