Thanks for the replies, the cabinet turned out better then expected. For now I have decided to just keep it simple inside, didn't want to spend too much time because I'm not sure if I'll be keeping the JBL filter. I've got all the materials to arrange all the cables and stuff, but during the startup of the tank, I'm gonna keep it like this for easy access. The wood on the inside isn't painted on purpose, hopefully it will soak up any water should I get a leak inside. I'd rather change those parts then the entire cabinet. I also figured out why I still had a gap on the side with the door, I miscalculated the distance with the hinges...ah well, like Bob would say, We don't make mistakes, just happy little incidents! Yours is coming along really nice Piotr, can't wait to see the end result!
