of course it's useful, but I'd be much more annoyed about 300grams of aluminium/copper landing on my $200 graphics card and blowing <i>that</i> up than my CPU frying when I can get a duron that'll probably perform better anyway for $30 to replace the nuked CPU. (as it's likely to be an old t-bird in a system of that age). And if it falls off in shipping god knows how much damage a large lump of metal rattling about inside the case is going to do 😱 ... the CPU would be the least of my worries.Some would, some would not, but it's still usefull!
