Here are places I have purchased various hardware from, with no issues:
www.newegg.com
www.mwave.com
www.zipzoomfly.com
www.clubit.com
Or, if you are close enough to this store -
http://www.pcclub.com/stores_info.cfm?stid=NVRN - it is a computer-only store, and their techs should be able to help you find compatible RAM
Whichever option you do go for, don't forget to run a memory test after installing (my favorite program -
http://www.memtest86.com/).
Hope that helps, buddy
