My family has an HP Pavilion slimline PC which has a single PCI card
slot. It came with a crappy softmodem PCI card installed, which I
decided to replace with a Wireless-G PCI card. The case is very slim,
about 100 mm wide, so that the DVD drive has to be mounted vertically.
The motherboard is a microATX motherboard with dimensions of 6.7"x6.7"
(it looks like this: http://h10025.www1.hp.com/ewfrf/wc/d...ng=en&y=0#N813
When I removed the modem card, I found to my surprise that the
backplate of the modem was actually significantly shorter than a
standard PCI card. Perhaps a little ASCII art will illustrate what I

Basically, this PCI card is totally identical to a "normal" PCI card
that would go in any mini-ATX desktop case, EXCEPT that the backplate
is only 80 mm long from the tab to the point where it screws into the
chassis, rather than the 120 mm or so for a "normal" PCI card. This is
presumably to allow a slim case (the whole case is only about 100 mm
Since the card itself was only about 60 mm in depth, I was able to make
the "normal" PCI card card fit in this case, after some rather heroic
modifications. I had to remove the backplate from the card, cut it
short with a hacksaw, bend it, and drill a hole for the mounting screw.
I'm wondering if anyone knows what this shallow-depth PCI card is
called for future reference.
I've had trouble finding publicly available documentation on the
official size of PCI cards. Wikipedia has only the barest information: http://en.wikipedia.org/wiki/Periphe..._physical_size
I gather that a "standard" PCI card that fits a modern motherboard is
actually a "half-length" PCI card.
Thanks for any advice,
