Hi everyone. I recently inherited the above system. I've made a few modest mods to get it up to snuff for a bedroom HTPC. I want to upgrade the processor to a dual core which goes for about $30. Through extensive web research I understand that I need a copper heatsink for the pentium d chip. It seems like the heatsink I need is the Y1851 copper heatsink(?) I just want to confirm if this is the one I need for the SFF. I see some vendors listing it for the USFF version and some for the SFF. Also, it seems no one sells it with the shroud/assembly. Can anyone help in this regard. I will prob end building at htpc from the ground up eventually but I wanted something to play with in the meantime. Thanks
