I built an expensive computer
It cost me about £1500, I tried to get high end (but not ridiculous) hardware, built on a good solid base - decent but not excessive cooling to prolong the life of some of the components, a solid, hardwearing case to cop with knocks. That was three years ago, and barring any hardware failures, I expect to be able to have games playable on it for another three years at least.
