HI!, im codmc123. i am building a computer and im choosing my parts from pcpartpicker.com. it says that there is no problems with all of my parts but i think that there is. my motherboard is the msi-g45 that supports 6 SATA ports right, and i am pretty sure that they are SATA III 6GBs. But it's my Optical Drive that seems to be the problem because it's interface is SATA 3GBs, all of them are! so what do I do? Are there no problems?
