Dell Optiplex 990 SFF motherboard LGA 1155/socket H2 system board D6h9t is the motherboard.

I have 2 connections left AC97, HD audio (on one connector) and USB 2.0.

The only connector that I think these could go into are the front panel (34 pins). The problem is they are 9 pins with one blank in each connector. There is no where else these can go.

Is there another adapter for this or do I pull one pin out to fit them?

Also I dont know which one goes where.

Those normally run along the bottom of the mobo. There might be a picture of the motherboard somewhere.

Check by the IO hub.

The big connector is 34 pins. The connectors are 9 pin, but I dont even know how they would fit or where they go on the 34 pin thing, but I know the usb and hd audio go there because it says it on the motherboard, but how do i get a 9pin onto that if there are no spaces and i dont know which side they go on

Your case is too new for the motherboard. Oh well. Use the audio panel in the back.
