Maybe someone can help: is it possible to build an SBC can boot Linux and has just a CPU, gig ethernet and gobs of RAM (at least 8gb)? Don't need display port,

  Are you asking if it's possible, or asking for advice on a practical way to get it done?

    If its at all possible, and if so, has someone built such an SBC? Alternatively, is there a practical way to attach external DDRAM to an existing 64-bit SBC, perhaps using the GPIO pins? I have zero electronics knowledge so forgive my questions if they are stupid.

      DDRAM requires too much speed to do something through the GPIO or USB... What you could do is use the Tinkerboard S, boot off of a microSD card and use the integrated eMMC storage as a big 16gb swap partition... or just partition the eMMC into an 8gb boot and 8gb swap to give you 10gb usable.

      It's definitely possible. Has someone built exactly that? I don't know; there are hundreds of variants of single-board computers, and I'm only familiar with a few. It's not something that you'd build by buying a couple of parts and soldering them to a breadboard. As for attaching memory, GPIO probably gives you a transfer rate on the order of a few MB/s. There are various things like SPI-connected SRAM chips, but those don't provide a lot of memory (think KB, not GB).
