Generally any ODD will do, you just want to make sure its internal and connects with SATA.
Komplett.no - Sony Optiarc DVD±RW Writer, AD-5280S
I like the Sony Optiarc line because of the plain black faceplate, keeps the front of your case looking classy.
Thats really strange, because it is the low-profile memory, at least compared to the other Corsair Vengeance.
It will fit just fine in your motherboard and case, the reason people usually get low-profile is so it will fit under aftermarket coolers.
