First of all I wanted to thank SPCR for the great reviews and for this precious forum.
First post, first silent PC. Here's my experience.
I started with a Grandia GD05 as a base. I must say that I'm not completely satisfied by this case, mostly because the fans are constrained inside the chassis and it's almost impossible (at least for me) to completely remove vibrations. Apart from that I think it's a good small case.
The other components are:
CPU: i5 650 (for reduced power consumption)
CPU cooler: shuriken big with stock fan replaced by an akasa apache black
GPU: cyclone 460 768mb
PSU: seasonic 430w
Mobo: Gigabyte h55m-usb3
case fans: 120mm scythe s-flex (good from 600 to 900rpm)
HD: 500gb spinpoint f3
RAM: 4gb corsair ddr3 1600
I was not sure the shuriken big fit together with the cyclone, but luckly it worked out pretty well. It was a pain to lock it into the socket, though.
The cyclone cooler fit just by a millimeter into the case http://img6.imageshack.us/i/gpuw.jpg/
. I was worried about the GPU noise, but I'm completely satisfied by this little beast, in idle/standard-use is inaudible.
The akasa apache black is one of the best pwm fan I've ever had. I had to set the speed with voltage (not pwm) though because the mobo was not sending it at less than 1000rpm. All the other fans are at ~600rpm.
With all the fans spinning at max speed (~1200rpm) the CPU stays at 26°C (idle), at 600rpm I have it at 32°C (22-24° room temp).
Power consumption is at 60w idle, 180w load.
