Selecting parts for new build

In my case, i bought a mother board & an OEM licence at the same time and build my kit around that.
How does it works then...?
I had OEM XP & Vista and made once a multi boot on my new machine without problem (running only Seven now...)

I buy here in a shop OEM versions seperately at the condition to buy at least a computer element...

The motherboard is considered the heart of the computer so the license is tied to the motherboard. If you "upgrade" the motherboard, you need a new license. If the motherboard fails, and you replace it with a like (or very similar) motherboard as part of the "repair" action, you can use the same license. If you decide to "upgrade" the motherboard because the old one failed, then that requires a new license.

I know that many have upgraded and used the old license but that is not legal. And I also know that many have upgraded, and when they were forced to call MS to get re-authenticated, MS gave them a new key. But being able to do something does not make it legal.

Isn't it legal to unload Windows 7 on my old computer, removing the serial and then using it on the new build?

As I said, it is only legal if that copy of Windows 7 is a "retail" version. If it is an OEM or upgrade version, then, NO! It is not legal to use it on another computer. That's stealing and you would be a software thief. Please don't do that! I know most people think they paid for it, they should be able to do what they want with it, but they can't. That is not how software licensing works. And note this is not a Microsoft thing, it is a software industry thing. You don't own the software. You own a license to use it, and by using it, you agree to use it in accordance with the licensing. That is why it is called a EULA - end user license agreement. If you don't agree, go with one of the many capable and "free" Linux alternatives.

I might want to go with either 6 or 8GB instead

Understand that board has 4 memory slots and it supports dual-channel memory architecture. That means in order to take advantage of the benefits of dual-channel, you must use RAM in pairs. To get 6Gb on 4 slots (2 pairs) you would have to go 2 x 2Gb plus 1 x 2Gb. That would leave the second pair only half full. Or you could go 2 x 2Gb plus 2 x 1Gb. That would work, but then you have to make sure the 2Gb sticks are compatible with the 1Gb sticks. That's perfectly doable, but requires more homework before purchasing. That is why I suggested 8Gb so all 4 2Gb sticks could be the same.

As i said i will not know what exactly PSU it is before next week. I will let you know what one it is by that time

And as I said, be prepared to toss it. Note I would rather have a 500W Antec or Corsair (for example) PSU than a 600W off-brand.

Aha, thanks for the information i appreciate it.
I will go for 8GB of ram i think then
Also i will remember the windows OEM part, i wasnt aware you weren't allowed to do that. Good thing i have a retail version of Windows 7 Ultimate :)
