Western Digital is a good company. Also, I use GEIL value RAM, but you can overclock it quite a bit. Mine went form 400 MHz to 460 MHz or so. I'll show you the drives I have.
This one plays DVDs and CDs or whatever and is VERY quiet. You hear it rev up at the beginning, but then it is silent: http://www.newegg.com/Product/Produc...82E16827151212
This is one that plays, reads, and writes CDs and DVDs (+ and -). The only thing is that it is slightly loud when playing games, which is why I bought the quieter one also: http://www.newegg.com/Product/Produc...82E16827106965
