pure silicon computer (no moving parts)
For some environments, and applications, noise is an enemy. However, if a PC is to be used, how badly you wanted
the machine makes noise from fans and harddisks, while they are spinning generating mechanical noise. Air-flow also
can contribute significantly to the nose inside the PC.
So the option is to build Solid State computer, without moving parts. Here is how;
1) fan-less CPU+Motherboard. (indicative price on ebay Rs 40,000)
Via EPIA series embedded boards or JETWay boards
2) Memory
Any DDR series would work depending on the motherboard. This is anyway noiseless
3) Hard Disk
SSD comes into play. A 250GB drive would easily cost over USD 600 on ebay.
Alternatively, can use Memory Stack drives, CF-SATA drives etc. if a huge drive space is not critical.
4) Power Supply
There are many fanless PSU units out there. Bellow pictured unit is on ebay for US$ 175
WELCOME TO THE NOISELESS WORLD!
