What CHIP are you wanting to replace? I hope not the CPU as that is not replaceable but soldered to the Logic board as is the Video.

Is that a 20" 2.1Ghz G5 iMac with the iSight camera? The Screws that hold the FRONT on by the RAM door are Torx. I can get you the size torx driver if you need that info. Inside are all Torx screws of different sizes.

Let us know what you are trying to replace. I have a complete service manual on that machine and own that G5 iMac also.

Also just to be sure, your iMac has the iSight Camera and is 2.1Ghz G5?

Will post that pic in a few.

Oh the memory cover. That has two screws, one at each end of the cover. The Memory is right behind that door/Cover. You do not have to take the machine apart. Let me find a picture and post it.

The screws are strange phillips type on mine but I used a small straight Jewelers driver and it works every time.

With a 2GB DDR2 Dim in that slot you will have 2.5GB RAM. Did it to mine and it really helped with all the apps that I run.

BE CAREFUL and not insert a driver in that one hole next to the center screw. That is the Ambient Light Sensor and you will damage it!!

Also if you have 1GB, There is 512 Megs soldered to the Logic board and another 512 MB in that slot behind the cover.

Ok here you go. Straight from the manual.

Tools
• Phillips #2 screwdriver
• ESD-safe workstation and mat
• Soft , clean towel or cloth
Preliminary Steps
Before you begin, lay the computer down so the panel is face down and the bottom is facing you.

Removing the Access Door
1. Raise the stand and use a Phillips #2 screwdriver, to loosen the two captive access door screws.
Warning: The ambient light sensor is located between the two screws, as shown in the graphic. Don’t mistake the ambient light sensor for a screw. Sticking a screw driver or other sharp object in the ambient light sensor could damage the computer.
2. Remove the access door.

Hi,
I have an Imac G5 PPC 2.1Ghz & I was wondering if I can convert it to Intel by replacing logic board. Can I use a motherboard I have from an Acer laptop or do I need to buy a particular board.

Thanks for any help

You can't convert it. The motherboards are custom-fit and type. The video cables don't match, etc., etc.

G5 is a powerPC processor, Intel means with Intel processor. So, G5 and Intel don't go together.
These units aren't inter-convertible, because of different cables, etc. An iMac G5 - even when running - is only worth about $125. Buying all the parts and swapping would probably cost more than that.

Maybe you should look for a used Intel iMac?

Another important thing to mention to your first question, You could not use a Non Apple (Acer) Board even if you could make it fit. You can not install OSX on anything other than Apple hardware without breaking Apples EULA and the DCMA copy write act.

I'm just taking apart my iMac G5 (iSight) so I can replace the LCD. I accidentally smashed it with a speaker (Yes, I cried). I was just wondering what size the Torque bit is. I've searched, and searched for a bit small enough, but they all seem to be too big. I can't seem to find the bit size information anywhere.

Anybody want to tell me? I'll be uber happy and stuff. And please don't go spew crap about excess junk that you think will make you sound smart (That's what I've always seen).

-Much happy,
Your friend,
With love,
Abracadabra,
See you later,
Love,
Kurt.

First of all...it's a "Torx Bit"...not a "Torque Bit".

As far as finding the correct size bit. Just buy yourself a precision screwdriver set...such as this:

Precision Screwdriver Set - 33 Piece

It will contain just about anything you need.

Not being one to debate the point with our learned staff, but Nick they are in fact Torx bits and not the torque power of an engine:-

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

I'm confused Harry...that's exactly what said in my post (1st sentence). They are called "Torx Bits"...not "Torque Bit".

Good the plan to create confusion is bearing fruit!
