Any ATmega32u4 based board should work.
My first build was sleeker. I used small push buttons and had a choclate bar design. Since the buttons were too small, my hands started to hurt after using it.So i decided to make it with larger button.I kinda like this psp style form factor so i changed the design to this.And i wanted to have larger pads and trace width. If you want you can use my desgin files as a refernce. You can find my designs from here : https://easyeda.com/B45i/Arduboy_clone-da02c53b733545e0a771ebc4e5b6e590
Original arduboy uses a piezo. Si i decided to keep it that way.
