You’re getting a lot of advice in this thread and it’s all pretty good, but not all of it seems to answer the problems you have in your order of priority or under your constraints. I’ll try to give an explanation of why I think my advice will do so then give it.

Getting off usb will speed up file access and increase the number of operations you can do from the laptop on your lan. Some stuff will still need to be copied over locally, normal people like us just can’t afford the kind of infrastructure that lets you do everything over the lan. For those things, rsync is perfectly good, and they’re most likely going to be enough of an edge case that it won’t be very often.

When you’re ready, and from your responses in this thread I’d say you are, a vpn doesn’t expose you to much security risk if any. There are caveats to that, but if you’re doing something like openvpn or wireguard it’s all encrypted and key based and basically ain’t nobody getting into it unless they were to get a key off an old computer you use and didn’t wipe before throwing out or something. That would solve your remote access bonus problem. No pressure and in your own time, of course.

You are me twenty years ago.

Don’t ever change.

So you want to kick the bad habit but don’t have enough physical space in your desktops case or enough sata ports! You have a bigger tower case but don’t know if it’ll really hold the drives you want.

The best bet is to transplant the motherboard and power supply from your sff desktop into the big case. If the big case has at least three 5 1/4 bays you can use a bracket to go from 3 big bays to 4 or 5 smaller 3.5” hdd bays. I’d recommend 4 instead of 5, more on that later.

If the big tower case has the little dangly 2x 3.5 bay cage hanging down from its cd cage, you can use four strips of sheet metal and a carpenters square (or the square corner of some copy paper) to make a column of hdd mounting space all the way to the floor of the chassis. Just remember to use vibration damping grommets.

Make sure when you’re filling your tower up with drives to put some fans blowing on em. Drives need to be kept cool for maximum life. Those 3 cd bay to 4 hdd bay adapter brackets are nice for that because they usually have a fan mount or one included.

Now you need sata (or maybe ide) ports to plug all these in. Someone else already said to use those cheap little sata expanders and those are great. I used an old cheap pc mounted in a salvaged case just like you might with four of em back in the day.

You’ll actually want to use the towers power supply if it has one and it works and matches the sff desktops connectors because it probably has more power capacity than the sff desktops supply. You may need some molex or sata splitters to get power to all your drives.

Consider mergerfs and snapraid once you have this wheezing Frankensteins monster operational.

Mergerfs displays all the drives as one big file system to the system and to users. So if drive one had /pics/dog.jpg and drive two had /pics/cat.jpg then the mergerfs of the two of them would have both pictures in the /pics directory when you open it.

Snapraid is like if raid5 (really zpools because you can have many parity devices) but it only runs once a day or whatever and is basically a snapshot.

Anyway sorry for the tangent. Post some pics of the tower case or its model number or whatever and I can give better advice about filling it with drives.
