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.

I just bought a Dell comp 3 years ago and stuck a Radeon HD 2600XT in it.....I'm in need of new comp.

main is less than a month...

my laptop that fried in Dec was 18 months old and the other PC I have dates from June 2003 (was my main before).

About 4 years now the selfbuilt, but Im on my laptop more.

My retired PC has to be about 7 or 8 years old. I just use the laptop (a little over a year old) now.

The PC I'm currently using was build at the end of 2003. So it's over 6 years old. Since I have a 360 I'm not so much in need of a new computer. But it's running quite slowly nowadays. When the new generation of consoles is announced I'll probably buy a new gaming PC, since consoles are too expensive (imho) in their first year and have a small game library.

I'll try to dig out the details but no promises. It was a long time ago.

Basically I used a low power PSU and all in one MB coupled with a Low Energy AMD x2 chip.

The heatsink is a monster over the chip. About 6 inches high and 4 inches square at the base.

Lots of fins and copper pipes is the order of the day. It came with a big clip on fan but after a little experimentation I ditched it as the idle temp on the busy core #1 was 38C and even under load (not what my PC was designed for so no really a huge consideration) 52C

So now I have a whisper quiet PC and I recently upgraded to a Green Spin 1TB drive to further its low energy footprint.

custom built 3 years old and still running strong.

Thankies!
