Full Height Fish Cabinet Rust

[blackjack0512]

Hi,

I have recently purchase a full height fish tank cabinet. While cycling the water after a week, I noticed that there is a lot of condensation on the interior of the cabinet (that the top of the fish tank faced) and the nails/joints/hinges are rusting.

Just will like to check with you all whether is this normal? quite upset to see rusty stuffs within a week.

Tank might be leaking.

Is the rust dampness isolated to one area? Check there for leaks.
