Installation "home movies" on the computer?

Hello to all,
I looked at various audio kit available from attacking your computer, I mean the 2.1 and 5.1 systems. Noting that some of these kits as the Logitech Z-5400 or Creative G500 cost not less than € 220-250 as price range, I wonder if it is not at this point most convenient purchasing one of those systems sold in the store to be connected to DVD players for home-cinema.
Example there are many kit, consisting of amplifier plus 5 speakers and subwoofer, Kenwood brands type or the like, sold at places as Mediaworld at a price of 299 €.

What differences are there? May be worthwhile to buy one of these kits, and connect the computer to be used for music, games and movies?

depends on the person you wish to make in the future.

I explain, a kit like z5500 not play worse than a kit with boxes shriveled as the yamaha kenwood or indeed, the end of the story believe that the satellites of logitech are better and maybe not slightly;
But buying one of these kits as the 5.1 yamaha in the future you might change the front speakers and enjoy excellent sound, for example in a chain of electronic I found a kit of 3 boxes audiopro front of just 169 euros and not play at all evil. This especially if you plan to listen a little music.
For a start there's a nice kit in their bid at the chain, crates when you should be sufficient, however, the amplifier including harman / kardon is exceptional. well do you
the z5400 I do not know if it advisable, Satellites do not have high quality and sub closed that I think makes more noise that sound. if you want everything at once and you do not care Processed you have special needs or connections, for me the z5500 is a good compromise.

Thanks for your contribution
Which chain of distributor you referring to? A modular and expandable solution to prefer by far .... in theory once Auto construing of boxes combining tweeter and woofer, so I could see similar expansion in the future.
One problem that I can not solve is the amplification for a passive subwoofer Auto construing: I have a 38cm room loaded into a reflex granted 31Hz ... plays a marvel but the amp around to grant visas only for 5 channels, always missing the sub, which is given for "active" ...

If you hold open the way for the upgrade go on a separate system components without a second thought. For the sub ... you should also Auto construing the amplifier!
