The new PC

• Intel Core2Quad Q9550 4x2,88GHz at 12MB L1 Cache and 75W
  The CPU is one of the rather middle range parts for it is the still fastest and most accurate one that still is able to take 71°C and only needs 75Watt power in full load. Qualifying it for a fanless heatsink solution. Read a nice comparison here: Test of Intel Core 2 Quad CPUs
  


• Gigabyte GA-EP35C-DS3R
  Being the seemingly only Mainboard that supoerts ECC ram with that stepping as well as being power saving sensitive and passively cooled this was the first choice for th basis of the pc. Take a look at the manufacturers website Gigabyte GA-EP35C-DS3R
  


• DDR3 4GB
  Memory was a necessary part to be 4GB as well as ECC enabled, fast ram. So the choice for price fell to this one, CL9 PC3-10667 with 1333MHz clocking.


• Hitachi Ultrastar 1TB and OCZ Solid State Drive 32GB
  Those are the base for the software. The OS and essential drivers and programs will go to the SSD drive, so that or normal operation, mail, net, office and so on, no rotatig hard disk is needed... and thusfor no nose generated at all Also making a rather fast basedrive with 143MB/s read and 93MB/s write.

• ASUS EN9600gt silent/htdi PCI2 2.0
  Good performance, yet with no active coling that creates noise... This one is simply 0dB as it is passively cooled and still yealds a huge game and graphic performance Take a look here Review of the passively colled GPU


• Thermaltake Sonic Tower Rev2
  Wanting a real compleately silent PC, sure I need a passively cooled CPU heatsink. This one was the best and most efficient found in many reviews. Looks interesting Well.. have a look for yourself Test on "Ich bin leise"
