I just bought a new iMac with Mac OS X 10.5 and I wanted to build my own external USB 2.0 DVD burner. I've heard that people have had problems, but I was wondering if anyone had any success with any specific drive? I'm trying not to spend too much. I was hoping to buy an internal drive and external case from Newegg.com. Problem is that it is very hard to find any Mac compatibility info. Any help is greatly appreciated.
