any suggestions/recommendations? (my computer build)

[geo8o2]

i already have this:
-COOLER MASTER Centurion 5 CAC-T05-UW ATX Mid Tower Computer Case (http://www.newegg.com/Product/Product.asp?Item=N82E16814150098)
-XFX GEFORCE 6600GT (http://www.newegg.com/Product/Product.asp?Item=N82E16814150098)

so how's this to add to it:
-ASUS P4P800SE ATX Intel Motherboard (http://www.newegg.com/Product/Product.asp?item=N82E16813131484)
-Intel Pentium 4 3.0E 800MHz FSB Socket 478 Processor (http://www.newegg.com/Product/Product.asp?item=N82E16819116171)
-CORSAIR ValueSelect 2GB (2 x 1GB) 240-Pin DDR2 SDRAM Dual Channel Kit System Memory (http://www.newegg.com/Product/Product.asp?item=N82E16820145527) -Western Digital Caviar SE 80GB 3.5" Serial ATA150 Hard Drive (http://www.newegg.com/product/Product.asp?item=N82E16822135106)

this is my first build..
is the hard drive good enough? do i need a fan/heatsink?
am i missing anything?

will be for multitabling party, no more than 8 tables. most of the time i just stick with 1-4. will start using PT more often. i want to be able to play games(non-poker) as well. maybe even at the same time. i do have 2 monitors.

any suggestions/recommendations.. ty in advance.

if(i have no idea if i need one or don't)i do need a fan/heatsink how's this one: Thermaltake CL-P0114 120mm Cooling Fan/Heatsink (http://www.newegg.com/Product/Product.asp?Item=N82E16835106061)

also are there any compatibility issues with any of products ??

Hard drive might be a bit small. Depends. The Western Digital SE drives with 8mb cache are nice, and the price is probably right. think the smallest one 120GB.

Check to see if your processor is a boxed or OEM. If it's a boxed processor it will have the fan/heatsink included.

Thermaltake are pretty good heatsinks and fans. Some of those bigger heatsinks may have clearance issues with your case and/or might be heavier than intel recommends (and may void your warranty.)
