Well, it depends what you call a modern computer. Yes, i know that
they have PSUs with 350 and 400 watts, but they are usually not loaded
completely. What i had tested was my previous PC with Athlon XP 1600+
- that's not so old.
About making room hot - in summer few electric devices can really make
my room noticeably warmer. It's because of bad ventilation, and
massive walls.. usually my room is cooler than outside. And i noticed
this by using the same Athlon XP 1600+ which i measured.
I will try to make measurements for my new Athlon 64 5000+
