[Kipper]

Not more than a couple of years. I only put the PC together in 2009 and I've replaced both PSU's since.

The Jeantech one was all I could get hold of at no-notice because I had work to do and the one I had blew, so I had to go out and buy one off-the-shelf instead of having the luxury of choosing online and waiting for delivery.

The BeQuiet one is newer, my server doesn't need the extra wattage, I just added it to try and cut down on fan noise (with limited success - but I now think the cases themselves are responsible for the noise, or at least not reducing it).

If stuff has to be swapped/replaced, then so be it - like I said, I'm not working to a specific budget, obviously I'd like to re-use as much as possible and spend sensibly - I won't go out and buy the latest, greatest kit but at the same time, I'm not going to buy something that's only good for another 6 months. I'd like to get another 3 years or so out of the PC before I start to think about a completely new system.
