This picture has been going around on Facebook a bunch. I can identify all but two of them (left to right):
Top Row: Famicom + Famicom Disk System; ???; Atari 7800; PC-Engine + PC-Engine Super CD-ROM²; NES; NES Top Loader
Second Row: Super Famicom; Sega Genesis Model 1; Neo Geo AES; ???; TurboGrafx-16; SNES
Third Row: Sega Genesis Model 2; Japanese Sega Saturn; Panasonic 3DO FZ-10; PC-Engine Duo RX; Sony PlayStation; Atari Jaguar
Bottom Row: Sega Dreamcast (not sure if the green color is a limited edition or a custom mod); Neo Geo CD; Microsoft Xbox (again, not sure if the color is limited edition or custom); Sony PlayStation 2; Nintendo 64; Nintendo GameCube
So it's just the second one in the first row and the fourth one in the second row that I don't recognize. If I had to guess I'd say they look like 90s machines of some kind just based on the design aesthetics, but they don't look like any that I know of.
