Update!
Changed the hdd's, fans and done some cable management.
Inside:
Motherboard: AsRock P67 Pro
CPU: Intel i3-2120 with ThermalRight HR-01 + Scythe SY1225SL12LM-P
GPU: Gigabyte Radeon 7750 OC + AC Accelero S1 ver 2 + Scythe SY1225SL12LM-P
RAM: 4x4GB Corsair Vengeance 1600 mHz
PSU: Sapphire Fire PSU 625W + Scythe SY1225SL12LM-P
SSD: 120GB Intel 520
HDD: 2,5" Toshiba 500GB + SQD 2,5" foam mounted
Case: Fujitsu TX150 S2 server rack case + 2x Scythe SY1225SL12LM-P Fans
All fans are connected to M/B 3/4 Pin connectors, idling at 400 RPM, PSU fan idling at 600 RPM.



To do list: Acoustic foam inside the case, maybe some i7-3770T CPU? Also, I'm thinking about some ITX web PC mounted on the shelf behind the front fan.
Best regards
