Windows 7

[Sindri]

I'm going to be building a computer from scratch and haven't got another copy of windows e.g xp/vista.

Will i be able to use this to install windows 7 on its own (OEM):

OR will i need the full retail version?

Thanks for your help guys, was slightly unsure as i used to just buy a prebuilt system and then upgrade them when they needed it so i always had the original disc to use.
