I thought I had cleared that up earlier, but I'll try again.

I want a fast graphics and video editing machine. I've never played a computer game, don't plan to start now.

I'd like it to be somewhat "futureproofed" without going into a multi thousand $ bleeding edge processor. i.e., I'd like the *option* to be able to add more memory at some point.;-)
A while ago, Dan said he'd get a list together for me. That's what I'm waiting for. I figure a person that does that for a living isn't going to stick me with non-compatible parts.
The memory I bought I'll send back since I would like 4G sticks. I'll hold onto the PSU for the time being, until I am directed on exactly what I need.
The only thing that I've bought so far that I'll keep are 2X 1T HDD's and a copy of Windows Vista Ultimate 64 bit.

Going piecemeal like you are you may find out that you have a lot of non compatible parts that you will end up with as 'extras' that won't work together (been there done that).
The first thing to decide on is: What do I want this new computer for? You will find out that a fast multi-processor file server is not a good gaming machine and vise-versa. If you want an "all around does everything" machine, you may need to make a lot of compromises. The further you go in one direction the less performance you may receive in another direction.
