frantically looking for an adequate emoticon that would convey my complete and utter speechlessness

I am utterly, completely bowled over by all the support, encouragement and help here at the forum.

Guys, I really couldn't ask for more than the help you're already given me -  I mean, just the fact I got so much advice (and a new PSU hopefully being installed by the end of the month) is already beyond my abiliites to adequately express my thanks to everyone who took the time to nudge this Vue duckling toward the right pond.

As soon as the power-supply gets fitted in, I'll do a test render in PLE and see if everything goes well, fingers and toes crossed (if not, then it's time to take my old boy of a PC to a radical - and gradual - reconstructive surgery).
