I found one for sale for 300$, broken disc drive. I went to try it out and i couldnt seem to do anything with it, youtube shuts off safari (works if java is turned on but i cant watch videos anyway), all sites seem disproportioned and assorted oddly. Could I upgrade it to Leopard from my leopard CD that came with my 13'' uni (which was stolen)? Is the price too steep? I dont need a heavy duty machine, just something that will run fine.
