Step 1: Prepare to hack
For those that would like to run Linux on the stock hardware with little in the way of extra features, http://berklix.com/scanjet/ has some great info, and even a complete FreeBSD installer for the device. This is where I got my start on hacking this device.
My main motivation for the mini-itx upgrade was that the power supply exploded a capacitor and damaged too much of the PSU to be easily repairable, and I also had a EPIA 800 board sitting around waiting for a home.
tools and parts you'll need:
- soldering iron
- #1 and #2 phillips screw drivers
- needle nose pliers
- wire snips and stripper
- IDE hard disk of your choice
- 50-pin SCSI card (I used an older Tekram)
- PCI right angle riser, "A" side, 5Volt. I used a 1.03 height from risercardshop.com, only US site I could find with that height.
- mini-itx, or smaller, mainboard. I used an EPIA 800, low enough heat and more than enough power.
- 1U rackmount power supply (135 Watt seem to work)
- 24 Volt 1.7 amp power supply (I used a 1.9 amp, little more doesn't hurt, also be sure to read the summary at the end)
- sacraficial AT/X PSU and molex to 3 wire fans plugs for extra plugs and wires or willingness to cut up an expensive PSU to splice wires
Most of this stuff I had laying around (I'm a bit of a packrat) so this project only cost me about $30 out of pocket.
