It does, though getting it installed and bootable will take some 
finagling with Open Firmware.

It takes an ordinary 3.5" IDE drive. IIRC, the first-rev beige G3 
motherboards couldn't handle slave devices, so the hard drive was one 
master, the CD-ROM was the other, and that's all it could take on IDE. 
Mine has an internal SCSI Zip drive as well. There isn't room for much 
more than that.

Similar to old PC BIOSes, the root partition needs to come entirely with 
the first 8GB or so of the disk in order to be bootable.

I ran KDE 2.x on one of these machines a few years ago. The experience 
was not unreasonable.
