Not sure how available it is though since it’s not canon.
The dvds are out of print but iso files of the american discs can be found on the spleen (and maybe elsewhere).
I’ve said it many times but I stick to my position: Tartakovsky’s Clone Wars is the best thing that happened to Star Wars since the OT. It gives in around 2 hours most of what I wanted to see in the PT (Anakin/Obi-Wan friendship, Anakin being the best starfighter pilot ever, intelligent references to the OT - Yavin IV duel ! -, badass vilains - Ventress, Grievous -, more depth - the heroes journey that foreshadows Anakin’s fall -, more mythology - kyber crystals, lightsaber construction -, and breathtaking action scenes - gosh, the entire battle for Coruscant is great!).
Without the microseries, the PT is lacking its heart. I’ve always thought that Lucas probably was upset the PT was a Trilogy since its narrative works better as a 4 part story, otherwise the infamous Clone Wars only happen at the end of Episode II and end around the middle part of Episode III. He probably was also upset this cartoon was way better than expected, so he “erased” it with a CGI version which is nowhere near as good.
