Expandability
The PXi allows addition of an expansion card (PCI) like wireless (RF) network adapter, modem card,
multi-port I/O card, or SCSI card. You will not lose any funtionalities when using this feature. The
dimensions remain the same (except the thickness/depth increased by 1.25"), and can still be wall-
mounted. In most cases, users will not notice the difference. Below is some comparisons.
