I'm in the process of putting together a new PC and intend to buy a copy of XP to go on it - looking around, it seems that some places offer the OEM version of the software (which as far as i've been told is the same as the non-OEM version?). On the basis that it's significantly cheaper than it's retail counterpart - i'd like to get a copy, but I notice the disclaimer on most sites states that it must be purchased with a "non-peripheral hardware component" (taken from eBuyer). Two questions:- 1. Is the OEM version the same as the retail version? 2. How strict are places like eBuyer on enforcing the clause, and what in their eyes constitutes "non-peripheral hardware"? RAM/Network card, or something more substantial like motherboard/processor? K.
