Google is your friend. Search for "802.11a PCI card".
<http://www.proxim.com/products/cp/pci.html>

There are plenty of PCMCIA/CardBus dual band cards available. All you
need is a CardBus to PCI adapter.

One of my customers uses this because their worthless software vendor
keyed the copy protection to the wireless card MAC address. So, to
use it in multiple locations, he moves the card.

There are also adapters between MiniPCI (laptop) cards and PCI. Many
PCI wireless cards are these adapters, with the MiniPCI card
"integrated" onto the board.

One of my former customers had a problem with employees stealing the
easily removable antennas from the wireless desktops. Amazingly, some
of them still work with no antenna. If you go with PCMCIA to PCI
adapter route, the card can easily be removed and stolen. If USB is
unacceptable due to theft issues, I don't think the adapter solution
will work for you.

Reminder: MIMO Pre-802.11n and such is all about speed (at least the
spacial diversity style is). It's not going to give you more range.
If you're shooting through walls or more than perhaps 20ft, might as
well buy an 802.11a PCI card.
