Overview
So the other day I had a UPS of mine die. After taking it apart as I like to do
with everything I thought what could I turn this into? After several ideas had
passed I realized that I had come up with a real good one. I thought hey why
not make it a hidden storage server. The question now is where to hide such a
hideous creation. Well that part was the easy part. Plain sight. So after some
tinkering and a few experiments and some research I decided to go ahead with
it. The ultimate hidden rogue server.

The Server Camouflage (also
known as an UPS)
This is the UPS we will be modifying. We chose a UPS for several reasons. First
off is we need the housing to be large enough to hide our server in, but still
be totally inconspicuous. second we needed to have network cables coming out of
our housing and not have it look odd, if we used a toaster with a LAN cable for
instance it might look a little suspicious but a ups with a LAN surge
suppressor in it for instance, no problem! Finally we wanted it to be an object
in the vicinity of the computer that would be connecting to it, after all the
best hiding place is in plain sight. I recommend finding a broken UPS from your
local surplus or thrift store, although CompUSA often has them on sale for
about 35.00. Make sure to find one with the rj45 surge protector. |

The NSLU2
I love this thing, ok maybe not that far. But when I first started creating
scope for this project I looked at various embedded technologies, nano-itx,
sbc's and pc-104. I chose the NSLU2 since it is small and already has Linux
loaded. It is natively a very robust piece of hardware and has several
customized and extended Nix based platforms available for it. I turned mine
into a DNS server for instance as well as my file server core. |

The Switch/Router
Remember that RJ45 surge projector? This is going to connect the two RJ45 ports
to the inside. The NSLU2 is also going to be connected to this. Since we don't
have an expensive UPS the rj45 ports aren't for remote management. You can
choose to use a 4 port switch or a 4 port router. I prefer the router because
it provides another layer of obscurity and security on the LAN in case it was
ever "audited". |

Laptop Drive with USB2
Any USB enclosure drive should work as long as it fits inside your ups. This
one is a 40GB laptop drive. The USB cable is a little weird on this 2.5 inch
external drive model, but as I didn't have to provide the drive with extra
power it was ideal. The second USB connector is for the extra power when used
with low power devices.

The Misc Junk
Some of the things that used for the build out were: 12 gauge copper wire,
solder, hot glue and glue gun, electrical tape, adhesive laminating film.

Tools
that we used
( I.E. you may want to use as well )
One note on power tools: use them at your own risk. Be sure to read and
understand any and all documentation on the tools you use. No amount of
documentation can make up for experience, but there are many people with
serious eye injuries at the school of hard knocks. If you don't know what you
are doing, don't do it and find some one that can help.
Scissors
Soldering iron
Hot glue gun
