What's beneficial about having a silent computer?

Check out this site: http://www.silent.se/

They sum it up better then me :)

Yeah stock cooling, although it's still really loud, and I couldn't work out what you're saying there, are you saying I need to replace my RAM? :/

Also, my dad doesn't really like overclocking, because he thinks the processor lifetime is affected, is that true?

Also, when surfing the internet like now, I use a really old Pentium III (800mhz!!!!) PC (which is my own one =[) that could do with some overclocking is it possible to overclock old machines like that. (For reference it has 256mb RAM, and an nVidia TNT2 Pro). Actually it should be faster, but XP Home edition doesn't support 2 processors =[ (as it is a Dell Workstation it has 2 PIIIs)

EDIT: yeah, I'll probs buy an 8800 when they come down in Price and Crysis is released  

I only clock my graphics card and only when it´s not to new anymore or if I read that it works fine from a reliable source, I also build my PC from scratch which issn´t really moding but some people are impressed anyway

Yeah the life span goes down from like 50 years to 15 years maybe... if you think you'll still be using the same CPU in 15 years think about what you were using as a PC 15 years ago?

 well I was 1, so errr...

that's good news then, never knew that CPU's could last 15years, let alone 50! and as we get through a PC about evry 4 years, well...
