Hi KC,

Just some linkies for you which may help.

Some 'suggested' system builds
'Dream machine'
'Gaming Machine'

From looking at the dream machines, I note that they tend to cap out at 750W similar to what you are suggesting but I don't see any dual GCards. If you are concerned, I go to this linky all the time as it has a great power supply calculator.

Ram - I did notice that you are only going for 4g of ram? Not going with a 64bit Vista/XP OS? In regards to corsair ram, I have a matched set in my main box (don't ask the price...) - never had a problem and I can really squeeze it when overclocking - a point to note as well, if you have problems with your ram or have any questions, the corsair website is a great place to post and all queries are answered very quickly (go there on the odd occasion to see just how far I can OC)

PS - Also I noted you are going the corsair PS - I personally don't know the 750TX but I have used many 520HX/620HX and I cannot speak more highly of them - seriously, the corsair PS's are fantastic in both presentation (boxing / wires / parts) and in performance - very smooth (no, I don't work for corsair but I am a fanboi!)

Case - tbth, do a stack of research, your going to be putting a huge wad of cash into your box so the longer it lasts the better - the dream machine linky has some suggestions which you can click on to get details

Cooling - same as the dream machine, heard some great reports re the Thermaltake BigTyp 120 - just make sure you can fit the sucker in the case!

CPU - Dual core quad cores...and here respectfully, I think it is too early to bother trying to aim for a dual quad yet - it's still all very new stuff and I am positive the price will be unrealistic...

HDD - I honestly can't comment on the usefulness of so many HHDs...
