Copper Case (aprox 40kg). Need help.

Hey, after i saw that fully passive cooled pc (no fan, no water loops, pumps, etc!) on linustechtips video (not sure if i am allowed to post the link here.. just search it on youtube) , i decided to build one by myself.
Ok, the cpu, gpu, mobo chipset, ram memory will be cooled off. But my biggest consern is: does the rest of the parts from the mobo (like resistors) will survive in a completly fanless and sealed case?
From my experience, there are two probabilities:
1. Those parts will overheat and will burn.
2. They will warm up until they reach a temp and they just stay at that temperature without any damage.
So what do you think, people?

It’s all about how much heat you are moving from one area to another!
Latent heat stays put for example the heating in one room is 25C the case only produces 20C of heat the sensors of that computer case will show 25C.
Conversely if your copper pipes throw out 50C and the room is only 20C then dependent upon surface area and speed of being transferred it should be lower than 50C as this is equalising into the surrounding cooler air in the room.
To make this work without fans really depends upon the amount of heat produced over how much time this heat is generated and how hot is ambient temperatures.
I'm building a copper case, but in reality unless I attach a radiator the size of the case to itself the heat will be saturated and keep climbing unless I move it to another place! i.e. into a room with fans LOL.
I suggest the best way is to stick a radiator outside in shade so natural winds act as the fan winter is best for Ghetto cooling LOL

Thanks for answering. The only way to be sure i will not burn my pc, is to build the case (or atleast a part of it) and test it wit a scrap pc ( apparently i got one that collecting dust for years)..
I was thinking to build small heatsinks for every part of the mobo (litteraly, every chip, every resistor, every diode, etc) and then to put a heatpipe on all those heatsinks to transfer the heat to the case walls.
Here's my 3d prototype

I somewhat know him his studio is about 10 minutes from here he struck me as a pretty nice guy just doing his job. Granted his style isn't for everyone lol.

A good indicator for you is modern day motherboards that have lots of heat sinks and shielding unless you do some serious overclocking those stock caps and transistors should not over heat and heat always rises upwards!

As for Linus in that vid I found it weird he did the thermo imaging in open warehouse with lots of ventilation and to use HFC's to create semi phase liquid cooling to vapour and back again under little pressure is not new it’s not efficient. Shuttle’s heat pipe works like that, but a fan is needed due to limited surface area in getting rid of heat!
I can guess the inventor of that massive cool box owned 1980's amplifers which genraly had massive heat sinks to cool circuit boards for amps
