But if they still charge you $20 for the hacked/pirated version and full whack for the sealed copy ... there could still be a problem.
Maybe. That isn't the situation though. They are selling you a computer running a modified version of OSX pre-installed and a sealed copy of OSX. They aren't charging you extra, they're only charging you for the hardware.
But then you are selling two copies, one of which is a derivative work you had no legal right to sell, or maybe even make.
Wrong. They are selling the original copy and giving away derivative work for free. Would you be OK with it if instead of a derivative work, they gave you detailed and simple instructions on how to create the derivative work yourself if you chose to do so?
So what sort of work do you need doing that an iMac cannot achieve? The current ones are faster than the old PowerMac G5s, and they were used in professional recording studios running Pro Tools etc...
Can I upgrade the video card in an iMac? If I already have a monitor, can I order an iMac without a monitor? Can I put in two or three more hard drives for RAID? How many PCI slots does an iMac come with?
Get the picture yet?
What? Just because they also sell you the original, it's then ok to rip off someone's work and sell it for a profit?

Who is ripping anything off or selling anything for a profit? They are selling Leopard "for a profit" the way Amazon or any other retailer is selling it for a profit. They're making a profit on computer hardware that they order and build into a computer that runs a slightly modified version of OSX.
You, the customer own the OS and the computer when you receive your order.
