For your purposes, you could probably get by with just OCS, and if the standard plug-in does not provide enough information, you can easily add your own (perl) code.

#!/usr/local/bin/perl

use strict;
use warnings;
use Parse::DMIDecode;

my $decoder = Parse::DMIDecode->new(
              dmidecode  => "/usr/sbin/dmidecode",
              nowarnings => 1,
            );
$decoder->probe;

my @keywords = $decoder->keywords;

foreach my $keyword (@keywords) {
    printf("%s => %s\n",
            $keyword,
            $decoder->keyword($keyword)
        );
}
