Why are graphics cards upside down? D:

Probably because heat rises so they want GPU's to be sucking in the cool air opposed to the warm air, if it were the other way around the GPU would be sucking in hot air from around the CPU heat sink and probably affecting its airflow.
 
There was some reason for this that I can't quite remember ...

Many high end cases actually invert the whole motherboard ... 900D, PowerMac G5/Mac Pro, some larger Silverstone and Lian Li cases ...
 
Maybe because it's the position of the PCI-E slot? It's kinda on the upper side of the expansion slot. It's probably better for the vard anyway, seeing as cooler air is generally at the bottom of the case (heat naturally rises after all).
 
Actual answer:

"We used to have ISA slots. The cards were right-side-up. When PCI was being developed, designers wanted to give builders a choice of using up to six PCI cards or six ISA cards from a single 8-slot AT case. To geth PCI and ISA to serve the same slot hole in the case, the PCI slots were placed between the ISA slots. Then, to get them to align with the hole, they were made upside-down.

With this design you could have an ISA card one slot above the PCI card and still have enough room between them to prevent shorts, and motherboard designers didn't have to take away one slot to add the other.

AGP followed PCI design, the PCIe followed AGP design."

They could at least do us a favour and put the graphic designs and pleasing aesthetics on the tops of the cards so we can appreciate it :)!
