Banana Pi is working on the upcoming Banana Pi BPI-M7 SBC powered by Rockchip RK3588 SoC whose low profile design reminds me of boards from Khadas such as
The Banana Pi BPI-M7 single board computer is equipped with up to 32GB RAM and 128GB eMMC flash, and features an M.2 2280 socket for one NVMe SSD, three display interfaces (HDMI, USB-C, MIPI DSI), two camera connectors, dual 2.5GbE, WiFi 6 and Bluetooth 5.2, a few USB ports, and a 40-pin GPIO header for expansion.
That "SBC" has a strange price point because it is Intel and costs 250$. For 100€ you can find an HP Mini with an i5 8th gen + 16GB of ram + 256GB NVME that obviously has a case, a LOT of I/O, PCIe (m2) comes with a power adapter and outperforms a RPi5 in all possible ways.
I'm looking for something to run Open Media Vault. Fast Ethernet and multiple drive options. I also like to tinker, the prebuilt mini PCs haven't interested me much
