Hey, I ran across an interesting product a few weeks ago. It is a $100 mini PC with a licensed copy of Windows 10 (64-bit). It has and Intel Atom X5-Z8500 (1.44 GHz), 2 GB LPDDR3 RAM and 32 GB eMMC SSD internal memory. It even has a fingerprint reader! This is plenty capable to run most emulators (even N64, dreamcast, psp, etc.) and even some Steam games like Brawlhalla (awesome smash bros clone). I've had no problems running Hyperspin with all the media installed, and RetroArch is running great as well. I waited until mine got here to to try it out before I reported on it, and I must say - I'm very VERY impressed. My next bartop build will definitely include this mini PC, and I may even switch out the PC in my upright cab. Here is a link:

It could at least provide a decent starting point for someone to then either add or remove games and that's all they'd have to set up, theoretically.
Buy cheap pc-->Download package-->Add roms
Let me know what you guys think of the PC!
