You have cheaped out further than I would like as it is. I would want quad channel DDR4 You could have used DDR3 instead with another board.
I would want a faster, better SSD
I would want a higher-performance PSU.
if you want to save, forget about faster ssd, you won't notice the difference really unless you benchmark or something.
i have an old sata2 ssd, and a fairly new sata3 ssd, one is faster but on a blind test i would not be able to tell
