I am somewhat confused about SATA drives as I have never used one before. I am ordering a new computer with a WD 120GB 7200RPM SATA (OEM) and a MSI NForce3 250 K8N Neo Platinum Motherboard. So basically I'm wondering if it will install fine with the motherboard or are there other things I have to get so it will work. I'm just overall confused and if anyone could shed some light I would greatly appreciate it.
