Sawed off riser card (Score 1)

Worked at a computer repair shop in the Packard Bell days. A person brought in a 486 Packard Bell with a bad motherboard. I had a PB motherboard from a different system that would fit but the riser card, specific to it, was too tall for the case. I told my boss it wouldn't work because the riser card was too tall. The Riser card had 3 ISA slots instead of 2 like the old one. My boss said just cut the top one off. He put the riser in a vice and cut off the top ISA slot with a Skill saw. I put the newly shortened rise card in the case. Turned on the computer. And the tested out the 2 remaining ISA using an internal modem. Some how that motherboard and cut riser card worked.
