Shuttle AN51R nForce3 250
 

There isn't anything too exceptional about the layout of the AN51R. Even though there are plenty of capacitors near the CPU socket, they are low enough where almost all heatsinks would clear it. The ATX connector, IDE1 and 2, and floppy connector are all conveniently bundled near the top back of the board which makes wire management easier, but once again, the 4 pin 12V connector is located clear across the board right below the CPU socket.
