Looking for a special motherboard, seen on Youtube videos

[Cereberus]

I have Mobos with 3 PCIEx16 and 3 Pciex1 or 6 cards in total. The problem is with these 3PCIEx16 near each other you can't use all the three of them, you have to sacrifice one. I have seen videos on Youtube where a guy has connected 6 PCIex1 slots with risers and that's what I am looking for, for that kind of mobo. I searched on the Internet without success. Can anyone tell me the name of the motherboard with 1 PCIex16 and 6 Pciex1 ?

you do know an x1 raiser will work in a x16 slot right? there the same thing just less pins, or you could use 3 x16 raisers and 3 x1 raisers and have all the cards off the board and spread out ( this is what most people do) or just use 6 x1 raisers on the 3 x16 and 3 x1 slots (aslong as you remember to put it at the front of the slot closest to the back of the motherboard where the USB's and stuff are)
