[QUOTE="astrog21, post: 1771716, member: 395870"] My model does not have any removable cover like that, it's like the one in this guide: [URL="https://www.ifixit.com/Guide/iMac+G3+Model+M4984+RAM+Replacement/1500"]https://www.ifixit.com/Guide/iMac+G3+Model+M4984+RAM+Replacement/1500[/URL] The RAM is mounted on top of the motherboard, so unfortunately it necessary to slide out the entire motherboard from the computer housing. I think the removable oval cover came in later revisions? I have already pulled the motherboard tray out to re-align the disc drive (it was dislodged and therefore couldn't open) and can confirm that there is a metal shield screwed in place, blocking access to the CRT tube. Of course this can be unscrewed and removed, but I don't really want to have my "hair stand on end"! I found an eBay seller with a listing for a 128MB stick and free postage for less than $15, so I've bought that. It'd be awesome to have 512MB, but I don't really need that much to run Mac OS 9. If I need to I can always buy more RAM later. [/QUOTE]
