Guessing that this is a somewhat older case, the power supply being at the top like that it’s pretty close to the motherboard and CPU power sockets and the drive bays, and GPUs could often run from motherboard power. You might have those huge grey IDE ribbon cables for floppy drives, you usually had the ketchup and mustard power wires, who cares what the thing looked like inside?
