YOW is a PC Engines APU2C4 that I purchased in October 2017 from mini-box.com. It is smaller than the NEXCOM at about 6 5/8" x 6 1/4" x 1 1/4".
It is another fanless computer, it uses the AMD GX-412TC CPU, but this computer has no moving parts. It is actually a bit eerie how quiet it is.
I am using a 64G mSATA Recadata SSD. I am currently using about 6.5G, so 64G is more than enough. And I am hoping that the smaller SSD will run cooler and therefore last longer.
I also purchased the optional wireless that was to replace my WRT54G. But the wireless just didn't have a strong enough signal from the basement, so I went back to a wireless router on the first floor.
This computer is overkill for a router... which is just the way I like it ;)
