mk555 wrotebabum wrotei would recommend you looking for i7 compatible motherboards such as intels x58 (there are many more but look for the compatibility)
As I said I have no experience with motherboards so if you can provide me a name I will be very thankful .
babum wrotethe sound card you want to get depends on the sound system you want to use. if you are looking to use a simple two speaker system then try using the default motherboards sound card.
Yes I will use two speaker system . So I wont need to buy a separate sound card but just the motherboard ?
babum wroteCase is indeed important when building a pc, you dont want your computer to overheat and decrease its performance or suffer from sudden restarts, try looking for fanned cases with enough space for the pieces.
Of curse , what I meant is that the look of the case isn't that important .
babum wroteI would recommend you looking in tigerdirect.com for alredy built pcs with your same specs so you can see how they got them running and build a similar system.
I'm trying to stay away from already built pcs .
Yes sorry for that, try checking this GIGABYTE GA-EX58-UD3R, which is a low priced mid end motherboard, it only supports 4 ram slots and no nvidia sli, but i think it will be more than great for your purposes. try checking this website as to why choose this motherboard

Now the sound card comes included in these two motherboards so you will be fine with the default card.
respecting the casing, yes sorry I misunderstood what you were saying but what I mean with looking for alredy built systems is that you can see how they built them, what PSU unit they used, how many fans, stuff like that so that you can replicate it or have a fair idea on what to buy.
About the power comsumption, I am not able to confirm that but Im sure that any increases in power usage made by this card wont be noticeable on your bill (as they are not going to be big amounts) and it wont function at 100% of its capacity unless you are planning on playing non-stop 24/7.
I will try to give you a little example as to how you could build your computer,
mi PC is running with a 750 watts PSU, a dual core 1.6 ghz intel processor, nvidia 8800 gtx video card and 4gb ram without any problems, so i would recommend getting a psu somewhere between 750watts and 1000 watts
