That's not a bad idea Jephree. Buying a "bare bones" system (one where the case is pre-fitted with a motherboard, processor and memory) will allow Snoozysue to fit her recently-purchased hard drive and transfer her Windows licence, saving her a bit of money, as well as allowing her the choice of purchasing whatever specific graphics card and sound card she wants
The Altec Lansing 2.1 speaker system (2 speakers and 1 sub) can be fitted into any sound card but you obviously won't get the surround sound benefits of having a 4.1, 5.1 or 7.1 speaker system. Having said that, of course, if you're happy enough with 2 front speakers and a subwoofer, then there's probably no need to purchase a separate sound card at all - just use the one that's built onto the motherboard
