It might be too pricy, but if you go to about 25usd/month, you can get a dedicated server with an i7 from hetzner server auction. These cheap boxes don't have ecc ram etc - but should work well for things like this. https://www.hetzner.com/sb?country=us
On the page, one option advertised is for €23.53/month with an Intel Core i7-4770, 2 TB HDD, and 32 GB RAM. What’s the catch? How is it possible to rent such hardware for so cheap?
Edit: For a little more a month, you can get a Ryzen 3600, 64GB of RAM and much faster NVMe SSD: https://www.hetzner.com/dedicated-rootserver/ax41-nvme
