Wanting to upgrade my PC

[mark1984]

I would like to know if upgrading my PC would just be a case of taking the old stuff out and plugging the new stuff in without having to format the hard drives, etc

At the moment I have:

Motherboard: Soyo V6BE
Processor: Intel 500 MHz Pentium III with 512k ECC L2 cache
Graphics Card: GeForce 2 MX200 32MB
Memory: 640MB SDRAM (1x 128MB and 2x 256MB)

and I want to upgrade to:

Motherboard: Asus P4B533-E Audio/Lan/Raid
Processor: Intel Pentium IV 2.4GHz 478Pin 533MHz 0.13u Retail
Graphics Card: Inno3D GeForce4 Ti4200 128Mb DDR DVI TV-Out AGP
Memory: 256MB DDR PC2100 RAM

Also I would like peoples thoughts on what type of Cooling/Heatsinks/Fans I should get.

Thanks
