eMac Upgrade questions

[DeltaMac]

No, you can't boot from USB with any PowerPC Mac. You'll need an external Firewire drive for that.
If, in fact, you have a 2005 eMac, you won't be able to install 10.2, because that model is too new to boot from 10.2
Even 10.3 will be too old for that one, it came originally with 10.4

This is when you will run into difficulty with your plan for the old iMac. You won't be able to install 10.2 on the hard drive for the old iMac, because the eMac can't boot to 10.2 to do that install.
Only the oldest eMacs (700 or 800 Mhz) will boot to an old enough system to install 10.2

i will buy a USB to FireWire 400 adaptor as its cheaper than putting more money into FireWire enclosures. This will work right? also about the iMac Tray Load i have a Laptop DVD Drive that is IDE and fits the adaptor board in the iMac can i use this drive to boot and install OS X directly on the system?

Then, it's not a 2005 model...
You said it's a 1GHz, which also means it's not a 2005. So (with bluetooth), it has to be a "USB 2.0" eMac, which is OK.
10.3.9 will limit you to older versions of browsers, and other software as well.
You CAN upgrade to 10.5.8, if you would want to do that. That's something that I would recommend, as 10.5 will give you lots of other options.... But, that would also mean that you would have to find the 10.5 installer somewhere - not cheap...

you happen the know how well if at all Ubuntu 10.04 PPC wil run on a eMac and use the AirPort AND bluetooth?

i already downloaded a Leopard Upgrade DMG can i upgrade to Leopard from Panther or do i need to first upgrade to Tiger? i have experience with Leopard via the OSx86 project its a nice system however there is two reasons i dont get a intel Mac 1 they are TOO expecive on eBay and 2 i HATE Snow Leopard the interface of Snow Leopard is beyond my preferences or know how. Leopard is pretty much like Panther except for a "Windows Vista" style interface. so i can use Leopard just fine.

Yes, I have an eMac here that I have Ubuntu installed, in addition to OS X 10.5.8
I have Ubuntu 11.04, which works fine. There is then an upgrade to 11.10, or even to the next 12.04 Unbuntu. I cannot get either to boot on the eMac.
I think that the best Ubuntu for your eMac is version 10.10
There are extra drivers for the Airport card, which works fine in Ubuntu.
Ubuntu installs bluetooth drivers, but I don't have bluetooth devices, and don't know if bluetooth works in Ubuntu.

Yes, you can upgrade directly from 10.3 to 10.5
You absolutely should NOT use the default Upgrade option from the 10.5 installer. You must choose the option to Archive & Install OS X. You'll see that simply by clicking on the Options button.
How much RAM memory in your eMac? 10.5 needs at least 512MB, and 1GB is better. 2GB is best, if you have an eMac that uses PC2700 RAM.

I think we can choose to disagree on Snow Leopard. I don't see much difference between Leopard, and Snow Leopard - except for much better performance. All it needs is lots of RAM.
It's not possible to use Snow Leopard on your eMac, so that's a moot point...
If you mean the current Lion (10.7), then I can definitely see your point of view. Lion is substantially different, and many Mac users find it difficult to get used to, for a variety of reasons. (but, using it for a while - I really like it a lot! I could go into the reasons, if you have any interest)

And, the 10.5 installer will install on either your PowerPC eMac, or any intel Mac that's more than 2 years old. The core2duo processors are so much faster than the G4 or G5, there's no contest. SO - you can have a much faster Mac, and still stay with 10.5 if you want to do that.

Intel Macs cost too much even on eBay id rather make a Hackintosh its easier and upon testing on my computers free as they all work flawlessy (except with monitors higher than 1024x768 resolution) my eMac takes DDR RAM it will come with 512MB RAM which ill upgrade to 2GB at a later date as DDR RAM is REALLY expencive compared to DDR2 and PC100 RAM also has a 40GB HDD which ill upgrade later using my 500GB SATA HDD with a SATA to IDE converter board and also my SATA DVD Burner also using a SATA to IDE converter board
