Awesome, your sir are a brave soul.

Is it possible to determine what Intel chipset is being used? Northbridge and Southbridge?

Good thing I removed the logic board, I found a screw loose in the system. Could have shorted it out.

It took 15 min. to dimantle and put back together for me to do the posting. I did not look at the chipsets. I will look at the high res photos to see but I think there are heatsinks on them.

Thanks anyways.

It looks like the plates with the heat pipes are covering them.

It looks like a pair of heat pipes are running off some kind of daughter board, could that be the MXM PCI Express connector?

Caslon, would you be interested in helping the MacEFIx86 project extract the Nvidia firmware? BTW which graphic options did you get, the 7300 GT or 7600 GT?

That is the MXM PCI-E card slot. The other set id over the processor. It is a 7300. I would be happy to help.

Wow, thanks Caslon. I bet my 20" looks similar, but I'm too chicken to find out...

The LCD has no markings other than a white barcode sticker.

wow :D

brave man, I'm thinking of buying a new imac, altho I'm not sure if it would be better to build a hackintosh. Wonder if it will be possible to use the 7600gt drivers from the 24" imac for a 7600gt in a hackintosh :) probably not tho :blink:

Just tried an ATI X700 PC MXM card in my iMac 24. It worked in XP dual boot mode But crashed as soon as mac tried to boot. Have not recieved my 7900 card yet, I'll let you know if it works. Most likely it needs firmware for mac to see it.

Was reading about people using standard pc graphics cards on the mac pro.

'PC' video card ROMs are only 64K, whereas 'Mac' cards are 128k. The reason for this is so that Apple can have full-color and full-resolution boot sequences and boot menu (what you see when you hold down option).

Therefore, whatever ends up happening, all PC video cards on a mac (if they run at all) will have a black screen until the OS loads the driver. This hand-off between the video card's ROM driver and the OS driver occurs just before the login screen. (2)

Not sure if it's the same for the PC MXM cards or not tho.

It is easy. Just be careful removing the metal tape arounrd the lcd panel, remove the screws that hold it down and lift the lcd panel and there it is.

Does anyone know what kind of hard disk is in these things? I'm thinking of getting one, but I'd rather not replace the hard disk (added expense, though I could install it without problems). However, if it is a Western Digital model, I *have* to. {censored}tiest brand of hard disk ever. Three of my friends who have iMacs had their WD drive fail on them.

BTW...did you guys see that the old 32-bit 20" iMac is selling for around $1100? Great deal.

What would be better - a 2 GHz MacBook Pro ($2000), or a 2 GHz 20" iMac CD and a PowerBook G4 (around $2000 together)? I'm thinking the latter.

Mine came with a Seagate 250. I replaced it with a Maxtor 500. The few people I have talked with thet got 500s installed from Apple, said they were Maxtor 500s. SATA II 16 meg cache drives with 7200 rpm only due to heat issues.

Also you can upgrade the old Intel core duo with the cor 2 duo processor. So if you get a cheap deal it's worth it. The new 20s are the machine with a newer processor. Sam socket and everything else.
