Hmmm it takes 30 seconds to do it yourself,and if we can believe your tag line....well.....

shut off the machine
put down a nice soft towel.
put the machine on the towel upside down
take out the 4 black screws on the middle front panel.
You should see the hard drives underneath them.
In the back corner on the same side as the optical drives there is a pretty silver retaining screw. Remove it.
Use your finger to push out the top (really the bottom) drive.
Put the new drive in the same way the other one came out.
Seat it firmly.
Replace the retaining screw, the cover, and the four black screws.
Fire that hummer back up and go!
no lines, no waiting

Good CyberP! Glad to hear it I played the first part of oblivion to get the feel of it before the machine went back. Niiiiice. (the dead pixel glared like a red demon's eye the whole time though so I'm glad I sent it back)
