I built something similar last week, but my budget was little bit tighter. if you are interested i will post some pics later.
MOBO: MSI Z97 Gaming 3
HDD: Western Digital Blue 1TB (64MB)
SSD: Kingston HyperX 3K SSD 120GB
RAM: Crucial Ballistix Sport 8GB DDR3-1600 CL9 kit
CPU: INTEL Core i5-4690K
CPU custom cooler: Gelid Solutions Tranquillo
GPU: MSI Nvidia GeForce GTX 960
PSU: EVGA 600B
CASE: Nanoxia Deep Silence 3
MONITOR: HP Z24i
I know both SSD and monitor are not the best choices but i got them for 150€(ssd+monitor) so i am not complaining.
I would rather have modular PSU with better efficiency but EVGA is fine and has enough power for future uprgrade.
Regarding headset i will go for Hyperx Cloud Gaming.
