OEM vs Retail Hardware
Many hardware manufacturers will sell the same components in both OEM and Retail versions. Retail hardware is intended to be sold to the end-user through retail channels, and will come fully packaged with manuals, accessories, software, etc. OEM stands for “original equipment manufacturer”; items labeled as such are intended to be sold in bulk for use by firms which integrate the components into their own products.

However, many online stores will offer OEM hardware at cheaper prices than the corresponding retail versions. You will usually receive such an item by itself in an anti-static bag. It may or may not come with a manual or a CD containing drivers. Warranties on OEM parts may often be shorter, and sometimes require you to obtain support through your vendor, rather than the manufacturer. OEM components are also sometimes specified differently than their retail counterparts, parts may be clocked slower, and ports or features may be missing.
