50$ motherboard is garbage pile. You really want solid-cap motherboard - Thats 70$
BluRay reader 40$. WHY????? DVD+-RW multi. Writer. 40$.
Case + PSU 40$. Case may cost even 10$. But PSU with 105c Jap Cap @ Silver or Gold costs 90$. Alone. Thats 100$
Ram 4GiB 40$. Too small. Also, you get 8GiB for 40$.
Wifi --- why? Its not notebook.
HDD 45$, 500GB. No - 2x1TiB - 60$x2 = 120$
Thats mid range good gaming PC, that will not break in first 3 years.
