These are from a Dell 420. My brother bought it a couple years ago, and then died a year ago. The other brother who inherited the machine isn't geeky enough to manage a windows media center system.  

They seem to be selling for around $200 on ebay, but before I deal with the whole auction thing, I thought I'd check here and see if anyone is interested. 

I'm willing to sell them separately, but would prefer to sell both to the same buyer so I only have to pack them up once.
