I want to get into homelab and I have a 60-100€ budget

I am planning to run a headless os for Jellyfin DVD and music streams, as well as hosting roms with RomM and having a tailscale instance or a reverse proxy. I have found a 50€ thinkcentre tiny with a 4th gen i3, 4g of ram and a 500gb hdd, with 30€ shipping. Is it good enough or are there better options within my budget
