I'm starting to think a 2.1 system would probably be sufficient for my purposes, and cost far less.
The system would be in my bedroom, connected to my pc. I've got two 23" wide screen monitors, so I'd just watch a couple movies/listen to music/play games.
Source would therefore be the optical out from the on-board soundcard on my motherboard (gigabyte ud5).
I wanted to get the 5.1 as I was imagining it could be useful within 2 years or so when/if I get myself a proper tv. Might be better for me to just get some bookcase speakers and get a nicer HT system when I need it/have a bigger budget...
Any suggestions for decent quality/relatively cheap speakers then? A 2.1 or even 2.0 would probably suffice...
