The samsung spinpoint 500gb is a SATA drive, and my primary drive. TBH, i have no idea how long the sata cables are, but they were PLENTY long, it kind of depends on where the sata ports are on your motherboard, but mine were almost in the bottom right corner, very close to the bottom HD's. The other HD is a WD 120gb IDE ( although I ordered a SATA, but they gave me an IDE which I never really noticed ) and I think it runs a little warmer, like 33-35c, but that's it. And no sata optical drives, really hate those IDE cables, but I have to do with them for now. But I wouldn't worry about those cable lenghts coz I've never seen people complain about them.
