I’m no programmer but I do know basic networking and computers. I have about 5TB worth of storage (more is to come) to spare, a 1Gbps connection and a public (although dynamic) IP address. Is there any need for hardware contributions, as in, for instance, hosting, doing backups, anything?
You could also look into hosting a distributed Garage cluster for S3 compatible media storage with a few other people. Most fediverse software including Lemmy is compatible with that for image storage etc.
