Whats a good motherboard?

For the second option there is audio port so that mean I wouldn't have to by sound card
Because I want my desktop to have wireless network adapter
So where would i put wireless adapter at then
 
Well, both motherboards have a built-in sound card, so you wouldn't have to buy a sound card for either of the systems unless you want better quality. As for the wireless network adapter, if you have a USB adapter, you just plug it into a USB port and install the drivers
