Have a look on FB market place for an old PC.
I DIYed mine out of an old one i had knocking about, just chucked a 1TB ssd druve in there, reformated it to factory defutls then over wrote the OS using the image downloaded from the nostr:npub126ntw5mnermmj0znhjhgdk8lh2af72sm8qfzq48umdlnhaj9kuns3le9ll info page 👍🏻
You can do this, im 49 with the tech skills of a 70 yr old and i got it done 😁😁
