Notes:
1) Not sure if APAC supports hyperthreading, the fastest i5, the i5 4690, is used instead. (The GUI and the legacy OS support........

)
2) The H87M Pro 4 comes with Intel LAN and RAID support.
3) The 840 Evo SSD is used to allow you to enjoy fast boot times and fast loading times and enabling you to open and save large files quickly.
4) Not sure how much HDD space do you need, do remember to upsize your HDD accordingly. The WD Red HDDs are used as they are designed for usage in NAS and RAID arrays.
5) The Asus PCE-N15 is good for up to 300Mbps of data transfer speeds. Can also consider the TP-Link WN781ND ($35) if you think the Asus adapter is too much for you. The WN781ND is good for up to 150Mbps of data transfer speeds.
