Not sure what you are trying to build but this is what I would look when buying some MB for OS X.
- SATA Controller should support AHCI, it will make setup painless and will give you great speeds.
- If you need IDE support better to go with JMicron IDE chipsets, other IDE controller can be troublesome or slow.
- Look if the other integrated controllers (Network, Firewire) in the motherboard are supported or if you can make them work easily.
- If you going to use the onboard graphics on the MB make sure its supported, as just very few are.
- DVD-R/RW doesnt matter, they all behave the same. SATA or IDE doesnt matter as long as the respective controllers are working.
