Nothing too critical – just a few of the following are my thoughts..
The frame is NOT Yeti built, as 2000 saw Schwinn using their “N’lightened” aluminum design.. Also at this time they moved to an intergrated headset (not a fan.)
The frame itsself looks to be in good condition & needing paint…. If you have the time and energy to build it up – definately go for it.. Otherwise keep your eyes peeled to Ebay & Craigslist as the 17 inch frames seem to frequently come up for sale.
Me, I’m a bigger guy and have to work double hard to find the 21″ frames..
Good luck!
