Will a PCIe 1x work on this slot?

I bought this mobo:
Intel SE7520BD2
http://www.intel.com/cd/channel/res.../server/boards/dp/se7520bd2/feature/index.htm

It has these 2 PCIe slots:
1 X PCI Express X 8; 1 X PCI Express X 4

Here is a pic of the mobo:

It would be the 2 black slots.

Did they even make a 4x or a 8x card? Would a 1x card work? I don't want to use the on board video since its an ATI Rage with only 8mb of ram.

Depending on the case you're putting that in, you could just get a decent low profile card, attach it to the card cage, then use a x8 to x16 cable adapter. I was shopping for x1 cards a while ago, and boy, are they expensive! The adapter + x16 card is probably a cheaper path, and one with more options too.

You can actualy break the end open (carefully) of the PCIe slot (The one that doesnt line up with that southbridge heatsink) and drop any PCIe gfx card into it that doesnt interfere with anything on the motherboard physicaly

For a better understanding of PCIe card sizes - and understanding the implications of slot size vs. connectivity, and of compatibility, you might want to see the PCIe cards tab at Upgradevideocards.com :

Cutting the slot is a good idea if its a really low power gpu. If the Gpu comes anywhere close to 45w you should not do it. If it doesnt get enough power the Gpu will not remain stable under load.

Whats the use for this thing gonna be? Home server?

The only thing I can think of as a reason to use the PCIe slots there is if you'd be trying to do some gaming or watching hd video. You should be able to get away with a cheap PCI card and set it to default in the bios, if the only desire is to get a better resolution.

Another way to look at it is to dremel or file the actual pci-e x16 video card itself, rather than the slot. It takes some patience, but it works. I'd recommend sticking with really low-end cards like HD5450 though.

The only reason I can see for using gfx in the PCIe slot is that the onboard Rage gfx are unsupported by newer OS's, Not to mention not enough gfx memory for any decent resolution.
I tried the same thing on a simular board with Win7, Sadly it didnt have the PCIe slot, Only PCI.

Problems I ran into trying to run Win7 on a duel soc 604 (400Mhz FSB) board were-
1. For some reason HT would lock the system hard Durring boot, But left it off since the the NB couldnt handle that much bandwidth anyways.
2. Rage GFX are unsupported by Vista or newer since they require DX9 or higher, Couldnt find a PCI card that supported DX9 (Really didnt look hard)
3. Duel Soc 604 (400) doesnt support power management.
4. FBDDR singlechannel is extreamly slow.

Suggestion,, If you are just tring to upgrade a system you already have then cutting the back of the slot is best
If you are atarting from scratch you would be totally wasting money when newer modern day hardware is cheaper and so much faster.
