the hard drive is:
1) overkill for storage. You REALLY have 2TB of data?
2) very poor. The deskstars are both slow compared to similar drives from better manufacturers (Seagate, Western Digital, Samsung) and extremely unreliable compared to the afore mentioned brands
I'd recomend either:

or

the second would be my personal choice. Both have NCQ which speeds up the drives and gives a longer average life. You can also get 2 for less than the hitatchi you posted if you want, for a total of 1TB storage and RAID0 them for faster speeds. Or, you could get 2, and use 1 as a backup drive and have them in RAID1. Or, you could settle for jsut 1 and use the money elsewhere (video card I am thinking)
For your motherboard

over what you put. Having used both boards, the asus one is much easier to use I have found, both building with it and the layout of it, and the software side of it, the bios is extremely easy to navigate and get a decent overclock going.
The CPU, for the extra $9 I'd go for

for the higher clocks and because you can change the multiplyer, making for easier and better overclockability if you wish to do so in the future
for $25 extra (potentially saved on the hard drive

)

would be a much better option for the video card. The 9800GTX+ is the exact same card as the GTS250, both of which are destroyed by the 5770
