<DIV><FONT face=Tahoma size=2>Hello,</FONT></DIV>
<DIV><FONT face=Tahoma size=2>It seems your platform is more suitable for a
cluster. Great, and when are the products available? And is there any software
support from you?</FONT></DIV>
<DIV><FONT face=Tahoma size=2>Regards,</FONT></DIV>

<DIV><FONT face=Tahoma size=2>Hello,</FONT></DIV>
<DIV><FONT face=Tahoma size=2>Is it too expensive for the
platform?</FONT></DIV>
<DIV><FONT face=Tahoma size=2>The easy solution is:</FONT></DIV>
<DIV><FONT face=Tahoma size=2>And X48 level motherboard with CF support,
about $150 </FONT></DIV>
<DIV><FONT face=Tahoma size=2>Q6600 Processor, about $170</FONT></DIV>
<DIV><FONT face=Tahoma size=2>Two 4870X2 $1,100</FONT></DIV>
<DIV><FONT face=Tahoma size=2>Two Seagate SATA Harddisk 500G for Raid1,
about $140</FONT></DIV>
<DIV><FONT face=Tahoma size=2>4*2G DDR2 RAM, about $150</FONT></DIV>
<DIV><FONT face=Tahoma size=2>PSU 1000W, about $200</FONT></DIV>
<DIV><FONT face=Tahoma size=2>A big box, about $100</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Tahoma size=2>That's all, in total, $2,010.</FONT></DIV>
