1.4 Building or Buying a PC

1.4 Building or Buying a PC



The make-or-buy decision is a fundamental business-school concept.
Does it make more sense to make a particular item yourself or just to
buy it? With entry-level PCs selling for less than $500 and fully
equipped mainstream PCs for $1,200, you might wonder why anyone would
bother to build a PC. After all, you can't save any
money building one, can you? Well, yes you can. But
that's not the only reason to build a PC. Here are
some more good reasons to do so:



Choice


When you buy a PC, you get a cookie-cutter computer. You may be able
to choose such options as a larger hard drive, more memory, or a
better monitor, but basically you get what the vendor decides to give
you. And what you get is a matter of chance. High-volume direct
vendors such as Gateway and Dell often use multiple sources for
components. Two supposedly identical systems ordered the same day may
contain significantly different components, including such important
differences as different motherboards or monitors with the same model
number but made by different manufacturers. When you build a PC, you
decide exactly what goes into it.



Component quality


Many computer vendors save money by using OEM versions of popular
components. These may be identical to the retail version of that
component, differing only in packaging. But OEM versions have several
drawbacks. Many component vendors do not support OEM versions
directly, instead referring you to the computer vendor. And OEM
versions often differ significantly from the retail-boxed version.
For example, Dell has used modified versions of standard Intel
motherboards. That means owners of those systems cannot use Intel
BIOS updates. Instead, they must depend on Dell to provide an updated
BIOS. Dell and other major makers sometimes use downgraded versions
of popular products梖or example, a big-name video card that
runs at a lower clock rate than the retail version. This allows them
to pay less for components and still gain the cachet from using the
name-brand product.



Cost


PC manufacturers aren't in business for charitable
reasons. They need to make a profit, and that means they need to sell
computers for more than they pay for the components and the labor to
assemble them. Significantly more, in fact, because they also need to
support such expensive operations as research and development
departments, toll-free support numbers, and so on. But PC
manufacturers get huge price breaks because they buy in very large
volumes, right? Not always. The market for PC components is extremely
efficient, with razor-thin margins throughout. PC manufacturers may
get the hard drive that costs you $75 for only $70, but
they're not going to get it for $50. They may even
have to pay $80 because PC manufacturers often have long-term
contracts with suppliers. That can work either to the benefit or
detriment of the PC maker. When the price of memory is plummeting,
for example, a PC maker may have to pay twice as much as you do for
memory. Conversely, when the price of memory skyrockets,
you'll pay the spot price, while the PC maker may
pay only half what you do because its memory suppliers are selling on
a long-term contract price. Our rule of thumb is that, on average and
all other things equal, you can probably build a midrange PC yourself
for about 75% to 85% of what a major manufacturer charges.



No bundled software


Most purchased PCs include Microsoft Windows, Microsoft Office, or
other bundled software. If you don't need or want
this software, building a PC allows you to avoid paying for it.





OEM software is one of the best-kept secrets in the direct sales
channel. It isn't advertised, and no one tells you
about it unless you ask. If you buy a motherboard or hard disk and
need this software, ask the vendor if they can supply it. Note that,
although OEM versions of Windows and Microsoft applications are often
labeled "For sale only with a new
PC," Microsoft has in the past taken a liberal view
of what constitutes a new PC. Buying a hard drive or a motherboard
may entitle you to buy an OEM version of the software you need at a
greatly discounted price條ess, in fact, than
you'd pay for a retail upgrade version. Microsoft
has tightened eligibility requirements for OEM software, though, so
make sure any software offered with a motherboard or hard drive is in
fact an authorized version.



OEM software prices are striking. For
example, when we checked prices for a motherboard for a new system in
June 2003, we could have purchased with that motherboard a full OEM
version of Windows XP Home Edition (full version, not upgrade) for
$68, a full OEM version of Windows XP Professional for $115, or a
full OEM version of Office XP SBE for $158. Full OEM versions are
generally about two-thirds the price of retail upgrade-only versions,
so if you need the software, this is a cheap way to get it. Of
course, Microsoft doesn't support OEM versions,
which is the main reason for the low price. But then, some might
argue that Microsoft doesn't support retail versions
very well either.




Warranty


The retail-boxed components you'll use to build your
own PC include full manufacturer warranties which may run from one to
five years or more, depending on the component. PC makers use OEM
components which often do not include a manufacturer warranty for the
end user. If something breaks, you're at the mercy
of the PC maker to repair or replace it. We've heard
from readers who bought PCs from makers who went out of business
shortly thereafter. When a hard drive or video card failed six months
later, they contacted the maker of the item, only to find that they
had OEM components which were not under manufacturer warranty.



Experience


If you buy a computer, your experience with it consists of taking it
out of the box and connecting the cables. If you build the computer,
you know exactly what went into it, and you're in a
much better position to resolve any problems that may
occur.





Although there are many advantages to building a PC, there are some
offsetting advantages to buying one instead, including:



Time


Building a PC takes time, not just the time actually needed to build
it, but also the time required to choose and order the components. If
you're building your first PC, expect to spend at
least a day selecting and ordering components and a weekend actually
building it. We maintain web pages at our web site, http://www.hardwareguys.com, that list our
picks for the best components for various types of systems, from
budget to high-end.



Integration


When you build a PC, you are responsible for
making sure all components are compatible, locating and installing
the necessary drivers, and so on. But this isn't as
onerous as it may at first appear. With very few exceptions, PC
components simply plug together and work, just as any VCR works with
any television.



Component availability


If you absolutely need to have the latest,
greatest CPU or whatever, you may have no choice but to buy a PC that
includes it. Like in any other business, component makers favor their
major customers, who happen to be the large PC makers. When the Intel
Pentium 4 processor first shipped, for example, you
couldn't buy a retail-boxed Pentium 4 for love or
money. If you wanted a Pentium 4, your only option was to buy a PC
with a Pentium 4 in it because essentially 100% of Pentium 4
production was going to the PC makers. If you're
considering buying a PC for this reason, we suggest you think again.
It's almost never worthwhile paying a significant
premium for the latest and greatest, let alone buying an entire PC to
get it.



Support


If you build a PC, you become Support
Central for that PC. There's no single manufacturer
to call, and it's up to you to figure out where a
problem lies. If you isolate the problem to, say, the motherboard,
you'll have to talk to the motherboard maker
directly, assuming that they'll talk to you. Some
will not, notably including Intel. You also may have to deal with
multiple vendors all claiming that it must be the other
guy's fault. Of course, just because you bought a
packaged PC doesn't guarantee that the maker
provides good tech support. Some makers are famous for consistently
excellent support (although, according to many of our readers, even
the best manufacturers' support quality has waned as
PC prices have dropped). Other makers are more variable, sometimes
providing top-notch support and other times not. Some makers provide
better support for corporate users than for individual buyers. Still
other makers provide infamously bad support to all comers.



Bundled software


If you don't need
bundled software, there's no sense in paying for it.
But if you do want the software bundled with new PCs梩ypically
Microsoft Windows and Microsoft Office梱ou'll
be hard-pressed to find a full retail version for anything near as
little as it actually costs you as part of a new PC purchase. On the
other hand, as noted earlier, OEM versions of the software are often
available at very low prices when you buy a disk drive or
motherboard.
