Do you ever turn off your pc/laptop and...

I've had my server 2003 fileserv running for about 4 years straight. Only time it ever goes off is for a quick dust off then it's back to work.

That's the key to long lasting equipment. Dust it.

exactly. I've a server 2003 running torrents and all forms of P2P, and other services, and i only shut it down for my yearly clean-up (besides the OS updates, but those don't count). It has a lot of fans inside and it's quite refrigerated..
It's a AMD Duron 1300, with 1Gb ram and 8 HDD, in a total of 750gb (ye, lots of older smaller HDD inside). It has only the power cable and the RJ45 cable plugged

At university, it was on 24/7. Once I started having to pay my own electric bill, I got into the habit of turning it off when I'm asleep or at work.

From what I've read, the most likely thing to fail is the hard drive and their life spans decrease with each power cycle so keeping them on means they're less likely to die on you.

Mine's always on, unless the power goes out.
