Just a quick remark about the USB 3.0 front panel hub, cable is too short on a CoolerMaster Cosmos 1000 Case.
Do you know if Intel has another USB 3.0 Hub for this MB with a LONGER cable?
If there a "compatible" HUB out there in the market that could have a longer cable?
That is the only type of bracket that is being offered for Intel(R) Desktop Boards. You may need to check directly with the bracket manufacturer for testing or compatibility information.
For a list of tested hardware for this motherboard, you can refer to:
