I use an distro called ‘Bunsen Labs’, which was created as a successor to CrunchBang Linux when maintenance of that distro ceased. It uses OpenBox as the WM, and works well for an old laptop and for random VMs I spin up to test things (my test Lemmy instance runs on it).
crunchbang is awesome, never did the bunsen labs, but i do have a live crunchbang plus plus usb for recovery and lightweight live distro. i think its debian 12 with openbox.
