riser card bracket:

1. Loosen the thumbscrews (A) securing the left PCIe riser card bracket to the chassis,

then lift the left PCIe riser card bracket upwards (B) out of the chassis to detach it from

the PCIe x16 slot on the motherboard.

2. Prepare your expansion card and flip the left PCIe riser card bracket over.

3. Flip the metal bracket lock open (A) then slide the two metal brackets out of the left

PCIe riser card bracket (B) and remove them.
