I wanted to build a cheap backup file server. Nothing too fancy, it
didn't need a high spec, and I wanted it to be quiet and relatively low
power, because it would be on 24/7. I purchased a cheap fanless mini-itx
board, hard disk, memory, PSU, and set to building it into an old wooden wine
box.
First
to go in was the mini-itx motherboard. Holes were cut for network cable
and for airflow. The thread on the 12V DC power socket was just about
wide enough to let me screw it tightly to fix it through the backing
board.
Two
strips of wood were glued to the back to allow air to circulate more
easily from the back side of the motherboard, and also to stop the
screws holding it in from popping out through to the outside.
Two
further strips were glued inside of the 'top' and 'bottom' of the box
(left and right in the above picture), which allowed me to place two
snugly fitting wooden props on top of them. The boot and data hard disks
rested on the props, which kept them away from the heat sink to prevent
any contact or electrical shorting, and permitted airflow.
More
airflow holes were drilled (and later enlarged) into the top of the box
allowed for a small chimney effect to draw cool air in and hot air out.
There
was always a noticable 'warm wood' smell emanating from the box
whenever it was switched on. I was of course concerned that it would
catch fire, but the box was never under any great load, and the
fragrance was actually quite nice. I ran some software called
'motherboard monitor' was was able to graph the cpu and system
temperatures thoughout the day. After a couple of days, the temperature
remained stable and acceptably low, so I didn't really worry about it.
A
big red comedy power switch replaced the cheap little grey square one
that came with the motherboard, and a four way USB hub in the shape of a
robot was blu-tacked to the top to allow for easy file transfer by USB
stick. The robot also has big blue glowing eyes which were useful to
show that the server was powered on. The actual power and hard disk
activity lights aren't even fixed permanently, and are just
unceremoniously poking through one of the airflow holes.
One spare install of Windows
XP later, and it worked great! I also included a
webcam, some software to take pictures and turn the webcam into a
security camera, and installed IIS to let me view the latest picture.
Port 80 was forwarded from my home router, and hey presto, remote
webcam monitoring!
With no fans, and barely audible
hard disk activity, this was an ideal server to have in the living room,
connected via ethernet cable to my home router. Thankfully it never did
catch fire, and in the five or so years it was running, it was powered
on 24/7. A great first 'maker' project!
