Welcome to Apple Discussions.
Your iMac G5 1.8 GHz will support either Tiger (10.4.11) or Leopard (OS X 10.5.8). The latest Mac OS is Snow Leopard (OS X 10.6.4) but you need a computer with an Intel processor to run it.
I would begin by upgrading RAM. Your computer will support up to 2 GB of 184-pin PC-3200 (400MHz) DDR SDRAM in 2 slots. That will give you plenty of juice to run either Tiger or Leopard. If you opt for Leopard you should keep in mind that Leopard takes up 9 GB of HDD capacity just for the OS. You also need to maintain a minimum of 15% of total disk capacity as contiguous free space. In any event, a HDD upgrade to a larger capacity HDD will improve performance of either Tiger or Leopard.
Please do post back if you have further questions/comments.
Any suggestions reference good HDDs?
I am not up on iMac hardware issues, but here is a list of available HDDs for your computer at OWC. There is quite a range of them. You might want to post in the the iMac G5 forum for more specific recommendations.
