Help choosing a Hi-Fi/ Speaker System?

I need to buy a decent Hi-Fi/ Speaker system soon but I need it to have Bluetooth so I can use it with my iPhone, it also needs to have an input so I can plug my pc sound into it. Does anyone know one with these features on eBay (available to Australia) that doesn't cost too much. Not too loud 25 - 100 watts RMS is fine.

Also how do I link it up to my computer I.e. Do I need a sound card, what cables do I need? I'd rather not have to buy a sound card if possible, maybe I can just use the motherboard outputs?

Id rather that it was 2 speakers so I can put them each side of my tv with a small control box or something (if this even exists?)

Any advice is appreciated, thanks.

My advice would be to visit audioengine.com they have a section that explains your very good questions and how their products are a solution. They are not the only game in town but they do explain who wireless speakers work and so forth. Adam and Vanatoo are very good wireless speakers not knowing your budget these three suggestions will not disappoint.

Without stating a budget, you may as well just type random characters.

Donno. My solution is to buy a phone that does not ask I buy everything else in my life to suit it. Phone, 50 -100 dollars. Receiver and speaker system, $1500 or more dollars, at minimum. Independence from stupid cheap handheld technology, priceless.
