When building a custom computer rig, most people put the SMPS power supply inside the computer case. [James] a.k.a [Aibohphobia] a.k.a [fearofpalindromes] turned it inside out, and built the STX160.0 – a full-fledged gaming computer stuffed inside a ATX power supply enclosure.
While Small Form Factor (SFF) computers are nothing new, his build packs a powerful punch in a small enclosure and is a great example of computer modding, hacker ingenuity and engineering.
The finished computer uses a Mini-ITX form factor motherboard with Intel i5 6500T quad-core 2.2GHz processor, EVGA GTX 1060 SC graphics card, 16GB DDR4 RAM, 250GB SSD, WiFi card and two USB ports — all powered from a 160 W AC-DC converter. Its external dimensions are the same as an ATX-EPS power supply at 150 L x 86 H x 230 D mm. The STX160.0 is mains utility powered and not from an external brick, which [James] feels would have been cheating.

Badly, of course, but the machine is a wee bit smaller. And we're talking about a RPi 1 era.
It's a different class, though — as you can see from a rather extreme radiator-to-computer size ratio, and that an extra screw-on fan is recommended addition, the thermal budget is drastically bigger than on other cheap SoCs, and it does make use of it.
The concept of putting an entire computer inside what usually holds only a minor component is funny, and the scale is different enough.
But then, imagine that back in the days some folks used to put an entire computer inside a keyboard...
