well the motherboard usually comes with 1 - 2 sata cables and an IDE cable so u shud be ok with that.
also does that case not come with a power supply ?
if not then i think you will need about 450 Watts minimum i would get like to be safe though
if your ever unsure on what PSU wattage u will need try this.
and jus to be safe add like 50 watts on top of whatever it tells u.
that 450 Watts was a guess but ill put ur stuff into there and see what u need exactly.
according to that u need 384 Watts so add 50 and u might as well get a 450W
my guess wasnt too far off
also if you plan on adding another hardrive or DVD drive then u mgiht need the extra
