Ah, that picture brings back memories - I used to have a successor of that machine in the mid nineties (PS/1000), it looked almost the same, except the handle was rounded and the power button was blue (a big blue button). And the CPU was IBM's very own "Blue Lightning" 486SX clone (75 MHz, but no FPU). It ran Doom great, but had to pass on Quake, which required an FPU for its polygon-based 3D graphics.
