Tough question to answer fully due to a lot of different variables.
First, GeForce cards were never officially tested or supported on S30. I'm guessing you know that, but just have to lead off with that :)
The power supply is going to be a major limiting factor when trying to bring your 13(ish) year old system up to more recent GPUs. The simple fact of the matter here is the 610W PSU that was used in S30 was never appropriately sized for today's larger and more power hungry GPUs. And making matters worse, the specs for GPUs in recent generations have a significantly higher input EDP current rating than those GPUs that existed when S30 was current. As we've not tested any of the GPUs in question on that platform, I can't give you a definitive answer on the power question. But I can relay that the top GPU we supported on that platform was the K5000, with a TDP of ~122W.
Also complicating matters on the PSU front was the fact that early S30 models went out with a single 6-pin PCIe power connector available. Later, that PSU was updated to add in a second 6-pin PCIe power connector. But that was mainly done to make it easier to enable dual GPU configs...the PSU is still rated at 610W and adding that connector didn't really add higher end power capabilities to that supply or anything.
As far as form factor, S30 utilizes a large plastic swing arm assembly to retain cards within the system. This arm generally interferes with the power connectors on most GeForce GPUs as far as I can recall. You could potentially remove the swing arm to allow for these GPUs, but just keep in mind that is an integral part of the physical design for that system, and removing it could result in increase risk of damage to the board when large/heavy GPUs are used.
Last thing to keep in mind is the fact that your S30 (running A0 BIOS) is a first gen S30 that was limited to Legacy BIOS support only. This means whatever GPU you attempt to use is going to need a Legacy OPROM available in order for the the system to boot properly. Many devices utilize a hybrid OPROM design that supports Legacy and UEFI, but just a warning that UEFI only devices would likely have issues booting in this system.
Hopefully somebody else from the forums can chime in with their experiences running non-supported GPUs on that platform. Most of what I've listed above are more things to watch out for as opposed to guidance on using specific GPUs from your list.
