When my local inversity was throwing out their old SPARC stuff I filled my car to the point where it looked like a cartoon caricature of an overstuffed car.

I had two full racks of SPARC, DEC Alpha, SGI, and other trash, in my one bedroom apartment.

Now my experiment hardware is raspberry pi and RISC-V stuff (visionfive 2 & orangepi RV2). Much more manageable with space, noise, and power bill.

I did the same thing in college, in 2003 or so! I had a whole polyglot UNIX lab in my college dorm room; pizzaboxes, SGI Indigo 2's and an Indy, a NEXTStation, random PPC Apples, an Atari Mega ST 2... I remember my RA checked it out and he just looked at it and nodded. No clue what anything was, just "yeah, technically this isn't breaking any rules..."
