Look into buying a used Dell c410x GPU chassis (they are $200 on my local CraigsList) and a Dell R720. Then add some cheap GPUs.
For a few thousand dollars you might get some processing power.
But you will never be able to pay your electric bill.

But I just looked again, and A100's are not around at reasonable prices anymore. I cannot even find the old mining equivalents (they used to be everywhere, and CHEAP). Perhaps many people are building similar systems now. After the Ether merge it was a great time to build.
