The short answer is No

Here's an old Tom's forum post discussing this - bemoaning the lack of more than 5 PCI slots. http://www.tomshardware.com/forum/140707-32-adding-slot...

The only solution discussed is a device for rack-mounted servers called a riser card. Couldn't find a lot about those but went here
http://www.rackmountnet.com/advanced_search_result.php?...

One thing clear is that the cost of almost anything rack-mounted is far in excess of replacing your current motherboard with one that integrates LAN into the motherboard and has more slots. Besides the extra PCI slots you might have some benefit long-term of being able to move into the 1 Gbit LAN standard.

I'd say that any board with only 2 PCI slots isn't a real Server motherboard anyway - seems quite limited. And any newer board with a newer CPU and such would be faster. But of course, then you get to solve all the problems that come with a server upgrade!

Would be good to know the exact brand/model of your motherboard and what the other device is if you have further questions.

OK, I've found some more info and the prices are actually quite reasonable.

What I believe you are looking for is called a PCI 32-bit Active Riser 2-Up or 3-Up.

Remember, what I know about this subject is what I've just learned since you asked your question! Let me break down the specs of what you need:

32-bit PCI - You want normal PCI, not PCI-E or PCI-X or PCI-8, etc.. must be just plain PCI. And you don't want 64-bit PCI - a larger type found on some servers (I assume this isn't what you have now)

Active Riser - There are many Risers out there which are designed to change the way cards fit into rackmount systems. They require 2 or more existing slots to give you the same 2 or more slots back. The "ACTIVE" Riser means it expands your current bus, using an onboard chipset called a Bridge, to give you MORE slots.

2-up or 3-up - how many slots are on the new card. Remember, you will be using one existing PCI slot to plug in the Riser card, so a 2-up would give you that one back plus one more. A 3-up would give you 2 additional slots. (I only found 3-up cards)

You can do your own searches for Riser cards, looking specifically for PCI Active Riser as I did. Or, try one of these I found:
http://www.orbitmicro.com/global/rc2-019-p-686.html
http://www.rackmountpro.com/product.aspx?catid=275&prod...

Be sure to read this tutorial about Riser cards:
http://www.orbitmicro.com/company/blog/87
And this too, about which side they face A or B side
http://www.orbitmicro.com/company/blog/87/3

I think both of those cards can be turned to face either direction, but with different voltages resulting from it. And I have no idea if normal PCI use 3.3V or 5V.

Something to keep in mind. These cards are designed to use in Rack mount systems which don't have a normal case around them. The rear plate of your server case is going to be in the way and you may need to do some major redesign to use the ports on the PCI cards that would normally stick out the back. If you can use as a B facing card, you can likely just remove the slot covers and attach that way.

Good luck and I hope your client can be made happy. And tell him to feel free to email me a check!

Good find tonyn!

I got the feeling the server doesn't have any PCI-E slots either but maybe so! If it does, this would be a perfect device. It's self-contained, doesn't require possibly taking a hacksaw to the old case and provides the 2 PCI slots. And a bonus 2 PCI-E slots.

Actually, it doesn't make sense that the server motherboard wouldn't have some type of slots in addition to the two "normal" PCI slots. It's certainly got a graphics/video slot, either AGP or PCI-E x16/8, and likely at least 1 PCI-E x1 slot like needed for this external box.

And it also brings up the idea of whether the PCI cc camera adapter can't be purchased as a PCI-E card. Or one of the other existing PCI adapters in the system now.

Here's other PCI Expansion Chassis: Note some use an existing PCI, some a PCIe x4 and some PCIe x1
