Dangers of dismantling OLD microwave?

Ive searched for a while on the forum, and not finding exactly what I am looking for, figured I would ask. Is there anything "dangerous" in an OLD microwave? I know the magenatrons can have harmful stuff, so I am 100% not even going to touch the magnetron and just leave it where it is.

But I found a microwave that is old and weighs probably 100lbs. I took the covering off it, and cut out a few pounds of wire. And there is what looks like a 20lb transformer in there I want to get to, some circuit boards, transformers, electric motors (for a vent fan), and other bits.... I just wanted to check before digging into it further, if the magnetron is the only thing to look out for or if there is any other bits to avoid in there specifically in old, large microwaves.

I took out a massive capacitor too. I know that was dangerous and probably should have been more careful with that as it could still hold a charge.

I know the user eesakiwi has a few posts on this topic, but I am specifically wondering if the size or oldness might come into play, or have any more/different hazards. This is a hobby to me, and I am all about saftey. If there is even a remote chance of anything hazardous (other than scrapes and cuts from the metal on my arms that heal and come with scrapping of course ) , I dont want any part of it!
