I've seen somewhere where someone installed the transformer underneath the chassis plate. I think it looks nice and cleaner than having it up top and it saves me the trouble of painting the plates. I was wondering if there are many people who have done this and what the long term effect was, e.g. heat build up, component failure, etc.

There will be a lot of extra heat buildup, and the mounting hardware will have to be adjusted accordingly. We mount a similar PT-7 in the Tode guitar amp this way, but there's a lot of air space inside the Tode, and giant air vents just above where the transformer sits.
I'm not sure I understand what doesn't need to be painted by mounting it this way. The lamination stack is varnished already, and doesn't need to be painted.

I'd want to paint the lamination stack for aesthetic purposes. I wanted to know if there were any negative side effects from the extra heat from people who may have done this.

Painting the lam stack is very easy. Just wrap painters' tape around the terminals, pop the transformer on the ground without its cover and spray away.
Also, you'll likely run out of internal chassis height when you build the power supply on top of the transformer mounted in that manner.
