I haven't figured out what to do with them. Never had one before so I thought they'd be interesting. They were pretty cheap so I took both in case I needed parts but they both seem to be fully functional.

They didn't come with drives so I stuck a single drive in one and 4 software raided in the other and installed 10.4. On the plus side, they both came with slot loading combo drives. I've started going through my Mac storage lockers so I'll hopefully find my server software. I may see if the 802.11n PCI card I have works in it. I'm sure it will with regular OSX but I'm wondering about OSX server.
