Im goin to try build a computer and i was wondering if some one could tell me what are all the components i need and how to put them together.

After a fairly brief Google-seek I came up with these sites: (but there are many, many more out there).

I'll give you the basics what you need:
RAM
CPU, Heatsink & Fan
Hard drive
CD-ROM
Case, 300 Watt power supply
Keyboard, Mouse, Speakers
Mainboard
Floppy Drive
80MM rear case fan
Video card (if not onboard}
Sound card (if not onboard)

A good OS

Open the box your using right now, get a pen and paper.. take notes of everything you see.

Most/some CPU's come with heatsinks and fans. Some people opt for 3rd part sinks & fans.

Most/some cases come with case fans and even power supplies. Get a full tower if you can. It will make building and mantaining it a breeze.

Instead of a cd-rom get a cheap dvd-rom and a cd-writer. Theres all kinds of combinations available but i personally think a cd-writer and dvd-rom cover the basics for most users and the dvd-rom gives you the ability to view movies should you choose to. Ive watched apx 5 movies in 3 years with the PC. Its much more comfortable to watch the dvd's in the family room than at a desk.

Video & sound onboard are convenient and cheaper than purchasing seperate cards but if your a gamer or edit audio you might want to go with seperate cards.

tomshardware.com has a ton of information & reviews. Once you make your list of parts use the comparison shop link here on the right side of the screen . It locates the lowest prices on the net.

I've seen all of your other posts and I think you should buy a pre-build
