INFO: Greg's Custom Built Mini-ITX

Editor's note: I've made any reference to money that was spent on the
project in yellow.
I'm not sure why, but I did. 8-)
Intro:
"Greg, can you build Hagar a computer?” I said, “Sure, what
you want in it?” “You just build it and we will pay you whatever it cost you.”
Wow, that might be something that you don’t want to say to me. :) So first off
this project has limited desk space. Secondly, this computer was built to be
cost effective, so I will throw in the prices for you. Mini-ITX ($120.00)
to the rescue, and I also wanted to build a mini system. I was then thinking to
myself “What can I put it in?” This led me to Hobby Lobby, my local craft store.
I began to look for a suitable “box” that would house my system. To aid in the
female look of the box I brought along my fiancé Kristi. I found just the right
one and got it okayed by the boss. It was regularly $25.00, but I got it for half
price ($12.00). I must say that some of my methods may seem somewhat
unorthodox, but I assure you that the strength and structure of the final
install is sound.

Let's do it!:
First, I stuck everything inside the box and tried to see how
I would mount it. I first decided that I wanted the DVD drive ($40.00)
to eject straight up, but after Kristi reminded me how CDs can fall inside, I
realized I needed to change that. I knew that I was going to put a “lid” inside
the box to cover all the computer components, so Kristi suggested I set it on
top of the lid. What would I do without her help? Besides having CDs stuck in
the DVD drive, I would be wearing dirty clothes and be malnourished. LOL. Now
that I had the general design down, I moved on to cutting out the holes for the Mobo connecters.
Before I begin marking where to cut I need to know just where
to position the template. I want some ventilation in this thing so I drilled holes
in the bottom to be the air intake. This also allows me to see how thick the
bottom wood is. After digging through some boxes I found the metal back cover
plate thing. I covered the back in the general area where I was going to be
cutting with scotch tape ($.75). I know that most
people would probably use masking tape, and I suppose there is nothing wrong
with that. I just prefer to see my working surface while I cut it. I did a
little measuring and traced the connecters onto the tape. Time for a little
cutting.

I’m sure you all know how to use a Dremel and a jigsaw so I
will save you the time. I did a little modding to the power supply unit (PSU -
$30.00) to get it ready. Everything that protrudes out of the back of the PSU is
going to add time and work, so I decided to save myself a little of both. This
PSU had an on/off switch as well as the voltage switch that were in the way. I
must say here that I take no responsibility for what you do. I recommend not
opening a PSU. It is dangerous and can seriously harm you. Having said that, I
opened my PSU. I cut the wires going to the on/off switch and spliced them
together. Bye bye switch. I then took out the screws for the voltage selector
and wrapped it in electrical tape. After I shoved the voltage switch back
inside, I closed the PSU back up. I next made a template of my PSU. I used a
cereal box ($2.50 man this stuff ain't cheap)
just like I always do. If I were you, I would save this template, because full
size PSU’s have a pretty standardized size and shape. I then used the template
to cut the box in the same manner as with the Mobo connecters. Now, how to hold
down the accessories?

This may look ghetto to you, but it will never be seen and it
does a tremendous job! To secure the floppy drive ($35.00),
hard drive (My old HD $30.00), and power supply I used
little bungee cords (4 for $1.79). I took screw
eyes (20 for $.89) and attached them on either side of the object. I then
fastened the bungee to one side and hooked it to the other side. The power
supply required two bungee cords going from side to side as well as top to
bottom. The floppy drive set some distance from the bottom of the box so I made a
bracket of sorts out of a Halloween candy dish ($.79).
The bracket screwed (tiny screws $1.00) into the box,
and the floppy drive sat on top if it.

bottom? |
The motherboard required further support, so I decided to
build a bracket. I went to the local hardware store and picked up a shelf
bracket (less than $2.00). The bracket is about 12”
long and is straight and flat. I am living in some apartments now, I had to move
away from home for a job, so I don’t have access to all the tools I used to.
Anyway, while I was at the hardware store I went to their tool corral where they keep
their vices. I stuck my bracket into a vice and bent it to my desired length
(borrowing their tools, free :)). When I got home I trimmed it, then used the Mobo as a template to tell me where to drill my screw holes. I don’t have a tap
and die set here, so I drilled the holes too large, and used epoxy to keep the Mobo screws
in. Once I was done with that I dry fitted it.

When I was ready to make the lid, I reached for some masking
tape ($.50) and a marker. I wrapped the top of the
box to protect it from the marker. I then held the pegboard ($3.00
- $4.00) on the top while Kristi traced the shape onto it. The wall
thickness on the box is ¼” so at all of the corners I put a dot a quarter inch
in. I then traced between the dots and cut the lid out. After dry fitting it I
marked where the floppy drive would sit. I went back to the jig saw and cut that out.
Kristi then sprayed down the cover with adhesive ($2.00)
and wrapped it (wrapping material $5.00 a yard,
half yard was plenty). I drilled a hole and mounted the knob ($.50). The screw for the knob was too long so I
cut a piece of my Bic pen ($.20) to fill in the
gap. Have a look below at the before and after… Nice!

Moving on, I sprayed ($1.00) the
bezel of the DVD drive black and wrapped that as well. I test fitted the drive
on the lid and noticed that the top of the door was hitting the top corners of
the drive. I took out the file on my Leatherman and rounded them off. I then
touched up the freshly filed corners with some paint.

At this point I soldered the wires to my new switch ($2.00),
drilled a hole for it, and mounted it to the box. I then began to mount
everything else inside. I had to remove the mounting bracket from the modem,
because it was in the way. I once again cut a piece of my Bic pen to use in
between the modem and the bottom of the box. I ran a bolt (10 for
$1.50) through the modem ($10.00),
through the Bic, and out the bottom of the box. Everything else went in and was
strapped together.

I filled in any divots with wood putty ($1.50)
and purchased a stain marker ($2.00) from the hardware
store to cover my efforts. I also used the stain marker on the inside of all of
my cuts. It really cleaned up the holes nicely.
