Mainboard needed with pci-e for raid controller

[bramdo]

Hello,

I would like to buy a mainboard with ddr-2 and an sli chipset + intel s775 because I'm very happy with my components (memory, harddisks, q9450).
However, I own an adaptec 2405 card which works in a pci-e 8X slot and I need a mainboard which has a pci-e slot for this purpose (not for an additional videocard).
Are there any mainboards who are made for this purpose?

Thanks
Bram
