nvidia 630i rs 6100
core 2 quad q8400 2.66ghz rs 15850
250gb hard rs 4000 maximum
CORSAIR XMS2 TWIN(1GBx2)DUAL MEMORY KIT rs 4800
power suplly 450-500 watts rs 3500-4000 ( 4500 with casing n 460 Watts PS*RECOMMENDED*)
but i would recommend u to buy a casing plus power supply deal from galaxy computers which will cost u about 4500 for both things 
given below are the links of casings n u'll get cooler master 460W power supply
* but remember one thing that if u want to buy high end graphics card than u will have to buy a power supply of atleast 620Watts....till Nvidia GTS 250 PS of 420 Watts is good to go...but if u buy GTX260 or above than u will have to buy 620 WATTS coz m running my pc on 500Watts n i think its putting burden on Power Supply...
total is 35250 with the deal of CASING + POWER SUPPLY n motherboard has a built in VGA so in the mean time when u collect some money for VGA u can at least run ur computer to get satisfaction
all the rates have been taken from galaxy computers n i think u should buy the things from them they are good 
Motherboards - nForce® 6 series - nForce® 630i
