Old Computer Parts Going In The Trash

[fast eddie]

Ever looked inside a computer and the backplane of a computer built in 2001 compared to a computer built in 2012?

Where is the connection for a PS2 keyboard and PS2 mouse?
Where are the IDE connections primary and secondary off the motherboard for a dual layer IDE connection optical drive?
Where is the serial connection on the backplane?
Most new high end motherboards don't have but one high end card slot and is used for the graphics card.
Super light case almost looks like it is made of plastic.
Is everything going to a USB connection?
