I have done lots of fine pitch SMT hand assembly at home with stencils etc. But I do see this has lots of BGA chips and I'm not sure how easy those are (I've never done them).

BGA seems scary, but it’s not bad: with the proper amount of solder it “self-aligns” just like any other SMD component. Even a little more precisely because of all the contact points.

AFAIK, reflowing a BGA chip without fucking it up is difficult without a temperature-controlled reflow station.

Soldering BGA is the easiest part, You just need good hotair. While soldering connectors are hardest. They melt , do not self alging and many other problems

Yeah, reflowing BGA is a whole different beast. You have to completely remove and reapply all solder but then that’s not really “reflowing” that’s just assembling.
