Is this motherboard, X9SCL+-F, OK to fit into SC822i-400LPB chassis?
X9SCL+-F will fit if the chassis is Revision K or later version. For this combination, you will need active heatsink SNK-P0046A4. In addition, 1x CBL-0042L (24-pin extension cable), 1x CBL-0062L (8-pin extension cable) and 4x CBL-0088L (Fan extension cable) are also necessary for extending the existing cable inside the chassis.
