As you may or may not know, the 965 chipset no longer has native IDE support. Most manufacturers have put a 3rd party IDE controller chip on the board for backwards compatibility. All the ones I've seen have been made by JMicron. There seems to be a lot of issues cropping up with this. Because of this, I'm making the following recommendation for a 965 build: Go 100% SATA. There is no sense in buying a new IDE hard drive anyway. There are now enough SATA optical drives on the market to make this very viable. If you must reuse any old IDE drives, be aware that you may have problems with them. Now - what do I do with my old IDE hard drive that I wanted to reuse? Well, my suggestion is buy an external housing for it and use it as a backup device. Here is one I *highly* recommend: http://www.newegg.com/Product/Product.asp?Item=N82E16817155601 It's aluminum, it has a cooling fan, and comes with an OEM version of Acronis True Image. You can create compressed images of all your partitions with it - and the image and housing CAN be used for a "bare metal" restore to a new hard drive if yours fails. I would MUCH rather deal with this than RAID 1. Just hook it up and boot with the CD. The software can also be used to clone one hard drive to another.
