It's weird that there is no tier that offers everything from the Standard tier (case, fan, display, power supply etc.) minus CM4. I'd rather trade Wi-Fi capability for more eMMC storage, considering this thing will likely sit right next to my router anyway.
This is an interesting suggestion. We actually do plan on selling the case separately, so you could just buy the "Hacker bundle" and the case and you'd be good to go. You can see the customization we plan to offer over at https://pibox.io - but for the kickstarter we simplified things a bit!
