How old your main pc is?

[Katilian]

Depends how you classify my "main" pc. My newest PC is only 3 months old, but it gets less use (though works a lot harder) than my HTPC/Data Centre/Secondary Gaming PC which is around 3 years old now. I also have a laptop which would be around 4 years old now which probably sees almost as much use as my new PC.

So take your pick.
