To save your confusion when people link license agreements and whatnot else, here's the 'summary':
* There's no difference whatsoever in the installation/feature set provided. They are different 'licenses', not different 'versions'. * The OEM System Builder license is much cheaper because it does not provide the same range of entitlements. * It is intended for use by 'System Builders' who assemble and preinstall systems for sale to customers. * Product support for the installation must be provided by the system builder, not by Microsoft. * The license can only ever legally be used on the initial system the license is 'assigned' to. (i.e. the system on which it was first installed/activated.
It is not supposed to be sold directly to end-users, for use on their own machines. However, if a vendor sells it to you regardless then the resulting installation will be a legitimately licensed one.
By the way. A 'motherboard upgrade' performed later on will effectively turn your machine into a 'new machine', and thus render the license void. If you wish to have a Windows license which is legitimately transferrable to a different computer later on you should instead pay the extra for a full retail license.
