If he takes the long view though, #1 is an excellent choice. Once he has a good ATA controller card, he can add new fast EIDE drives any time he wants, up to four devices total. An ATA card is one of the best upgrades a person can make on those old PCI Macs which lack IDE support and is also a pretty good option on the Beige G3. Even though the Beige G3 has built-in IDE it only provides 16 MB/s transfers (theoretical maximum).
My Umax S900 Frankenmac has an Acard 6280M, a 400 GB Seagate drive, a 40 GB IBM drive, a DVD-ROM drive and a Pioneer DVD-RW drive.
