RE: Heating the Prusa enclosure
I used my Prusa i3 MK3S+ in a room with temperatures around 10°C. I print PETG. Untile 1 month ago I had to heat the whole room to >13°C to get rid of the minTemp.
Now I use a Original Prusa Enclosure. I heat the enclosure up with a hairdryer. 1-2 minutes are enough. Then the printer can be deblocked. I switch on the preheating PETG and take out the haidryer. Later the printing process heates up the inside of the enclosure until 24°C.
And I have less problems with stringing (the box is not the only reason, friends help to improve printer settings..

Thank you for sharing!
RE: Heating the Prusa enclosure
You do not need to get to 90C. Quality is great at 40 C.
For what it's worth, the new Bambu H2D has a heated chamber which goes up to 65C. There's a Youtube video of someone taking it apart, and there doesn't appear to be any special cooling hardware for the motors or electronics.
Also, it looks like someone has been working on a chamber heater for the XL, but it hasn't been updated in a while. Though it could serve as inspiration for anyone else looking to develop something like that:

Plus there's this "Project Mastodon" thing to upgrade the extruder cooling fans, which would likely be a must-have for an XL with active chamber heating:

I've been considering getting an XL, but if I did I'd want to add a heated chamber for polycarbonate.
