It depends on what you're talking about, no problems with an OEM operating system like say WinXP, as long as you're absolutely positive you get the legitimate installation disk and a legal product key, but when it comes to OEM or bulk, internet purchases of DVDROM, CDRW, DVDRW, and things like that, sometimes you only get the drive and no software to go with it, now an OEM local purchase from a reputable computer dealer builder, is OK as long as you get everything you need software wise. I have a friend that ordered a CDRW OEM, through the internet, he got the CDRW, no software, no warranty, it was basically useless without the CDRWs burning software, and because it was an OEM purchase, the Sony corporation didn't give a rats a$$ about his problem, it took him almost 2 months to finally get his problem solved, and that my friend is a true story. So just be careful!
