Help me choose a combo RAM+CPU+mobo

Hi, Dad says they want to build a PC at work for floating point calculations. He says they only have to buy
RAM
CPU
Motherboard

Budget: $400-450.

Ideas? I think the best choice would be Intel Core Duo? By the way there will be zero over clocking and no gaming. I think it is a plus if motherboard will have on board video...
Thanks!

Intel E6300
2GB of value DDR2-667ish.
Cheap Arse motherboard.

is RAM very important?
Maybe something like this:?
E6300
1gb RAM
decent motherboard

I am afraid of stability issues.
