Intel Pentium II 350
This Pentium II 350 is fitted with Intels' boxed cooling fan solution. In it's day it was often referred to as a 'shroud' cooling.
The CPU was fitted on an Intel Seattle SE440BX motherboard with 64MB of RAM. Not an unusual combination, however, I think that 64MB was not enough for most people in it's day. Too much open applications, anti-virus, printer software, scanner software and other resident programs used up too much memory causing stability problems in Windows 98.
The Intel Seattle comes in two versions: SE440BX and SE440BX-2. The regular SE440BX version supports only up to a Pentium III 450. If you install a Pentium III 500 you'll get a message indicating that this CPU is not supported for this motherboard. This made upgrade possibilities somewhat limited.
