Some particulars regarding this computer:
It is a regular 'desktop' computer like one might have at home although this one usually does not have a mouse, monitor or keyboard plugged into it, as it can be administered remotely. A most unusual feature of this computer is that it is not contained in a case or tower like most computers, but the components are arranged on a board, and hung on the wall. While this may not be art, it is unusual and fun. Recent major upgrade or downsisze if you will, was to migrate to a Atom Processor on a motherboard that measures about 6x6 inches!
There is now only one hard drive - a 300Gb SATA drive where web pages and other saved files are kept. Several web sites, or domains are hosted here. It was built on the cheap !

Dual Core Atom 330 (Apr '09)
Ubuntu 8.04 server edition LTS (free d ownload)
Intel BLKD945GCLF2 w/ Atom 330 ($81.99)
2 GB G.SKILL RAM ($20.99)
Apache/2.2.8 (Ubuntu) PHP/5.2.4-2ubuntu (free download)
The Precision 650 was a fabulous machine, but when I learned about the Atom and its low power consumption - not to mention low price, I thought I'd try it out. My expectations are exceeded. Uses about as much power as a refrigerator bulb and does as much as any computer in the list below. I love it : -)

Dual Xeon (Apr '08)
Ubuntu 8.04 server edition LTS (free d ownload)
2 Intel Xeon 2.0GHz Processors SL5Z9 ($21.49)
Dell Precision 650 Motherboard 2x-Xeon Socket 603 ($34.91)
Dell proprietary 460w power supply ($37.45)
1 GB RAM (donated)
Apache/2.2.8 (Ubuntu) PHP/5.2.4-2ubuntu (free download)
The 64bit setup was buggy as heck. Linux and FreeBSD both gave nothing but trouble. I wondered what might be more reliable and then I found the Xeon procs, next I went hunting for something to put them on, which led me to the Dell Precision 650 parts. Ubuntu works (as in 'everything just works') best for me. Even though I really like to fiddle, this system has potential to last years and years. (we'll see ; - )

Yet - Yet another UPGRADE !! (Jan '08)
Ubuntu Linux 7.10 Server Edition
AMD Athlon(tm) 64 Processor 3200+
GIGABYTE GA-MA69GM Motherboard
2 GB RAM
Apache/2.2.4 (Ubuntu) PHP/5.2.3-1ubuntu6 Server
As hardware has became less and less expensive, we decided to upgrade to 64-bit hardware and build a server based on this platform.
=========================================================
Yet another UPGRADE ! (Jun '07)
Ubuntu GNU/Linux 6.06 LTS
Pentium 4, 2.8GHz Processor
1 GB RAM
Apache/2.0.55 (Ubuntu) PHP/5.1.2 Server
I had a desire to revert back to Linux as I was no longer chummy with the BSD admins I once knew and had more familiarity with Linux. I'd been installing Ubuntu on our charitable distributed computers since the New Orleans Project (computerdropoff.org) so it was our distro of choice for the wall server. We tried it on SparcUltra1s and an Ultra5, a dual-Pentium III but settled on this P4.
=========================================================
MAJOR UPGRADE ! (Sep '03)
FreeBSD Unix version 5.4 replaces Fedora Linux
AMD K6 500MHz Processor has been replaced with an
AMD Athlon 750MHz Processor.
The Gigabyte motherboard is now a GA7ZX
In addition to switching to FreeBSD, a primary motivator for the upgrade is a serendipitously obtained stick of RAM, which brings the total to 768MB
Apache/2.0.55 (FreeBSD) PHP/5.0.5 Server
=========================================================
Details: (Oct '01)
AMD 500MHz processor (eBay - $22).
