This type of content is always satisfying to listen to lol. In terms of your storage maybe create several google accounts and upload them to google drive you can save space that way since a free account offers 15gb of storage. I'm 100% down to see a setup video too it would seem cool!! Also it's so nice seeing supportive people around you regarding your YT channel.
By the way, perhaps you could upload videos to youtube here so that they do not take up so much storage locally. Just make them unlisted. Or you could get an SD Card/DVD and put the videos on those as a sort of backup/space saving method? I do that with music I buy on Bandcamp because the music is DRM-free (no limits on burning the music to CDs).
