<br><font size=2 face="sans-serif">Chris, I put together a school server
from parts at a local computer supply store for $530. This</font>
<br><font size=2 face="sans-serif">is for a project for OLPC Uruguay (
http://wiki.laptop.org/go/Educational_Blogger_Project )</font>
<br>
<br><font size=2 face="sans-serif">The full parts list is here:
http://wiki.laptop.org/go/User:Az990tony/edublog-beta-hw</font>
<br>
<br><font size=2 face="sans-serif">In addition to XS, I also have Fedora
7 and Debian 4 Etch installed in a multi-boot GRUB.</font>
<br><font size=2 face="sans-serif">The software installation: http://wiki.laptop.org/go/User:Az990tony/edublog-beta-hw</font>
<br>
<br><font size=2 face="sans-serif">The entire machine needs only a single
RJ45 Ethernet connection. I am able to access</font>
<br><font size=2 face="sans-serif">the system remotely from my Windows
PC using OpenSSH. I have created a customized</font>
<br><font size=2 face="sans-serif">SysRescCD that allows me to boot into
SSHD mode to perform the install and admin remotely.</font>
<br>
<br><font size=2 face="sans-serif">Currently, I have it set up as a RAID1
mirror between two 160GB drives, but I have two</font>
<br><font size=2 face="sans-serif">30GB un-raided partitions, for a total
space of 190GB. The implementation could easily</font>
<br><font size=2 face="sans-serif">accomodate larger or more drives to
have the 500GB Wad suggests.</font>
<br>
<br><font size=2 face="sans-serif">I need to figure out Moodle+PostgreSQL
this week, then I ship it off to its final destination.</font>
<br>
<br><font size=2 face="sans-serif">Thanks<br>
</font>
