Branded or Assembled Desktop?

At WellOiledPC, we believe that purchasing a PC is a thoroughly personal decision. What you purchase could be quite different from what your neighbor purchases; what you purchase today would be completely different from what you purchased 3 years ago too!

We look at PC Purchases (excluding purchase of Software - check out our Software section by clicking the Software Menu at the top of the page, for essential software you MUST have) as a multi-stage decision process consisting of the following decisions - each one of them to be arrived at by YOU, since YOU will be using the PC!

Should you go in for a Notebook (Laptop) or a Desktop model?
If you have decided on a Desktop, should you go in for a branded desktop or a locally-assembled desktop? If you have decided to go in for a Notebook, you need to still look at 3. below:
Whether you have decided to purchase a Desktop (branded or assembled) or a Notebook, what are the specifications that you should go in for? What are the 'MUST HAVE' specifications, as opposed to the 'NICE TO HAVE' specifications? (Click these links for our recommended PC Specifications)
Whatever be your choice (Assembled/ Branded Desktop or Notebook), you would then need to get quotations from reliable vendors, for PCs that fit your specifications. This is when you need to take the final decision on which one of these brands/ models you should purchase.

If you're contemplating buying a PC (or gifting one), this is the right time - it is close to the festive season! Vendors are clamoring to get your attention with discounts, freebies and add-ons! So go get tempted! We help you choose the RIGHT Computer (Branded/ Assembled Desktop/ Notebook) for your specific needs!

This section presents you with information that will help you decide whether to buy a branded Desktop PC or a locally-assembled one.

At the very outset, our experience is that a Branded Desktop PC isn't always the better choice. Especially if you are purchasing a Desktop for your home. Consider the following facts:

A Branded PC costs about 20% more than a locally-assembled one
You can 'soup up' your locally-assembled PC (add a Graphics Card/ more RAM/ bigger and faster HDD etc.), yet, it could cost less than a Branded PC with the same Processor and Motherboard
If you already have parts from an older PC or an entire older older PC, you cannot trade it when you buy a Branded PC. Local PC assemblers usually buy back your old PC and its parts
Upgrading a Branded PC is usually costlier than upgrading an assembled PC
You might be forfeiting the warranty on a Branded PC, when you upgrade it!
With a Branded PC, you have flexible options: install a higher OS, a higher version of Office Suite, go in for a Widescreen 21" LCD Monitor, etc. You may again forfeit a Branded PC's warranty if you install a different OS or use it with parts not supplier with the PC!
With a Branded PC, you may be paying for Software that you do not really need. With a locally-assembled PC, you only pay for the software you want to install!
With a Branded PC, you may be saddled with a cheap AntiVirus/ AntiSpyware/ Office Suite or other programs. With a locally-assembled PC, you can purchase and install exactly the software you want.
Branded PC vendors may not take adequate care of you - you are a person purchasing a single (or a few) PCs - their bread and butter is large corporations that buy a few Thousand PCs every quarter! On the other hand, your local PC assembler would be keen to welcome you - YOU are his bread and butter!

Here is why the above are facts:

A Branded PC costs more than an assembled PC since assembled PC manufacturers incur lesser overheads on their products. The difference in pricing (for the same specifications) is easily 20%

It is common knowledge that upgrading a Branded PC is costlier than purchasing an Assembled PC with the same specifications. Many times, you can add more RAM (Memory), purchase a bigger hard Disk or even throw in a 3D Graphics Accelerator card and yet, pay less for a 'souped-up' assembled desktop than a desktop from a well-known PC manufacturer!

What isn't common knowledge is that you may forfeit your Branded PC's warranty, if you upgrade it after its purchase, while it is still under warranty! We have had instances where the manufacturer refused to replace a faulty motherboard because the Branded PC's RAM had been upgraded with a local (yet, respected Brand name) RAM chip! The local RAM chip continued to work just fine, it was the Motherboard that had 'died'! The logic given was that the RAM wasn't designed to run with their motherboard and therefore could have crashed it...!

With an Assembled PC, you can be a lot more flexible with your configuration. Not all Branded PC manufacturers let you install a newer OS (say Windows Vista), instead of their stock offering (which may be Windows XP), and still continue with their warranty!

With an Assembled PC, you can purchase and install exactly the software you want - you do not pay for software you do not like or do not want to use. Branded PC manufacturers would go with the best OEM offer they receive from software manufacturers, not what you need for your PC! For example, they may bundle a relatively unknown and ineffective Antivirus Solution with their PC. Similarly, Microsoft Works is commonly bundled with branded OEM Desktops. Now if you already use or have Microsoft Office, you wouldn't want to touch Microsoft Works even with a barge pole! You therefore end up paying for software that isn't the best, paying for software that isn't the one you want to use, paying for software that you already have!

Not all branded PC manufacturers have the option for trading in the standard PC part for an enhanced part. For example, you might want to go in for a 17" LCD Monitor, while the Branded PC manufacturer may be offering a 15" LCD Monitor on the standard branded product. Even where the manufacturer is willing to let you trade in the standard 15" CRT for a 17" LCD, believe us, you would be paying more money for the trade-in, in comparison with the cost of a new 17" LCD Monitor!

If you believe that Branded PC manufacturers are prompt and efficient about after-sales service, you are quite wrong! If you were the CIO of a large organization purchasing a thousand new PCs every three months or so, major PC manufacturers would be at your beck and call. For your single Home PC purchase, do not be surprised by the tediousness of getting through their Voice Response Systems, the lengthy response times and the lengthy repair times! On the other hand, if your Assembled PC vendor is the "friendly neighborhood" kind of vendor, he would be a lot more receptive to your requirements, as good, continued relationship with you means a lot more to him and his business!

PCs: Hardware, Software and Computer Services. And, People who use PCs

People seeking reliable advice for PC Purchases

People seeking advice for extracting maximum utility from their PCs

People looking for reviews of and purchase links for top-notch Security Products (AntiViruses, AntiSpyware, etc.)

Small/ Home Offices with Networked PCs, seeking maximum RoI from their IT Investments/ advice on expanding IT Infrastructure

People and Corporations planning to set up professional, contemporary, optimized, aesthetic websites

Worldwide IT Vendors looking for authentic, professional and inexpensive Market Research on global IT Markets

Software Developers wanting to Document/ create quality User Manuals for their Products/ Services

The bottom line for a home PC buyer is that you - a single Home PC buyer - are far more important to an Assembled PC vendor, compared to a Branded PC vendor. Your 1 PC constitutes perhaps 5% of the Assembled PC vendor's monthly sales (he may be selling just 20 PCs a month), whereas your single PC purchase does not even blip the radar screen of the large Branded PC manufacturer (or his distributor/ retailer), who sell thousands of PCs every month! However if you are a CIO or IT Manager purchasing PCs for your organization, Branded PCs would make a lot more sense, as it comes with comprehensive warranties and the assurance of prompt after-sales service.

So far, we have discussed some of the general issues you would face, while purchasing a Computer - Branded/ Assembled Desktop or Notebook, presented as the four corners of your PC purchase decision.

However, the specific factors you will need to confront would be factors such as Price, Service Standards of the vendor, whether the specifications you have finalized are reasonably future-proof (you would not want your PC to be incapable of running applications within 6 months of purchase!!), etc. Each of these ties in with your decision as well, thus making it a complex decision!

Here is a specific listing of such factors, with a brief explanation for each of the factors:

Subjective Factors Table:
Factor	Description
Initial Budget	Everyone has a budget in mind, while purchasing anything important. In the case of PCs too, prices vary a great deal from place to place and time to time. Again, Notebooks cost significantly more than Desktops with the same specifications
Total Cost of Ownership (TCO)	Initial price is one thing, the cost of maintaining a PC would vary a lot too, depending on whether it is a Notebook or a Desktop. Notebooks not only cost more initially, they cost more to maintain as well. You need to change its Battery once every 2 years or so and repairs will cost you more too - all of it adding to a higher total cost of ownership (TCO)
Future-proof	You may be planning to upgrade your PC (add more Memory, Hard Disk space, etc.) from time to time. On the other hand, you may be planning to use the same PC for a few years, without adding new components or enhancing existing components to it too. If you plan to upgrade (even if you don't, it makes good sense to look closely at upgradation options!), since Notebook upgrades cost significantly more than Desktop upgrades
Mobility	You could be planning to use your PC extensively, while you are on the move. On the other hand, you may be planning to use it mostly at the same spot in your home or office. In the first instance, you ought to consider Notebook more closely, while a Desktop may be better value-for-money if you do not plan to work while on the move
Power Supply	You may have clean power supply at your primary place of work, be it your home or your office. On the other hand, your primary place of work may have frequent power problems (Spikes, Surges, Black-outs, Brown-outs, Low Voltage, etc.). If you have clean power supply, you could be looking closely at a Desktop, while an irregular power supply would mean you look closely at a Notebook
Space	You might have a whole room at your disposal for your new PC. On the other hand, you might have to squeeze out space out of a crowded desk, for your new PC. If space is no constraint, a Desktop may be the better choice, while a Notebook may be the better choice if space is a constraint
Service Standards	You will definitely require professional service for your PC. Therefore, it is a good investment to ascertain the vendor/ supplier's service standards. Reputed suppliers are usually eager to provide you with a list of their customers, so that you may talk to some of them yourself. Pick up a few of these customers at random and talk to them - it would definitely go a long way towards understanding a suppliers service standards
Specs-Usage	The specifications (specs) of models vary - sometimes quite significantly. What really matters though is what you plan to use your PC for. You may be planning to use your PC primarily for simple stuff like e-Mail, Browsing, writing letters, keeping track of your personal finances, etc. On the other hand, you may be planning to use the PC for complex work like Video Editing, Engineering Design and Drawing, specialized scientific applications, etc. You could also be planning to play high-end Computer Games in your spare time. Your PC purchase decision will therefore depend heavily on what you plan to use it for
Warranty Terms	Check out the warranty terms offered by the suppliers - you never know, you may have to avail it… Notebooks come with 1 year as well as 3 years warranties, usually global. You need to clearly ascertain this, though. Desktops too come with 1 or 3 year warranties, usually local, since a desktop is not carried around on inter-continental flights.
	Notebook warranties do not cover the Batteries. Nor do they cover electric or physical damages. This is true of Desktops too
	Again, you have the option of availing on-site warranty or off-site warranty. If you go in for on-site warranty, the vendor's technicians will visit you, in case you face PC Problems. However if you have availed of off-site warranty, you will need to take the crashed PC to the vendor's service center

Obviously, all these factors may not be important to you. For example, you may not be concerned about Space requirements at all. Your neighbor, who is planning to gift a PC, may not be concerned about Specs-Usage, Warranty Terms or Service Standards as much as you would be, had you been choosing a PC for your own use. Again, while the power supply at your place of work may be excellent, it may not be so at someone else's place of work. Such factors are subjective: what is most important to you could be least important to someone else, and vice-versa!

To add to the confusion, the specifications of many of these factors are subjective (non-quantifiable) too. Perhaps the only two truly quantifiable factors in the list above are Budget (in terms of the price) and Warranty Terms (in terms of number of years of warranty). You simply cannot quantify Service Standards or Specs-Usage!

With that being the case, the Brown-Gibson offers a simple, intuitive yet accurate method for arriving at a decision. It is based on paired comparisons, with a higher preference (between any 2 factors or 2 models) being given a 1 and a lower preference being given a 0. And if a pair of factors are equally important, both of them are assigned a preference of 1.

From the Preference Table that is thus formed, the Decision Weights and the Subjective Factor Weights are determined and in the final step, the Total Weight of each short-listed model of PC (Notebook or Desktop or a mixture of both) are arrived at. The higher the total weight, the more suitable the model is, to your specific set of preferences!

To assist you with the Brown-Gibson model, we have solved a case from scratch. It explains how to use the Brown-Gibson Model, in a step-by-step manner. You are welcome to download free, the example Excel file.

Start by reading through the Tab "Legend", then go on to the other Tabs, understanding the working of the Model.

The final steps of the case are briefly reproduced below: we consider 7 Decision Factors and 5 PC models (including 2 Notebooks) in our illustrative example:

Five models of PCs (including 2 Notebooks) have been short-listed. Their Specification Descriptions with respect to each of the 7 Subjective Decision Factors are presented in the Tables below:

For the above Decision Criteria and Model Specifications, application of the Brown-Gibson Model gives the following Decision - the link above contains the complete method of solving the problem.

As per the Brown-Gibson Model therefore, the best PC and therefore the best decision is Model 2, which has the following specs:

Cost: INR 90,000/-
Core Duo, 80 GB/ 1 GB RAM, Graphics Card
Only RAM upgradable
Notebook PC with 12" TFT Screen
Small-size Notebook
Parts replacement only

Once you are familiar with the working of this model, you may create your own Spreadsheet, adding/ deleting other factors that have not been considered here - the solution process is the same, whatever be the number of decision factors or short-listed models. In fact, you may use the Brown-Gibson model for any purchase decision - automobiles, TVs, Home Theatre Systems, whatever! All that you need are;

A good grasp of how the Brown-Gibson Model works
Ability to convert your physical (subjective) factors and specifications into Brown-Gibson Preferences. In other words, you need to be able to fill in the Brown-Gibson Tables correctly

Now that you have downloaded the example Brown-Gibson Model and understood how to fill it in with your preferences and thereafter, to interpret the final solution, you are ready to apply it to your situation.
