If any one is looking for surround speakers for their computer, I have bought 2 sets of these from PC World at £59.99 each.(One for my son's Xmas present, and I was so impressed with the quality I have bought a set for my computer) They are fantastic quality, with THX certified 50w speakers with removable covers and a huge 200w base speaker, but no central front speaker. These were reviewed as outstanding when they were £199, even now the same base speaker and 2 front identical speakers as a 2:1 system cost £149 at PC world. Presumably discounted as not 5:1, but fantastic value nevertheless. Cheapest on line price I have seen is £160, they are to be found if you are lucky near the speaker section but probably with no price near them so they are not selling as they look expensive!
