The Thecus n8800Pro is a 2U, 8 drive, inexpensive storage array. It comes with a pretty GUI running what appears to be embedded Linux. Clearly I had to get a normal Linux distribution running on there!
A quick Google on installing Linux on other Thecus models suggests that they are standard x86 hardware and perfect to get Linux onto.
The first thing you’ll notice is that there’s no VGA port on the back of the device:

Not to matter, there is a header on the motherboard for VGA:

First things first, you need a VGA cable, some pliers and other cutting instruments:

Carefully remove the blue plastic case and as much metal as you can from the cable, you should end up with something looking like this:

Next, you’ll want to ease your new plug into the holes on the motherboard. Use paper to insulate any metal parts of your plug from unintentional contacts on the motherboard. You’ll need to use something to hold the plug in place, paper works well. You may need to wiggle the cable a little to get signal:

Once you’ve got the cable in place, a quick reboot of the Thecus will give you the option to press DEL to enter the Phoenix BIOS:

Now you’ll need to change the boot order to allow your device to boot from USB CD-ROM before the Hard Disk. I couldn’t get LAN(PXE) booting to work. Then you’ll be able to boot from a CD and install an operating system of your choice.
