OEM build, Can be activated once or something.
Whats the catch?
I cant change hardware in my machine? if i upgrade my PC it becomes invalid?
You can change the hardware in your machine however if you make a significant change such as a hard drive and motherboard, Windows will assume you're using a new PC and thus ask you to activate it again.
(Motherboard changes alone can cause re-activation, but a lot of the time its more if you change both)

Edit : As far as i know i can't buy OEM edition because its locked to your pc, if i upgrade a bit of hardware it break the license agreement.
No, you won't break the license agreement.
The limitations of the OEM license are that you can't transfer it between your machines - that is you can't decide you want to take it off a machine and put it on another - it needs to stay on the same machine. (This is the same as the Windows XP OEM License)
For this reason I'd say they only allow 1 activation (well, you said they do - I just haven't confirmed this yet).
If you do end up changing your motherboard or other significant hardware components and you're asked to activate Windows again then you can ring up Microsoft, explain what you've done and they'll do the activation for you manually.
Hope that clears things up for you (unlike the other posts in this thread which are completely off topic) and if you have any further questions, just ask them here and I'll get back to you.
