Hi,

I have a 1RU rackmount server chassis and i am having trouble fitting a 
3Ware RAID IDE card [RC-7506-4LP] [with riser card] to a Supermicro 
Mainboard.

It does not seem to have the necessary clearance from the PCI slots on 
the MB to connect the IDE cables to the 3Ware card once the cables are 
connected.

hardware:

Chenbro CSPC-115b 1RU rackmount server chassis
3Ware RAID IDE card [RC-7506-4LP]
JM103 PCI-X riser card
Supermicro Mainboard [P4SCI]

i have pics of all.
