My 2.5 year old loves watching classic Pokemon. I'll be honest, so do I. But have you tried doing that? It's fucking insane.
The first half of S1 is on Netflix
The second half is on Amazon but you need an extra subscription to watch it.
The theird season (johto) is also Amazon.
The 4th is no where but Archive.org of all places... Which is called Johto Champions, so it really feels like the end of the season but it's another 52 episodes!
You would think pokemon.com would have all this (they have a lot, and it's all free) but they don't!
Seeing S4 (is that even right?) On Archive.org is really pushing me to want to build a Plex server. Having all this content in one place would be very nice.
I do IT work by day, and I have some older 2TB platter drives from a retired camera server laying around. What's the easiest way to get my foot in the door? Do I save up some $$ for a Synology box?
I set up my Plex server in 2021 for under $300 USD, using an old PC case I already had. I built my system around the AMD Ryzen 3200G. No graphics card, 8GB RAM, and Ubuntu Server. I've never had more than maybe 2 - 3 users streaming my Plex at a time, but its been chugging along with no issues for about 2 years now. For what I use it for, performance has been great, and obviously it didn't break the bank. I'm probably going to add a dedicated GPU at some point for hardware transcoding, but other than that, the wife and I are happy with all our content in one place. Go ahead and build it yourself. You don't have to go big $$ up front. Just build what you need and expand later if you want to.
