One more vote with OP. That Atari is a nice looking machine.

Technically neither a console nor a PC (in the IBM-compatible sense), but the Commodore PET has a certain kind of 70s futurism about it.

Note the integrated tape deck for all your storage needs.

The keyboard pictured, while interesting looking, is a complete POS. Later PETs had a more usable keyboard with a better layout.

Edit: I don't think that red button at the bottom right is stock. It's almost certainly a hardware reset button, which on the Commodore machines is typically done by shorting a couple pins on a user expansion port.

The Atari Portfolio (the one John Connors uses in Terminator 2) or the ST Book.

I like the woodgrain look, but I don't think the Atari 2600 is a very good example of it. Lots of audio equipment from the time does it better. Especially when combined with brushed aluminum or stainless steel.

Purple GameCubes are retro now, so I'll go with that as my favorite.

Console: Sega Dreamcast

PC: Any IBM beige box from the 90s

Damn, wood. Or wood-looking material at least.

Original sony playstation. I don't know why, i just love it
