This is a bartop arcade that I built for a buddy of mine a couple years ago (owned a crappier phone then). I've built several others since then but haven't made any videos showing them. Plan on doing some more later on.
These are so much easier to do with modern itx boards with M.2. Or even cheaper yet, use a Raspberry Pi.
This project used a slow 5400 rpm laptop drive. So much nicer stuff to use in 2019', like Noctua's NH-L9a or NH-L9i, low profile coolers, the Ryzen 2200g, onboard M.2, and yes, even motherboard 12v/5v addressable RGB headers.
