You may be right mcdermd, I seem to be having luck - I installed more modules of better quality DDR2 RAM I had lying around; in this case some 1GB DDR2-800 modules that came from a faulty Dell XPS tower. 4 x 1GB in total, in the right slot placement (inside to out configuration). I should also note that the additional power cable going to the 7800GT was disconnected, now back in.
Much to my delight, I'm now able to boot off the 10.5 installer DVD; both processors are detected, it passes all the basic system tests according to system profiler. I'm now downloading the Apple Hardware Test for it (2.6.3) to confirm that more components are working. I don't have any SATA hard disks to install OS X so will have to swipe one from somewhere (my wife's iMac G5 2.1Ghz recently got my 1TB drive that I wasn't using in my NAS, huge overkill but won't be opening that machine up again - I'll have to look elsewhere!).
Of note, the fans are very noisy and ramp up in speed after a few minutes, I can only assume that this due to them overcompensating for the LCS. I can't trust the LCS as it's obviously never been touched. The Delphi LCS even looks DIY with all the crappy cables and connectors, Apple really were pushing it
I do have an interest in PC watercooling so will hopefully able to rebuild the unit neatly and give this beast a new life!
I never thought I'd be lucky enough to have a Quad in my collection. Obviously it needs some TLC and is mostly stripped down, but with time I should be able to make it a really nice Mac to use.
