Need Help Upgrading Asrock P67 Extreme4 Gen3 Build

Hey guys, I want to upgrade a few things in my computer and I need your help.

This is my current build: http://www.overclock.net/lists/display/view/id/4280435



CPU: Intel Core i5 2500K @ 3.30GHz

RAM: Kingston HyperX blu 8.00 GB Dual-Channel DDR3 @ 665MHz
size: 8 GBytes

OS: MS Windows 7 Home Premium 64-bit SP1

Case: Cooler Master HAF912

Motherboard: ASRock P67 Extreme4 Gen3

Hard Drive: 360GB Seagate ATA Device (SATA) @ 5400 RPM

Monitor: Asus VE198/208 LED Monitor

Audio: Realtek High Definition Audio

Graphics: EVGA NVIDIA GeForce GT 430

Optical Drive: DVD-RW ATA Device

Power: Cooler Master Extreme Power Plus 700W

I want to upgrade to a better hard drive, and also a cooler for the CPU so I can overclock. I plan on buying the GTX 660 if it ever comes out, if it doesn't, then I'll probably get the GTX 670 later on this year. Well currently, I need a new hard drive really bad, I'm running out of space and this hard drive is so old and slow.

I am looking for a 1TB hard drive 7200 RPM. What's the best one out there that would work well with my build? I found this on newegg, but it seems that it has some bad reviews, also I am not sure if it is compatible with my build. http://www.newegg.com/Product/Product.aspx?Item=22-136-533&SortField=0&SummaryType=0&Pagesize=10&PurchaseMark=&SelectedRating=-1&VideoOnlyMark=False&VendorMark=&IsFeedbackTab=true&Page=3#scrollFullInfo

Also I want to start overclocking with my i5 2500k, this will be the first time I overclock, so I need a cooler or something. I was looking at the Cosair h100, h80, etc. Which is the best Cooler you guys think would go well with my build and my computer case. My price range below:

1TB Hard Drive & Cooler: $200 or below (I would like to stay in a $200 range). I would go a little above that $250 or so, only if it's really worth it.

BTW a nice hard drive, a cooler, and a GTX 660/670 would complete my build in the future right? What you guys think? Is there anything else I might need? BTW I'm a gamer, student, and casual PC user. I store A LOT of music and games on my PC, heavy gamer.

Thanks for reading.

Thanks for the advice jvkua.

I will be going with the Seagate Barracuda hard drive you recommended: http://www.newegg.com/Product/Product.aspx?Item=N82E16822148840

I don't plan on doing too much heavy overclocking so I think the H60 and the Hyper 212 EVO are good recommendations, but do you think the H60 would be quieter than the Hyper 212 EVO? Also I plan on adding a few more fans, maybe two Megaflow 200mm Red LED, one on the top and one on the front. Do you think that the 200mm fan would fit with an H60? Any tips for fans + cooling combination that will fit in my case best, make the least noise, and cool my system well? Like I said, I don't plan on overclocking too heavy.
