Raspberry Pi enthusiasts may be interested to know that the pi-top  DIY Edition Raspberry Pi case complete with integrated battery, cooling fan, mini OLED screen, speaker, programmable buttons and power management system is now available to preorder priced at $99or £95. Worldwide shipping is expected to take place sometime during this month and the internal battery is capable of providing up to 5 hours of use from a single charge.
Or you can use your own 15V USB-C PD power supply, the pi-top team recommend using a 30W minimum for maximum accessory compatibility and you can purchase a power supply for the pi-top  DIY Edition Raspberry Pi case directly from their website.
One downside is that you need to use the companies custom operating system “to get the most from your pi-top”. “It’s best to run pi-topOS. Some of the advanced features of pi-top are not managed by Raspberry Pi OS (formerly Raspbian) or other operating systems” say the development team.
