Well, I have just built a new 'quiet' rig based on a P180b with a P5B Deluxe mobo... but not because of any prevalent consensus in these forums.
However, it was what brought me to SPCR - I had set my heart on a P180 from the start, but I wanted to make sure I was making the right decisions, so I trawled the web looking for reviews - and consequently I came across the good 3-part review of the P180 on here. And hence, I 've now joined the forums...
It's understandable that the P180 has higher profile here given Mike's involvement in it, but I find it's universally recommended with a handful of others across the geek communities. Likewise, the other components.
I'm a long-time member of the Bit-tech
community which has it's roots in the modding and gaming communities, and of course, these days noise is as big an issue as performance and cooling. If you were to ask for recommendations there ( as I did) you would find these same components would be in the top 3 in each category. Why? Because the cream naturally floats to the top. You'd get the same recommendations at Hexus and Bleeding Edge, and everywhere else too.
Sometimes a given community might have a local favourite, but this is natural. One guy buys Component X and recommends it to 3 others, 2 of which buy it, and recommend it to 3 more others each. In no time at all, everybody who is anybody has Component X. The proviso is that Component X must be good in order to prosper.
And I will certainly be recommending the P180b and the P5B Deluxe to anyone who is prepared to listen.
