You don't need to spend $1k on a NAS. Go on eBay and buy an old motherboard with 6 SATA ports and an m.2 slot for the OS. I see one with a CPU for $88 incl. shipping right now. You might be able to do better. Throw it in any case. If you don't have one, buy any ATX tower on eBay for $30. You might even be able to combine the previous two steps. If you don't have enough bays, just leave the tower on its side with the disks floating somewhere. I did that for years when I was a teenager and it's fine. Then you just need a PSU and disks. Or if you're into nerd stuff like this you might have an old computer that you can reuse and you just need disks. You also don't need to leave it on 24/7. Around me the bottom tier download for Comcast is 75 Mb/s, which is 5-10x the bit rate of streaming, so after an initial period to get you started and build up a buffer, you should be able to build your collection faster than you can watch it on average while only keeping it on while you watch.
