Just wanted to post my experience and usage notes thus far using UDOO X86 Ultra with the 32gb EMMC upgrade (just stating what exact hardware board I backed) with various operating systems. Notes about my setup: Using a MEAN WELL GS90A12-P1M 12V power supply ( Little bit of overkill, but these are really, really, really good power supplies). https://www.amazon.com/gp/product/B004P9UP6Q I had a Lenovo external USB CD-ROM to load operating systems from CD and DVD 8gb thumb drive 8gb micro SD card 32gb SATA SSD 128gb Apple SSD with SATA adapter ICY DOCK external SATA USB and ESATA enclosure I've installed the following OSs onto the system: Windows 7- after patching a bootable USB thumb drive with the required drivers. Booting from CD directly cannot install due to missing drivers and cannot get past the first install screen. Once loaded, still required more drivers for all hardware. Basically, Windows7 requires a fair amount of work to install and load all drivers on this newer modern hardware. Also, requires a specific setting in the UEFI to allow mouse and keyboard support. I could not install to EMMC so this was to SATA drive. Probably works with M.2 SSD but did not have mine yet for testing. Windows10 Pro- installed directly from DVD, works darn near out of the box. Only needed a few updates for everything to be functional. Probably the best matched thus far. Also, currently installed into the EMMC 32GB drive. Not exactly a ton of free space but roughly 10gb free. Again, probably a good choice for those who want/need Windows for their application. Android- Worked extremely well, installed to EMMC. This is another good and easy to use system. I did not exhaustively test everything under this, but again, install was pretty easy. Ubuntu- Also was very easy to install, put it onto the EMMC. Things not yet tested- Intel Curie, IR sensor for remote, micro SD card booting and installing/running OS, wireless card (was using wired network). Overall, I really like this little board. For everyone worried about thermals- stop worrying. Been running for about 2 days without a fan, not once in all testing has the CPU ever gotten too hot to touch. Barely even warm 99% of the time. Nothing on the board even remotely gets warm.
