Inspecting the page, I can see that the specifications are placed in a div with the ID pcraSpecs:
<div id="pcraSpecs">
<script type="text/javascript">...</script>
<TABLE cellpadding="0" cellspacing="0" class="specification">
<TR>
<TD colspan="2" class="title">Model</TD>
</TR>
<TR>
<TD class="name">Brand</TD>
<TD class="desc"><script type="text/javascript">document.write(neg_specification_newline('Intel'));</script></TD>
</TR>
<TR>
<TD class="name">Processors Type</TD>
<TD class="desc"><script type="text/javascript">document.write(neg_specification_newline('Desktop'));</script></TD>
</TR>
...
</TABLE>
</div>
desc is the class of the table cells.
What you want to do is to extract the contents of this table.
soup.find(id="pcraSpecs").findAll("td") should get you started.
