Hmmm...
What pocessed you to buy that board? Very down and dirty basic little board. You're gonna be pretty much stuck with what you have but there are alternate routes you can go to make it work out.
First use the onboard sound. I have used and still do, C-Media products. The sound with the right speakers will rock the house.
Second if you want tv on the pc, Hauppauge makes a usb tv tuner that is good. I have an older model and it's great for the money. One model even has FM stereo radio. I gave $80.00USD two years ago and still have it. Comes with all the connectors and software.
Lastly I would install a gigabyte LAN card in the bottom slot, several massive hard drives and remote in to the system from another pc.
The slot the expanders need is called ISA and is outdated and not used on modern systems.
