Great design. I am building computers for years and I am happy that you pointed out that passive cooling is not an easy job for everyone. Especially finding the right mix of the motherboard, the location of the processor on the motherboard, the length of the heat pipes, the case and the TDP of the processor. As Streacom recommends a TDP of 65 W for permanent use and I want to use the server for video, also - I selected the Streacom ST-FC5S EVO with the CD slot and the i7 3770T with 45 W TDP. I want to be on the safe side. Better to stay in the middle of a computer equipment’s specification than using the equipment on the edge. The Haswell generation will provide a similar processor with a better graphic unit. Unfortunately there is no drastic reduction of power consumption. Therefore the specification of that Ivy Bridge processor is fine with me.
Next week I will get my processor. Hopefully.
