Is this worth buying used for a couple hundred bucks?

Beige MT G3/300
128 MB of RAM, 8 GB internal drive, internal CD-ROM, modem: none, includes keyboard and mouse, internal 100 MB Zip. I don't think any OS is on it. I can upgrade some of the componants.

Someone said its similar to a i386 machine with around 600mhz or so.

Thnx.
