The following table is a list of items that can be used to build a PC. The comment section is deliberately brief because individual requirements can vary widely. Buying the latest/fastest version of any PC item is not usually worth while. If you want a PC for general purpose use you will find that buying one that runs at only half the speed of the fastest available will generally cost lest than one quarter the price. General business and internet work can be carried out on a very modest PC. Anything that runs at 200 MHz or faster is good enough for most people. Many users manage quite well using even slower PCs. Games fanatics need deep pockets to keep up with what is available. A fast processor and a brilliant video card can provide excellent moving effects in games these days - at a price! However, games and serious work on the same PC do not often work very welll together. It is best to use an older.slower PC for serious work and to have a separate faster PC for action games.
As a rough and ready guide you can buy next year for £60 what costs you £100 this year. Prices are always falling for the same performance or functionality is always improving for the same price.

There is very little choice of operating system these days. Most modern programs require at least Windows 95 and some need Windows 98. However, there are a lot of incredibly usable and useful programs around that will work well and fast under the old DOS and Windows for Workgroups 3.11 operating systems. Windows 2000 will only run 32-bit software that has been approved by Microsoft.
I never recommend any Microsoft product to anyone when there is an alternative available that will do the job better. I refer to Linux elsewhere in these pages and I advise you to consider using Linux if you need more security and reliability than Microsoft products can offer. Although Microsoft Word has become a sort of standard in wordprocessors it is clunky when compared with Corel Wordperfect or Lotus Wordpro. Both of these can be obtained in Windows and Linux versions. Word has been the subject of several virus attacks. The other wordprocessors have had no problems. Microsoft Internet Explorer is much less secure than Netscape and cannot handle the security firewalls used in credit card transactions properly. Internet Explorer is always totally open to external modification by web sites or totally closed. Netscape allows a special code to erect a secure interface for credit card transactions while remaining closed to other modifications.
Almost all business requirements can be catered for under Linux and there is a lot of other Linux software available to suit almost every taste. Any part of Linux can be downloaded from the internet free but it is often more convenient to get a Linux operating system from one of the many Linux distributors on a set of CDs and to pay a modest amount for the service.
When contemplating software to run under Windows 95/98 beware of anything bundled with a PC. Most of the stuff will be tried a few times and then ignored for ever afterwards. Good names to look out for include Adobe, Norton/Symantec, Corel and Lotus. There are others who produce good specialised software but a careful check of what is available for a specific purpose will soon lead you to what is really usable and worthwhile.
A Sad Story
Some years ago when I was running a small business selling computers
I was asked to quote for a reasonable 486 PC. The customer discussed
the price with his wife before telling me that he could not buy
from me without hire purchase. He could not raise enough cash
at once. He went to Dixons to buy a computer because they could
provide a hire purchase service.
About a week later he came to me and said: "My new computer
starts up OK but it does not seem able to run anything.."
When I checked I found that it had only 2 megabytes of memory
fitted. Memory was expensive in those days so I assumed that it
would not be difficult to upgrade his PC with another 2 megabytes
to enable it to run programs like Word and Excel. I got two 1
megabyte 30 pin SIMMS to do the upgrade for him. When I got the
computer to do the upgrade I found that it had been fitted with
one of the very new (at the time) 72 pin SIMM modules. There was
only one SIMM socket on the motherboard. The only way to
upgrade the PC was to throw away the 2
megabyte SIMM that had been fitted and replace it with a 4 or
8 megabyte 72 pin SIMM.
(4 megabytes cost around £90 in those days so wasting 2
megabytes was not a trivial matter.)
In these days when it is customary to have 32 megabytes or more
memory in a PC it is had to imagine what it was like to run a
PC with only 4 megabytes of RAM. However, software did not need
so much memory then. Microsoft had not progressed to the current
fashion for bloatware. 2 megabytes were needed to run Windows
3.11 for Workgroups and most programs then available would run
in another 2 megabytes.
You can gather from this that any computer sold with only 2 megabytes
fitted (and Windows 3.11 for Workgroups installed) was effectively
useless. Only the worst of despicable money-grabbing companies
would produce and sell a PC that would be impossible to use by
a total newbie. The company that made that PC was PACKARD BELL!
Now, whenever someone asks me about what PC to buy (and where
to buy it) I have a ready-made answer for them. Guess what I tell
them?
I have included this piece as a warning to all would-be buyers
of a new PC.
If you want to buy a new PC, don't buy one from a company where
the shop assistants are more interested in the commission that
they will earn than providing what the customer needs. Beware
of anything "bundled" with the PC. If it is hardware
like a printer or a scanner you can be sure that it is likely
to be either a discontinued model or one that is a non-seller
because of its deficiencies. If it is software that is bundled
with the PC you can be sure that it is not what you would like
to buy if you could choose.
Finally, beware of "Corporate" PCs. These are made to
suit companies that require ten or more identical computers. If
one fails it can be replaced by a new identical model. The
snag is that these PCs have many custom-made parts that can only
be obtained from the PC manufacturer - at a price that will shock
you. Generally speaking these PCs cannot be upgraded. All
of these "Corporate" PCs are made by big name companies
like Apple, Compaq, Dell, Hewlett Packard, Packard Bell and IBM.
In the PC trade these are known as "Dead End" PCs because
they just get more and more out of date as time goes by.
When they are new these PCs seem to be OK and they are. However,
from then on it is all downhill.
An anonymous PC uses parts that fit together as easily as Lego
bricks. Upgrades are always possible at a modest cost. To
a degree it is better to get as big a case as possible so that
there is room for more items to be added later.
Buy the complete computer or the upgrade parts from a Computer
Fair (prices are generally cheaper) or from a small high street
shop that is not a part of a chain of stores. You will get good
service from someone who really knows what he (or she) is talking
about. The seller will want you to come back for more so he or
she will be as helpful as possible.
Note:
All traders at Computer Fairs are covered by the same trading
laws as high street shops. In addition, Computer Fair organisers
will blacklist any trader who causes trouble to customers. Most
British Computer Fair organisers will circulate the name and details
of any trader who is blacklisted by one of them. They all want
to have happy customers and none of them want Computer Fairs to
get a bad name.
I condense my advice about buying a computer down to one sentence:
