From my local price list. Converted to US$.
CPU & Mobo: i5-4440 & MSI B85M-G43 @ $268
A micro-ATX mobo which offers more features compared to an ITX mobo.
Ram: Crucial 1600mhz 2x4GB @ $72
ODD: Samsung DVD RW @ $19
HDD: WD Blue 1TB @ $58
SSD: Crucial M500 120GB @ $92
Another good alternative is Plextor M6S 128GB.
Case: Fractal Design Define Mini @ $104
More of a mid-tower design. Sleek and has sound proof material. As it is a mid-tower design, it has more room to accommodate longer graphic card in the future and able to fix standard PSU size instead of SFX.
PSU: FSP Aurum S 500W @ $72
Total about $685.
You can look for these parts online in places like Newegg or Amazon, and there are some websites who assemble the machine at a fee then ship it to you. Best to get it all in one place, you often need to have a minimum order value before they'll offer free shipping. If you're going the self assemble route, take extreme care; constantly ground yourself, work somewhere far away from a carpet and air conditioning if you can avoid it, only remove components from their anti static bags immediately before installing, do not allow components to sustain any sort of impact, do not touch any contacts of any sort.
Always ask if unsure.
Cheerio,
