Basically you need to find an old workstation or micro tower that is implicitly not a small form factor PC. These typically come with power supplies that are ready to accept larger GPUs like you seem to want.
Still, cards like the GTX970 require PCIe power connectors. You need to make sure the PC you get has the appropriate ones for the GPU you intend to install.
Now, sadly there is an entire industry dedicated to snatching these up, adding a GPU, and then re-selling them as 'gaming' PCs. You could just pay the premium and pick up one of those. Or hit up the used market for discrete components (recommended if you are a really tight budget)
Here is a pretty low end one on Amazon:
Or you could see if you can track down some CPU/Motherboard combos. Memory and storage have never been cheaper, so you can always stick to new for that or low ball people on ebay.
Not what I would necessarily pick, but people do have them out there:

Seeing 1050Ti out there for about £35.
But even so, with just a little more money into it, all new entry level parts. Just have to track yourself down a GPU.
