Assembling a custom made computer

Saturday, May 17th, 2008

Some major computer manufacturers like Dell allow buyers to order custom built computers where they can specify the amount of RAM / hard disk space,  but there is a limited amount of  flexibility as only a finite  number of option are available.

The best custom made computers are those which are assembled by the end user or by a  reliable computer assembler who knows the applications which will be run on the computer and selects the hardware accordingly. By doing so, the user gets a computer gets the best deal at a cost effective price.

Not everyone can or even should attempt to assemble a computer themselves. Some of the minimum requirements for assembling a custom built computer  at home are as follows :

1. Intermediate to advanced knowledge of  computer hardware and assembly. You should not only be able to read and understand component specifications and assembly instructions, but also be able to fit components together and ensure that there are no loose connections.  If you are not proficient, it is advisable to hire the services of  a reliable computer technician for a few hours.  Verify the credentials of the technician if possible.

2. Tools for assembling the computer:   Magnifying glass,  small flashlight , a set of  Philips screwdrivers for assembly and needle nose pliers. An anti static wrist strap is also recommended to prevent damage to components.

Though mass produced branded computers are cheap and easily available in most countries, custom built computers can be better for certain applications / uses.

Some of  the advantages of  buying / building custom built computers are :

1. You pay only for the components and hardware you need and use. Every computer user uses the computer for different applications. Most mass produced computers have some hardware features which are not used by many users. This hardware can be eliminated, reducing the overall cost of  the computer.

2. More user friendly : For a custom built computer, there is a lot of  flexibility in selecting  the cabinet , so that USB / parallel ports can be easily accessed  and peripherals like printers connected or disconnected from the computer. Though major manufacturers like HP hire some of  the “best” designers,  USB ports for many PC models cannot be accessed from the front of  the PC.

3. In case of  component failure, you are not dependent on the manufacturer and you can use a similar component  of  any other make , if the specifications match .

4. If you use your computer for gaming, the graphics card of standard computer models may not be adequate, so it is better to custom build  your computer as per your requirements.

About custom built computers and assembly of computers.

Today, millions of computers are used all over the world in offices and homes for business and entertainment. About a decade ago  a  significant percentage of these computers were assembled, as branded computers were expensive and cost  2-3 times more than assembled computers.

However, in the last few years with increasing volumes of computers being manufactured worldwide and cost of production of the components decreasing due to improved manufacturing techniques, the cost of branded computers has become comparable to that of assembled computers.  Most consumers now prefer to purchase branded computers since the manufacturer offers an after sales warranty for a period of  at least one year (this can be extended to 3 years by purchasing a carepack) with toll free helplines.

The quality of the after sales service offered for assembled computers is often inconsistent. Due to decreasing margins, many of the  smaller dealers  use poor quality / second hand components. They may promise after sales service,  but do not respond to customer service calls. Since the volumes of the computers they assemble is low, the price they pay for each part is usually higher than what manufacturers of branded computers pay. They are also unable to carry out stringent quality control tests which larger companies incorporate in their manufacturing process.
