I generally keep all of my computers. I have an extensive computing collection going back to the mid 90s; 1ghz slot cpus, super socket 7 boards, 3dfx cards, a handful of ISA soundblasters, etc.

When I buy a piece of computer hardware I try to think of how it will be perceived in the future for someone whose loves these devices. For example I just retired my main desktop with a 2600k with the original GTX Titan. It’s packed away and I may bring it out someday to make a powerful windows XP rig.
