That's a lot of RAM

Though I guess the price isn't too bad. Haven't used that exact brand yet, so can't comment on the quality.
Do you actually need that amount of RAM?
EDIT: Buying it from Rectron I suspect, only noticed it on their price list now
EDIT2: Small point, but it's DDR2-1066, not DDR2-800. Make sure your motherboard supports it, otherwise it'll only run at DDR2-800 speeds. And with DDR3 and the motherboards that support it steadily becoming cheaper, I wouldn't spend that amount on DDR2 RAM right now.
