Julian8127,

Using an OEM version usually works only on a manufacturered system. You will need the full version of Windows to install, since this is a custom machine.

Then why does it say "for system builders". I think you just confused me more ~_~

Julian8127,

After reading the info from NewEgg, I would call MS and ask them before I paid $100 for something I couldn't legally use. 

Most OEMs I've heard of only offer software support for 30 -90 days, so you don't get much help there.

I would think, if you build your own copmputer you'll miss out on 30 days of software support and then be in the same situation as everyone else.

From Newegg for OEM version:

"This software is intended for pre-installation on a new personal computer for resale. This OEM System Builder Channel software requires the assembler to provide end user support for the Windows software and cannot be transferred to another computer once it is installed. To acquire Windows software with support provided by Microsoft please see our full package "Retail" product offerings."

You're paying less because software support is not included. Check what support MS provides with their Full version, I checked quickly and didn't find anything about what kind of support or for how long. You would be your own software support, If you know where to find free (various windows help websites) and professional (not free, local computer shop with tech) help if needed, MS even has some reference sites and a forum. You'll have to decide on your comfort level with doing this, of coarse, if MS says it's legal for you to buy a OEM version.

Hope this helps, a little,

Dave

Thanks for doing some research for me Dave. I think I made up my mind now on what I want to buy.
