Sounds good SRS.

My system is a replace/upgrade bits as and when PC. I think the mouse is my oldest surviving component going back to when I had a 486. The case would be the next oldest, dating from when it was an AMD K2 500Mhz job. It's currently an Athlon 1Ghz. The newest part is the monitor which replaced the one I had when it was a P133 around the start of this year...
