Just received a Beelink X2 I ordered from eBay for $29.92 with free shipping. Downloaded Armbian and flashed the image to a microSD card, rebooted and ran the nand-sata-install script. Configuring the wireless was simple and now I have a Quad Core Arm system with 1GB RAM, 2 USB 2.0 ports, a microSD slot and a free 10/100 Ethernet port. I have a CP2102 USB-TTL Board in one of the USB slots for connecting to my various Kirkwood boxes and can use the other USB and/or microSD slot for flashing images for them. The 10/100 Ethernet port allows me to keep them isolated from my network until I have a current Debian image installed. I consider this < $30 system a bargain!
