    How do I get into this thing?
    Okay, I've got a problem.

    I'm trying to replace the hard drive on a G3 iMac. I've got the parts, I've got the instructions, it all looks fiddly but straightforward. But I'm falling at the first hurdle because I can't get the outer casing open. I've taken out all the screws, and the back is loose - the trouble is the hooks or clips or whatever they are inside the front of the machine, which are hanging on for dear life.

    I've seen a couple of youtube videos where the whole shell comes away with a gentle tug - mine doesn't. I've seen posts on forums advocating the judicious use of brute force - but I've gone as far down that route as I feel comfortable with too: I'd kinda like to be able to put the thing back together when I'm done.

    There must be something I'm doing wrong, but I don't know what. Help!

    Never opened one of these machines but a number of our members are very familiar with older Macs, so I'm confident you'll get help pretty soon.
    Hope everything works out for you.

    BTW: Welcome to the forum
    I've always wanted to be smart, handsome and modest. But, I guess I'll have to be satisfied with two out of three . . .

    If you've got the parts & you have the instructions...then there shouldn't be a problem. Maybe you don't have "good instructions". Go to iFixit.com and try their instructions:

    Installing iMac G3 Model M4984 Hard Drive - iFixit

    Good luck,

    Thanks for the goodwill, guys, but any guide that basically says "then simply remove the plastic casing" - and the iFixit one is the same - is no use to me. The front clips just aren't releasing.

    Assuming you have removed the screw under the handle on the back, you just may have to resort to a moderate amount of force to get it off.
    Just make SURE you have ALL the screws out.

    Okay, in the end brute force did the trick - sure enough, there was a pretty scary CRACK! when the cover finally came off, and one of the clip housings did break, but it was all plain sailing from there on in: disassembling and replacing the internal parts was a doddle, and the machine is now back up and running.

    Phew!

    Sometimes there's no substitute for getting a bigger hammer.

    Glad it worked out for you.

    If you are having issues opening it up I wouldn't advise making changes which if done wrong could break your computer.

    I would take this to a specialist repair shop and pay them to do it for you.
