Thanks for your anwsers first
I also found a old Thread about exactly the same topic:
Their conclusion was the same: It WILL destroy the PC and all your spend money go‘s brrrrrr
But everybody said, that it will distroy the PC over time ... so can I use something to automaticly clean the water? Someone cleaned it before, so ... is it possable to build a ‚water cleaning loop‘, running all the time, makeing sure the components won‘t short?
Or would that be as stupid as my last idea? XD
