Re: [K12OSN] Server Planning



I left out that a server of this type can be built for about $6k. As I
have one of the top system build groups down the street from me
(www.monarchcomputers.com) I use their stuff often.

This puts the cost per seat at about $350 ($6k - server, 200 TC's at
$300 [NTAVO box, 15" LCD monitor, keyboard, mouse] plus power strips and
some network cables and all the software you can load!)

Dell Dimension 1100 package (with 17" CRT monitor, LCD extra) is $680
with MS XP Pro and a 90 trail anti-virus.
