Configuration help

Below please find my proposed configuration, the items I'm clueless on are.

The case, I pick one at random, concerned most about noise is an overriding issue. I will be using LC and will OC. If I add extra fans again I'm concerned about noise level but I'm willing to add fans if warranted. If fans added which ones and how many? to minimize the noise but do a decent job cooling. 

MOBO again picked one at random any suggestions?

Will plug RJ45 from cable modem into port on rig but I read about wireless card. I either have to add a wireless router for our home laptops or can I do the same thing with this wireless card? and which option is it? But I do want to have the desktop plugged directly into the cable modem for purposes of speed.

Many thanks.

Thanks for the configuration, some additional information the kids will be watching Blu-Ray disks on a Samsung 30 inch display the 305T Plus. I  wasn't sure a single graphics card would handle the load of 30 inch. Also still wondering about the case if the one suggested is the "quietest" or what was the reason for it's selection?

Many thanks for your time.

Thanks, very good answer, the first time I missed your note about about the faster HDD's. Plus the only gaming will be flight simulator, formula one racing simulator and maybe call of duty. Sounds like a single 295 GTX will be more than enough.

Only other concern is Vista is a 64-bit OS so it can address up to 8gig, do you think six will be enough? of course my current XP machine has 512k.

Thanks for the excellent suggestions they save me a decent amount of money.
