SSD only in my PC - Is it possible?

Thanks.
What do you think about configuration:
CPU -> i5 4690k
GPU -> R9 270
MoBo -> MSI H97-Gaming-3
HDD -> western digital 1tb
RAM -> hyperx fury 16gb
Power Pack-> 600w
Total -> about ~€800
It’s not a budget computer, so do you recommend me i5 4460 + R7 265 -> so I will spend ~€680?
