Surprisingly, Dell hasn't seen fit to include a low or zero insertion force socket in the 433/L.

Devices with hundreds of leads may be inserted in zero insertion force sockets, which are also used on test equipment or device programmers.

Socket 604 was designed by Intel as a zero insertion force socket intended for workstations and server platforms.

It also has leads that are designed for use with throughole pcbs or with vertical input zero insertion force sockets.

The chip then eases right out, thanks to a Zero Insertion Force socket, which uses a small lever to open and tighten the holes.

Pentium M processors in PGA package have 479 pins that plug into this zero insertion force socket.

Where devices would be frequently inserted and removed, such as in test equipment or EPROM programmers, a zero insertion force socket would be used.

It is compatible with official NES games (as it carried a 72-pin connector, though it did not had the zero insertion force socket the original NES has), and also with copied and bootleg games, as it does not have a 10NES lockout chip.
