I've updated the page on G5 Tower Coolant Leaks with another reader's notes/info on DIY leak repairs (including O-ring part number/source) for those that can catch a leak early before it does major damage. (Unfortunately many didn't spot the leak until the PS, Logic board, etc. were damaged.) FYI - Updated at Noon eastern for replies to questions I had (Delphi vs Panasonic LCS, notes on different o-ring thickness/PNs, etc.)
