What is the Difference between OEM and Boxed Versions of Various Computer Products ?
This Answer has Two Perspectives --
2. For Hardware Products : OEM Versions are generally the same hardware but packed in bulk to reduce the packing and shipping cost by vendors. They are preferred if you are comfortable and understand what you are buying, sure of it's authenticity and have no doubt that the product is altered or fiddled with. There is no reason to buy a retail product when OEM is cheaper since you will be removing it's packaging and then installing it anyway. At the same time, if you doubt the originality of the product or if you do not trust the vendor, it is better that you go for Retail Box product only.
