Of the Apple iMac G4 with the baseplate off - revealing four Torx 15 anti-tamper screwheads! the scredrivers are not onersouly expensive, asked a friend to borrow if he has one, but in both cases realising the recipient of my work may be a late or slow "payer" I am not proceeding without an advance to at least cover my costs!
Of the Dell M1210 when I have cracked the case (discovered the HD is dead, was fun though had to crack the password etc and it only just died during me recovering it!).
Hope they shell out - be criminal to let these not so old pieces of kit be junked for such relatively small system failures (esp. the iMac!).
