Tech Friday: Building Desktop Computers from Scratch

I know. This violates the rule of “stay of out the hardware business”. But I am search of a smaller computer, I have decided to try building one using components purchased from NewEgg and Crucial.

Eventually this may turn into a desktop machine. I looked for an attractive-looking case, and ended up getting the ASUS Pundit-R partly because it looked so attractive. The price was right at about $165.00 for the case. The case comes with a motherboard suitable for a Pentium 4 processor, and up to 2 gigabytes of RAM. The motherboard also comes with video connectors and apparently these systems are being used to build digital video recorders, or what I’d call a “poor man’s Tivo”.

Such systems are called barebones computers, and if you do a Google search on these, you’ll find a lot of comentary about them.

I got the Pundit-R case by itself, without any other components. Just for grins, I plugged in the power supply, and found that the thing sounds like you are standing next to a jet engine. Absolutely the loudest thing in the room. However, there is supposed to be a way to throttle the fan back, so I’ll I will reserve judgement until the system is built.

I ordered a Pentium 4 processor, a megabyte of RAM, a CD-ROM and a hard drive for the unit. We’ll have to see how it all goes together.

The most popular SFF boxes today from Shuttle, MSI, and Biostar are all of similar size, having roughly square dimensions in height and width and being somewhat longer. This fits a small power supply of 200 to 250 watts and gives enough room for a 60mm or 80mm fan in back for system and CPU cooling. A back panel full of VGA, USB, ethernet, sound, and firewire connectors provide a complete set of expansion opportunities. The front panels usually have USB, Firewire, and audio ports for additional expansion. Custom or semi-custom CPU heatsink/fan combinations are provided by most makers, with the most notable being Shuttle’s heat-pipe with an 80mm exhaust fan. Two expansion slots, usually one AGP and one PCI, makes it into most SFF systems. Vented side panels help keep high-end video cards cool, and the expansion slots usually have room for full height cards so that the latest high-end video cards will fit.

The Practice of System and Network Administration

by Thomas A. Limoncelli and Christine Hogan

This is an important book. It provides an exhaustive analysis of the problems and practices of maintaining an extensive IT infrastructure from the desktop computers, to the network, to the server room. It covers staffing, discusses the “help desk”, budgeting, inventory management, and security. For those who are perplexed about Active Directory, there is an excellent discussion of name spaces and DNS. This is a book for the techies, their technical supervisors and their managers. Managers: if you want to know what the hell your computer support staff are supposed to be doing each day, it is in this book.

From the Preface:

… These six pinciples are recurring themes in this book.

  • Simplicity means that the smallest solution that solves the entire problem is the best solution. It keeps the systems easy to understand and reduces complex interactions between components that can cause debugging nightmares.
  • Clarity means that the solution is not convoluted. It can be easily explained to someone on the project or even outside the project. Clarity makes it easier to change the system, as wellas to maintain and debug it.
  • Generality means that the solution solves many problems at once. Sometimes the most general solution is the simplest. It also means using vendor-independent open standard protocols that make systems more flexible and make it easier to link software packages together for better services.
  • Automation is critical. Manual processes cannot be repeated accurately nor do they scale as well as automated processes. Automation is key to easing the system administration burden, and it eliminates tedious repetitive tasks and gives [System Administrators] more time to improve services.
  • Communication between the right people can solve more problems than hardware or software. You need to communicate well with other SAs and with your customers. It is your responsibiltiy to inititate communication. Communication ensures that eeryone is working toward the same goals. Lack of communication leaves people concerned and annoyed. Communication also includes documentation: document customers’ needs to make sure you agree on them, document design decisions you make, document maintenance procedures. Documentation makes systems easier to maintain and upgrade. Good communication and proper documentation also make it easier to hand off project and maintenancde when you leave or take on a new role.
  • Doing the basics first means that yo ubuild the site on strong foundations by identifying and solving the basic problems before trying to attack mre advanced ones. Doing the basics first makes adding advanced features considerably easier, and it makes services more robust. A good basic infrastructrue can be repeatedly leveraged to improve the site with relatively little effort. Sometimes we see SAs aat other sites making a huge effort to solve a problem that wouldn’t exist, or would be a simple enhancement, if the site had a basic infrastructure inplace. This book will help you identify what the basics are and show you haow the other five principles apply. Each chapter looks at the basics of a given area. Get the fundamentals right, and everything else will fall into place.

Thunderbird: OutLook Express Replacement

The Mozilla developers have released Thunderbird, an open source, (free) replacement for Outlook Express which will run on Windows, Macintoshes, and Linux desktop computers. Those who use the Netscape Messenger eMail program will feel right at home. Screenshot

One possible misconception about the program; it is not a replacement for the full-blown Microsoft OutLook. It does not include a calendaring program, and it does not integrate with Microsoft Exchange. Thuderbird is an attractive modern replacment for OE. But wait! There’s more! Check out the feature list.

Less painful instant messaging with GAIM

One objection I’ve always had to instant messaging is that all of the free programs available for doing this had numerous bells and whistles, as well as adware, spam, pop-ups, noises, animation, and whatnot. A second problem has been that the various systems don’t all talk to each other. Still, there are legitimate applications for IM. A nice “quiet” version of an IM client is the GAIM client. This works with AOL instant messaging, Yahoo, IRC, and Jabber, among others. It can also work with multiple systems simultaneously.

We are using IM for real-time chat during video conferences between the master control room and the sites in the field. It allows a short quick message from one site to another; ‘Raise the mic volume in Springfield! or ‘What number am I supposed to dial?’ Since the majority of technicians had AOL accounts, it was simple just to get another and assign it to my GAIM client.

Buy Cheap Software at buycheapsoftware.com

For those who are not in the education market, and who are not buying multiple software licenses buycheapsoftware.com is a reliable source. Recent pricing:
Windows XP Professional with Service Pack 2: $138.00
Norton Antivirus, retail version $39.00
Office Small Business $219.00

They offer “OEM” versions of software, meaning just the disks without retail packaging or documentation. This is the software that would be included by a dealer when shipping a new machine.

Free System Profile Program

If you have a few idle moments… check out the free system profiler at Belarc. Tells you everything you want to know about your computer. (How do they do it? It looks as if it mines the Windows registry.) But there are all kinds of interesting things including the model and capacity of your hard drive, and memory.

The free download is for individual use only, nor for your organization. A corporate version is $19.95/year ($399 minimum) i.e. for 20 machines. This allows you to use a web-based application to create a profile for your machine.

Onfolio integrates with FoxFire & has NewsFeed Reader

The latest beta version of Onfolio now integrates with the FoxFire web browser (on Windows machines). An added bonus, it also contains a newsfeed reader which seems to be a substantial improvement in functionality and appearance over my last current favorite, Sharpreader

As an organizer, a reporter, and now a newsfeed reader, Onfolio, in its latest incarnation really deserves a look.
