I have an older Gateway 700S computer that I would like to upgrade the PSU and CASE. What Im not sure of is if I buy a modern PSU, will it have a connector for a Socket 478 CPU Motherboard, and will a aftermarket Computer Case have Motherboard mounting holes that will line up with the Gateway Motherboard, it says its ATX. I could use some help, any would be appreciated!

You will have a tough time fitting that motherboard in an ATX case. It looks to be a BTX case by the picture, so no go on an ATX case. Now that I look at it again, it's not even a BTX spec case.

Any PSU with a 20 pin/20+4pin connector and a 4 pin aux connector will work fine. Basically any new ATX PSU will work, but
a new PSU might not fit your current case, and you current motherboard won't fit an ATX case, Catch22. Upgrade time. That motherboard won't fit in anything but that specific case.
