Thanks for the lengthy reponse.  Sorry I was pushy, I was trying to get the order in that day...So it turns out I got the Lite-On DVD Rom SOHD-16P9SBLK for $23.00.  I also got the DVD+/-RW NEC ND-3520A.  Also, what is your opinion on Samsung hdd's?  I ordered a SATA 120GB SP1213C hdd.  
Thanks again,
Derek
