Yeah how about a desktop model of the below monster
The first UNIVAC I mainframe computer was delivered to the Census Bureau. Unlike the ENIAC, the UNIVAC processed each digit serially. But its much higher design speed permitted it to add two ten-digit numbers at a rate of almost 100,000 additions per second. Internally. It was the first mass-produced computer. The central complex of the UNIVAC was about the size of a one-car garage: 14 feet by 8 feet by 8.5 feet high. It was a walk-in computer. The vacuum tubes generated an enormous amount of heat, so a high capacity chilled water and blower air conditioning system was required to cool the unit. The complete system had 5200 vacuum tubes, weighed 29,000 pounds, and consumed 125 kilowatts of electrical power.
