I love this tiny Raspberry Pi Macintosh SE/30, and you can make your own
It's even usable.

If you want to relive the retro days of the 80s and 90s computing scene, but you don't feel like buying authentic hardware that looks the part, why not 3D print one instead? Okay, maybe 3D printing an entire fully-sized PC is a bad idea, but you can compromise and instead create a tiny replica of your favorite PCs. That way, you can get a miniature blast from the past that doesn't take much to make, sits on your desk, and makes for an excellent talking point.
