It's a fairly OK system, but I don't think it's worth that money tbh. If you're intent on something prebuilt, have you checked out overclockers.co.uk? I used to hate them, but they've slowly won me over with some decent service over the past year.
I would prefer one smaller, faster system drive, and then one big storage drive. If you're spending megabucks, get the Intel SSD drive, that makes systems fly! Overclockers also have the 1.5tb drive for 118 at the moment.
2 CD drives is a little pointless. I have the LG GGC-H20L and it's fine for everything.
If I was going triple channel and 64bit, I'd go for 6gb of RAM tbh. (160ish on Overclockers)
All these seem pretty standard components, so it's probably going to be a bit noisy. Silent PSU and CPU cooler are the best things I've bought for my PC recently
I would also wait 'til after Xmas I'm afraid!
