I'm quite proud of my Rat-Miga.
It's built around a 1993 A1200, with Mediator, Voodoo, Apollo 1240, Twister, 4-way IDE interface and SB128 all packaged into a second hand Power Tower and treated with benign neglect.
The keyboard is a fetching beige AT item, carefully decorated with coffee stains, breadcrumbs and an unidentifiable sticky subtance bonding the right shift key down. The mouse is of 1991 vintage, with a cable cobbled together from an even older mouse and is suitably battlescarred.
