I wanted a custom case for the PX-5s, but on www.shopcasio.com's website, the PX-5s is not listed as a model that fits in the case. I ordered it anyway from Guitar Center and want everyone to know that the keyboard fits like a glove. The link to the case is http://www.shopcasio.com/product/2522. It does not offer significant protection, but if you're like me and baby your gear, you'll love this case.
