well, rocked up at a client site this arvo - it's a deli.
the dell was right under the biltong chipper, after a bit of a clean up with an air duster, I'm still left with this:::
I'm quite impressed that it's lasted almost 4 years in these circumstances, but I think the hard drive is a lost cause (an error pops up saying teh hard drive doesn't match teh expected parameters) so I'll be amused/scared to see what the insides of the machine look like!
