Finally ended up getting a digital camera (Canon A70) for a combination xmas/bday/graduation gift. Had it one day now, time to put it to use.

So, here's some pics of what I am currently using as my backup server. I have daily backups scheduled for my three other systems for the middle of the day while I'm away at work. This currently only has a 60gb Cuda IV, but that's adequate (barely) for now. Need to get some video files off to CD for more storage space.

The hard disk stays around 37-40^C, depending on ambient. It sits on the floor, so it does have a better chance at cooler air. MBM won't find any temp sensor for the CPU, which I'm not surprised about. Being only a P3-566, its not putting out much heat (relatively), even while Folding 24/7. Since the one fan is an exhaust, CPU load and temp has no effect on hard disk temperature. The system usually only has power (an external brick, buried in wires under the desk, wasn't going to dig it out for pics) and Cat5 hooked up.


Specs:

HP e-Vectra system
P3-566
128mb memory
60gb Seagate Barracuda IV
Panaflo L1A

The System
Image

Image

Hard Disk cover, slides off for access to the HD carrier
Image

Image

Back side of the system, I cut out the slot as an intake for airflow over the hard disk
Image

The case slides forward off the chassis
Image

The HD carrier lifts out
Image

The HD spaced down with doubled motherboard standoffs, was originally mounted flush, which worked fine for the old 8gb 5400rpm drive, but the Cuda was seeing 60^C for temps so I spaced it down
Image

Image

Modified top vent, originally had the puny little vent holes pictured on the side vent
Image

Image

Image


Side of the case, cut out the internal grill for better airflow, this goes across the bottom of the HD
Image

Front of the chassis, I taped over the front slot where there was an option to mount a laptop CD drive, spacing the HD down takes the space where the CD would have been
Image

Image

Fan mount, L1A hardwired to 5v as an exhaust fan, original fan has a variable voltage feed that starts at ~4.5v, ramping up with CPU temp. Unfortunately it wasn't usually enough to start the L1A, and then was too much when it warmed up.

Image

Overhead view, the right side had a double layer of metal below the HD that I cut out to drop the HD and get better ventilation
