Ehh, please point me to some of those... I don't think that I've ever gone THAT LOW on the CPU side. Sure that you're not confusing my E-350 builds, and my later Ryzen 3 1200 builds? E1-1200 is pretty darn low-end.
I did fiddle with some C-60 nano-PC units, for personal usage / HTPC / internet radio. They kept eating my SATA SSDs installed in the chassis, due to high temps, due to passive cooling of a 10W APU.
Edit: Are we talking about that Gateway 21.5" AIO I bought on clearance at Staples for like $100 or something, used for six months, tried to pawn off on someone, got it back, installed a 500GB Samsung EVO SATA SSD in it, and gave it away to one of my neighbors? (Whom I think is still using it.) Since that was a pre-built OEM rig, I don't really consider it to be one of my "builds".
Edit: And for the record, I don't build anything lower than a quad-core these days. Well, except for the little stock of prior parts I have on hand, like an A4-6300 FM2 APU that I've got NIB to use on an FM2+ board I've also got NIB, and a 4GB stick of DDR3 to throw in. Trash machine to give away.
