It is alive :slayer:
Although took me some time to get around to it

but I needed it done before the end of my tax year, 31st March
Will give extended specs and pics later on, but I ended up going with:
Asus Rampage II Extreme X58 Republic of Gamers mobo
6GB Corsair Dominator DDR3 Triple memory stuff
Intel i7 920 cooled with a 'true black' thermalright ultra-120 xtreme
ATI 4870 X2 :yum:
A fair few case fans in there, 2 opticals, 3 HDDs, card reader - still want another fan I reckon, plus need to sort out cables once I am happy with it all
It is running sweet so far, on Vista Ultimate 64 bit - had no issues with the software I need to run.
Oh, and Flight Sim X looks and plays phenomenally! All I need to do now is buy a 2nd 24" monitor

[I have one now as my main, buy my 2nd is only a lowly 15"]
