Hey all... it's been awhile.
Firstly (just suggestions, don't take personally), ditch the memory. PC 2700 isn't matched up to rest of the system you have laid out. Corsair is a great brand, but opt for some PC3200 or higher. Also, registered memory is more aimed towards servers and mission critical applications. So, save some money and grab non-registered, non-ECC memory. And price search through some other makers, like g.skill, OCZ, buffalo, and Patriot. They all make pretty decent RAM (OCZ is awesome).
Then, about the harddrive, is it an existing drive from your current PC, or are you buying new? Maxtors are pretty decent drives, but if you are buying new, go for the DiamondMax 10 series or higher.
Now, my next advice is completely dependant on your intentions, and it is only advice, not trying to tell you what to do. You could save a little mney on the CPU by downgrading to a 4200, and overclock it to the performance of the 4400. It shouldn't take an insane overclock to reach and/or surpass the 4400, and you shouldn't even have to upgrade your cooling.
