The success upgrade and maintenance for my existing gaming rig finally allow me to complete building DIY home NAS. The previous Intel Pentium I got from eBay very dirt cheap is basically too slow and realizes it was single core version. Since the new ASROCK motherboard I brought able to support up to Intel Core 2 Quad, I decided to replace with Q9400. At the moment I am testing which OS to run my file storages so it is preferable to have ready hardware to meet some of the open source requirements. Anyway, these are the hardware specifications for my complete custom NAS or file server builds. Many of them are existing stocks so I actually save quite a lot all this years. If you have read my previous posts for Aerocool DS Cube and ASROCK G41S-GC R2.0. The remaining purchases are new power supply unit (PSU) and pen drive.
