there is no amd 2800+ based on the socket 939 so the asus a8n-e mobo cant be used.
check here,

the hynix ram may not be available that cheap , min i think is for 2500-2700/-
@prem
what is the purpose of your new pc ?
budget is very very less for gaming though you can build a decent celeron based system.go for a ram which offers warranty like zion or something.also if u dont intend to use it for gaming then 256 mb of ram is sufficient.
for value gaming go for a amd 64 (754 pin ) 3000+ or 2800+ (if available , now d/c) with an asus k8n-e deluxe mobo. take a 80 gb sata hdd.
alternatively you can try
celeron 2.4 + intel orig 865 + 256 mb ram + 80 gb sata + liteon cd-rw + ibox cabinet + logitech value combo + 15" crt (lg/samsung/acer) etc
it will cost around 20 k then.
