I'm looking forward to your review too. I just got a case in the mail from AliExpress and it's a nice fit, although a little long.
Here's the link to the cover. It came in 2 weeks and fits well enough. I posted picture of the reader in the case in my review at AliExpress.

Also, have been using it since may 27 and I love this reader. I don't do a lot of font changing, but it does okay with most of the apps I've used. Yes music plays through bluetooth easily as long as you install an app. I use phonograph. Overdrive is fine too.
