2007.01.01 update: The standard workstation needs updating for the latest generation of Athlons. The Core 2 Duo is an interesting alternative but seems slightly too expensive for its performance.
To install the operating system you will need a CD with ``ISO image'' ubuntu-5.10-install-amd64.iso (MD5 checksum 7fbe948be484ba2f4740ab6113890652). You can order this CD from Ubuntu for free; or you can create the CD using a computer that has an Internet connection (to download the ISO image), a CD burner, and a blank CD.
To configure and use the standard workstation you will need a keyboard, a touchpad/trackball/mouse, a monitor, and an Ethernet cable attached to the Internet. Collect this equipment for later use.
If you have only one keyboard, mouse, and monitor, and you need those to operate an older computer, you have two options:

Variant: single-core CPU. The Athlon 64 X2, like a dual-CPU computer, has two processing cores. Switching to a single-core computer means spending less money on the CPU (currently $152 instead of $322). Of course, this also reduces the computer's speed for parallelizable operations.
Non-recommended variant: Pentium D. Switching from the 2000MHz Athlon 64 X2 to the 3000MHz Pentium D 830 (and a Pentium D-compatible motherboard) doesn't change cost noticeably: it means spending slightly less money on the CPU and slightly more money on the motherboard. Most applications are faster with the Athlon 64, so I don't recommend this switch.
Variant: more memory. You can put four DIMMs into the A8V.
Non-recommended variant: non-ECC memory. Make sure to buy ECC DIMMs. I have a separate page discussing the importance of ECC memory.
Variant: more disk space. If you have more money to spend, the hard drive is one of the most obvious places to spend it. You can buy a larger drive; you can buy an external drive for backups; or you can buy several drives, and store data with parity using software RAID level 5. (Parity is an easy-to-use automatic backup mechanism: your latest data is still accessible even if a drive dies. Three disks with parity can store as much data as two disks without parity.)
Make sure you have enough cables for your drives. The A8V can support four UATA drives (two per cable) and two SATA drives (one per cable). The SLK3800B case has room for eleven drives.
Non-recommended variant: tape drive. Extra disks are a much better choice than tapes for backups. Disks used to be substantially more expensive than tapes, but they're now less expensive per gigabyte than almost all tapes. The only exceptions (160GB Super DLT I tapes, about $0.25/gigabyte; 200GB LTO Ultrium 2 tapes, about $0.20/gigabyte) require tape drives that cost over $1000. Even if you have so much data that you don't mind the cost of a tape drive, investing in tapes is silly: tapes wear out much more quickly than disks (a heavy-duty tape is rated for, at best, writing a few million gigabytes, which is equivalent to only about two years of disk use), and the replacement cost of disks is dropping much more quickly than the replacement cost of tapes. Of course, disks are also much faster than tapes.
Non-recommended variant: video cards using Radeon 7000. ``X DRI,'' standard software for Linux and BSD providing a graphics speedup, has bugs on the Athlon 64 causing Radeon 7000 video cards to crash. MX 4000 cards don't seem to trigger this problem.
Opening the case. Unpack the computer case. Discard its plastic wrap. Put on an antistatic wrist strap, and attach it to ground (for example, to the screw on a typical light-switch plate).
Stand the case on its bottom (four rubber feet).
Unscrew the big screws on the back of the case:
Remove the side of the case by pulling the two side latches towards the front of the case and then away from the case:
Put the side down:
From inside the case,
remove the power cord,
the brown box,
and any other loose items (such as dessicants):
Locate the power supply near the top of the back of the case.
The case may have a piece of paper taped to the top of the power supply
and covering the back of the power supply,
as shown above.
To fix this problem, unscrew the power supply,
grab the power supply from the inside of the case,
pull the power supply a few centimeters into the case,
and pull on the paper gently until the tape comes loose:
Then push the power supply back into proper position and screw it back in.
Opening the DVD slot in the case.
The front of the case is attached in several ways.
It may be taped:
It has two small bottom hooks, released by pushing inwards on the sides of the front:
It also has two small top hooks, released by pushing down inside the case, and two middle plugs, released by pulling the front forward. Undo all of these attachments to remove the front cover:
The case, without its front, should have a DVD-drive-sized hole at the top. If it doesn't, bend metal plates as necessary to make room for a drive. Sometimes this requires wiggling a metal plate back and forth until it snaps off; watch out for sharp edges.
Swing the front cover open.
Pop the top 5.25'' drive cover out:
Opening the video-card slot in the case. Lay the case flat on its closed side. I will continue talking about the ``top'' and ``back'' of the case to mean the parts of the case that would be top and back if the case were in standing position.
The back of the case has several slots for expansion cards,
each slot covered by a plate.
Remove the plate in the second position from the top,
by pulling up with moderate force on both sides of the plate:
Inserting the motherboard standoffs.
Open the brown box to find a bag of screws and brass standoffs.
Take eight brass standoffs out of the bag:
Look for a brass standoff
already installed at the back of the case:
Screw eight additional standoffs into a 3x3 pattern of holes, with the second and third columns narrowly spaced, the second and third rows somewhat narrowly spaced, and the top-left standoff slightly to the right:
If additional standoffs are already installed in the correct locations, leave them in place, and put the extra standoffs back into the bag.
Exchanging face plates.
Unscrew the face plate from the case:
If the face plate is attached by pressure rather than screws, find a hammer and gently tap the face plate out of the case.
Open the motherboard box and find a replacement face plate:
Tap the replacement face plate into the case, with two holes at the top and three holes at the bottom:
The face plate has two tabs bent into the case; bend them further so that they are at 90 degrees to the plate:
Installing the RAM. Take the motherboard out of its box. Lay the motherboard on a solid non-metallic flat surface, such as a wooden table. Look at the pattern of silver-circled holes on the motherboard; those will eventually line up with the brass standoffs in the case. If any brass standoffs don't match the motherboard, unscrew the standoffs and move them to positions matching the motherboard.
There are two blue DIMM slots (and two black ones) on the motherboard:
Push apart the white DIMM holders on the ends of the blue DIMM slots:
Unpack a DIMM.
Compare the middle notch of the DIMM to the bar inside the DIMM slots
to figure out which way the DIMM should be inserted.
Lower the DIMM gently into one of the blue DIMM slots.
Once the DIMM is resting on top of the slot, aligned properly,
push the DIMM into the slot
until the white DIMM holders are lined up in their original positions.
Repeat with the other DIMM:
Pushing a DIMM into its slot will require moderate force straight down into the motherboard. If the DIMM doesn't move down, apply slightly more force to one end until that end moves, then apply slightly more force to the other end until that end moves, and repeat until the DIMM is inserted. Never push the DIMM sideways; it could break.
Installing the CPU.
Pull the CPU-socket locking lever slightly out, then up to vertical
(picture shown for an older motherboard with the same CPU connection):
Take the CPU out of its plastic container and off of the black foam, revealing an array of gold pins:
Put the CPU into the CPU socket, with the CPU triangle on top of the triangle marked on the motherboard, at the opposite corner from the lever:
No force is required here; when the CPU is aligned properly with the socket, it will drop gently into the socket.
Push the CPU-socket locking lever back to its original position:
Here's a picture with the standard-workstation motherboard:
Installing the CPU's heatsink.
Take the plastic cover off the heatsink.
Put the heatsink on top of the CPU,
with the gray square face down on top of the CPU,
and with the big black clip toward the center of the motherboard:
Make sure that the big black clip is pointing up, and push the silver hook onto the black tab below it:
Do the same with the silver hook on the other side. Make sure that both hooks are firmly below their tabs. Rotate the big black clip---it will push back at you somewhat---and hook it into place:
Attach the dangling plug into the three pins at the edge of the motherboard labelled ``CPU fan.'' Orient the plug so that its lips hook around the pins:
Removing the hard-drive cage.
Unscrew the 3.5'' drive cage from the case:
Push the drive-cage lever towards the screw
and take the drive out of the case:
Releasing the power cables.
Take rubber bands and twist-ties
off the power cables from the power supply:
One power cable leads to a 12x2 array of plugs, consisting of a 10x2 array attached to a 2x2 array by two tiny pieces of plastic:
Push on the pieces of plastic to separate the 10x2 array from the 2x2 array:
Installing the motherboard.
Push cables out of the way of the motherboard:
Put the motherboard gently into the case:
Slide the motherboard towards the edge of the case. The motherboard will fit snugly into the face plate, under the tabs that you bent earlier, and the brass standoffs will be visible through the holes:
Slight force is required to push the motherboard into its correct position; the face plate has small tabs that press back slightly.
One of the brass standoffs,
the one already installed with the SLK3800B,
has a ball fitting into the middle hole on the motherboard.
Screw eight small Phillips-head screws into
the remaining eight holes on the motherboard:
Plug the 10x2 power plug into the motherboard until it clicks,
and plug one of the 2x2 power plugs into the motherboard until it clicks:
Plug the power-supply fan connector
into the PWR FAN connector on the motherboard:
Plug the reset-switch, power-switch, and HDD-LED (also known as IDE-LED)
connectors into the motherboard, all labels facing upwards:
Plug the speaker and power-LED connectors into the motherboard,
all labels facing upwards:
Plug the USB cable into the motherboard:
Installing the video card.
Unwrap the video card:
Plug the video card into the motherboard:
Moderate force is required, as for the DIMMs.
Screw the video card to the case:
Installing the DVD drive. The DVD jumper is probably set to Slave. Pull the jumper out and push it back on Master.
Find two of the drive rails in the brown box,
and screw them onto the DVD drive,
flush with the bottom of the drive:
Slide the DVD drive into the case from the front
until the drive rails snap into place:
If a small 4-pin cable was shipped with the DVD drive, plug the cable into the DVD drive and the CD connector on the motherboard.
Plug the UATA cable into the blue connector on the motherboard:
Plug the other end of the cable into the DVD drive.
Plug a 4-pin power cable into the DVD drive:
Installing the case fans.
Connect a 4-pin power plug to the installed case fan:
Plug the extra case fan into the position at the front of the case exposed by the drive cage. Plug the 3-pin fan connector into the AUX FAN connector on the motherboard.
Installing the hard drive.
Slide the hard drive into one of the five positions in the 3.5'' drive cage:
Screw the hard drive into the drive cage:
Screw in the other side.
If you have a second hard drive, repeat with that drive,
preferably leaving space between the drives:
Slide the drive cage back into the case, and hook it into place. Plug a SATA cable into the hard drive and the motherboard. If you have a second hard drive, plug a SATA cable into the second hard drive and the motherboard.
Connect a flat power plug into the hard drive.
If you have a second hard drive,
connect a flat power plug into the second hard drive:
Turning on the computer. Starting now, be very careful not to touch anything inside the case. Power will be flowing into the computer in a moment; if you touch something inside the case, you can electrocute yourself!
Take off the antistatic wrist strap. Turn the case's rear power switch off (0). Plug power into the case. Turn the power switch on (1). Watch the CPU fan, and press the front power button on the case. If the CPU fan doesn't start spinning, turn power off immediately; you have a problem. If the computer doesn't beep within sixty seconds, turn power off; you have a problem. If the CPU fan starts spinning and the computer beeps, turn power off; you have a working computer.
Assembling final pieces. Slide the front of the case back on, around the DVD drive.
Slide the movable cylinder onto the cylinder fixed to the open side of the case, with the smaller side of the movable cylinder closer to the side. Put the side of the case back on.
Put the computer in its final location. Attach the keyboard, touchpad/trackball/mouse, monitor, and Ethernet cable.
