Inspired by other Antec 3480 builds on this forum I decided to build my own single fan system. I have used the following parts:
Antec NSK-3480 case
Seasonix X-400 fanless power supply
Intel DH67BL motherboard
Intel Core i7 2600k processor
Thermalright HR-02 passive cpu cooler
WD Scorpio Blue 2.5 inch 500Gb hard disk
8Gb Kingston DDR3 memory
Kingston SSDNow V+100 128Gb SSD
I wanted to build a small system with minimal noise production. At first I looked at the Fractal Design Array R2 case but because I had my doubts about the PSU and CPU fans I chose the Antec 3480. The Antec is a well built case and has enough space for the Thermalright HR-02 passive cpu cooler. I also liked the fact that it has a separate compartment for the hard drives and the PSU. Because of the grill on the top of the case the passive Seasonic PSU can easily get rid of it's heat.
Currently I don't have a separate videocard installed but because I don't use my system for games I have not missed it yet because the Intel HD 3000 that is built in the Core i7 2600k processor is quite fast.
Cable management proved a bit more difficult that I had expected, but I am quite happy with the result. Most cables are tucked behind the front panel (I had to use some force to get it back in place
I removed the 3.5 inch bay and routed the motherboard cables through the opening. Because the Seasonic PSU is a bit longer than the standard Antec PSU I could not fit the motherboard cables through the opening on the side:
The Seasonic PSU and the hard drives. I shortened the sata power cable. The two 2.5 inch drives are in a converter bracket and while WD disk is inaudible, the SSD drive is of course completely silent.
I have not used any of the external bays since I have a card reader built in my monitor and I never used the DVD drive in my old system anyway:
