Yeh I'm quite enjoying using it actually... posting this from it in fact. I still havent worked out exactly what it's affliction to the R7k or the properly working Rage128 is yet, but it is functioning fine witha TT in it so that suits me fine. I ended up tossing in the G3/400-1Mb Sonnet card this afternoon before work and it is still a little sluggish but noticably more fluid than with the 200MP card in it... There is also a good chance I am suffering Porsche-Syndrome going back to an old world PowerPC and G3 after using the G5 for so long. lol... I do still beleive there is some performance to be gained from cleaning up the system a little, as I beleive there is a bit of bloat in it. Also a properly functioning ATI card should probably bump the fluidity in a better direction. 
But yes they were always a machine I lusted over in my early teens but I had only ever seen them in product brochures, advertising spreads and columns in MacAddict mag etc... Never once even saw one in the flesh until I bought this beastie. I remember there being a full page ad for the various Mac power-towers in one mag where it had I beleive the 6500, 8600, and 9600 all lined up and even on paper it looked impressive, as did the specs at the time. I'm definitely pleased to finally own one after nearly 20 years, and a MP example at that. I wouldn't mind getting a second one and running one as a stock configuration MP for posterity and the other souped up to the nines just to say I did.
In relation to another point you make, I like you, I have actually made a quite good friend out of what was a simple transaction. I have kept in regular contact with the guy in Canberra I bought this and the IIvx off (a not overly active member of the forums) and he is a top fellow and every bit as passionate about his vintage Mac hobby as I am. He actually sent me some extra goodies just last week to acompanmy the machines, which was a gesture I very much appreciated. I spent a good few hours at his place playing Mac's and intend to fit the fellow into my usual social rounds on my periodic Canberra trips from here onwards.
