Hhmm... I wrote that I would explain my investigations and what I learned from it further but failed to do so... the posting was already long so didn't do it... but I will in this follow up post... first a remark about my picture request... I am mostly interested in your face and how you look it... now onto the investigation report:
In short:
In 2008 my system/dream pc was acting weird, it was still using the chieftec case... the weird behaviour was probably caused by a defect memory chip... I didn't know at the time... I wasn't happy with the chieftec case... it was humming and was too hot for my liking... so I replaced it with the antec
1200... also removed one graphics cards after a few days or so... two months later or so I discovered the bad memory chip and rma-ed it... and got two new ones for free from corsair.
The same motherboard that I suspected of being fried was still being used... this surprised me today... it had the "burn" marks back in 2008, so it might have been burned by the chieftec case as well... for now I will assume the "shock" from the receiver caused it to die... I also found a little hair on it while it was on my table... but I suspect that hair land on it after I assembled it... hairs can cause system failures... but I don't think this is the case of it... perhaps I will test later to be sure...
Conclusion:
So far there is no real hard evidence that heat caused any deaths at all, it could all be electro-shock related, your system which must be running very hot could be further prove of this that heat inside a pc does not necessarily have to be a bad thing.
However the gigaworks s750 sound system died as well, could also be shock-related, however an electronics repair dude says it could also be heat related.
For now the main difference with my previous systems is much more heat and especially the receiver/second high power device attached to it... my previous pc's did not have a receiver attached to them... nor a gigaworks... so this new sound system situation could have lead to these deaths.
Therefore it seems wise to replace wall power sockets with grounded wall sockets, hopefully that will not cause new issue's... I have already read that it can... I have to read up on those potential issue's... one issue is "ground loop" ?
So I am not ready yet to replace wall sockets... first I have to read up onto potential disadventages and risks ;)
So far it seems to at least be a more safe idea for me/humans to have grounded wall power sockets.
(Perhaps what's good/safe for humans is also safe for electronics ! ;) =D)
