mac mini g4 no wireless card

[mir2001]

I have a time capsule that I am using as a wireless router and as a wireless hard drive. I also have an imac and a windows laptop, both of which are wireless and both can stream media from the capsule. I would like to be able to stream (or at least temporarily copy over) the TC content to a mac mini which I intend to plug into my TV. I came across a cheap mac mini G4 that doesn't have a wireless card. My TC is sitting next to my tv so I was wondering if I plugged the mini into the TC via ethernet cable would the mini be able to see and copy over the media content on the TC so that I could watch it on the tv? Sorry if this question is obvious but I've only recently gone down the mac route. Thanks
