In this instructable I am going to attempt to show you how to build your own computer. I built this computer for about 700 with monitor. But you can build a computer for as little as 200-300 if you do it right. The lights, lighted fans and wire sleeves are not necessary but i think they look good.  I buy all my computer parts from NewEgg they are the least expensive place that I have found to buy from and if your not in a state where they have a warehouse there is NO TAX. Xpc has some great lighted accessories and it never hurts to check eBay. 

Note-The reason i don't have a graphics card is it arrived Dead and i sent it back.

To begin you will want to gather all of your parts together.
The basic computer is built from:

Motherboard - Make sure the Mobo is compatible with the processor. It provides all of the pathways connections and lines to everything.

Processor - It is like the Human Brain. Everything that goes through your computer goes through the CPU at some point.

Power Supply - A PSU converts the alternating current power from a wall outlet into a direct current power source that the devices within a computer system use. Power supplies also serve to regulate and control the distribution of this power across several voltage levels.

Memory - Random Access Memory, or volatile memory, is used by the system to store data for processing by a computer's central processing unit (CPU)

Disk Drive - Is used for reading and writing Cd's or DVD's.

Hard Drive - Used to store data and operating system.

Operating System - It manages the hardware and software resources of the system.

Computer Case - It houses the whole lot of it. It should already come with fans but you can swap them out for lighted if there not already.

Those are the fundamental things you need for a computer.

Next A little about the Motherboard.

Step 1: Going over the Motherboard.

Make sure that the motherboard you buy has the ports on the back that you want and need. Also if your still using Pata/Ide make sure it has that port as well. My mobo has both Sata and Pata.  Sorry for not showing you how to install the Processor (CPU) I had already put it on before i decided to make an instructable and i do not have any Thermal paste. You do not want to break the thermal paste seal if you do not have any thermal paste to replace it.  Please see the pictures for more information.

Please make sure all parts are compatible before buying them. Google it. or go to Eggxpert and ask them to tell you what you should buy within your budget.

nice instructable, and dont forget that you can use petroleum jelly as a replacement for thermal paste.
Thanks. Wouldn't the petroleum jelly melt and run out everywhere causing shorts?
well, from what i understand, peroleum jelly isn't conductive, abut it hasn't melted yet and i used it in my internet router. it has about the consistency of really low grade thermal paste, but i wouldn't say that it works bad, its also on my video card :)
i usually use toothpaste. works better than petroleum jelly. I read somewhere that mustard and mayo works
I actually just rebuilt my graphics card. and i used a mix of toothpaste and A&amp;D ointment.
You forgot one of the most important parts for a computer, A video card. You dont absolutely need one but if you want to run dual monitors or play games then you need one.
I put in the instructable NOTE: The reason i don't have a graphics card is it arrived Dead and i sent it back. Thank you for your comment though when my graphics card gets in i will add to the insctructable.<br>
