This should be a [Build Help] post. Following the guidelines for such posts might not seen that important to you but the people who are trying to help you it is critical. Just using a title and posting the PCPP isn't good enough imo. When you are throwing down roughly 650$ at a build the more information you can give the better off you will be.
The amount of time I put into my comment shouldn't be greatly more than the amount of time you put into your post (there are exceptions though).
Here are things I don't know about your build given its current state. We don't know exactly what your budget is (we can assume 650$), what games you will be playing or if you plan on doing other things with the build, what resolution/FPS you are hoping to achieve, what country you are from (we can assume USA), if color scheme is important (i.e having like black and white build), if you want the most bang for your buck, does size matter (we can assume you want a micro ATX), does loudness matter (looking for a quiet build), do you plan to upgrade in future (with a 400W PSU and a micro ATX board we can assume no), do you plan to overclock, when you are buying your parts, how much storage do you need (with just 120GB SSD we can assume not much but yet again you might be under estimating how much you actually need), having USB 3.0 headers or USB ports on case is this important (we can assume yes)...
Now as you can see I assumed a lot of things about your build. I might be right about some things while wrong about others. If you don't state your intentions people will assume and thus not provide the best build for your situation. Wastes your time and ours.
So with your current parts this is what I think of. Pairing a processor that can overclock with a board that can't overclock is a waste of money. Even more so you should be looking at a skylake processor/compatible motherboard because from what I have seen they are actually pretty reasonably priced specially if you plan not to overclock. Also, your processor and video card doesn't really make sense. Going with an i3 and your video card (750ti) would make more sense (but yet I don't know exactly what you will be doing with the build besides gaming, who knows you might be using a program that benefits off a better processor (or even games you plan might benefit from a beefier processor)). Even buying a CPU cooler for a processor that won't be used for overclocking is a waste of money (this is assuming the processor comes with a cooler).
For your motherboard I would recommend trying to pickup a board that is higher quality that also includes wireless adapter. Basically if you throw the 30$ to the board and try and get a wireless adapter you will be better off (there are exceptions like wireless adapter not being as great of quality so it isn't worth it or might be a cheaper wireless adapter with better quality and separate motherboard for less than motherboard+wireless adapter combo).
Memory is fine.
Storage again I would look at this again with current games taking up a lot of space buying only 120GB drive isn't something I would recommend (but yet again I don't know what games you will be playing/buying). OS alone from I believe takes roughly 50-60GB (haven't done an install for a bit so not 100% sure).
Video card, I personally prefer Nvidia over AMD for reasons I am not going to get into. However, I am not oblivious that AMD offers the better bang for your buck. Cards I would recommend looking at are R9 280, R9 280X, R9 290, and R9 380. They are usually priced well for how well they preform.
Case you have a mid tower paired with a micro ATX board. I personally wouldn't recommend this but you might prefer this. Mid towers are a lot more easier to build in than micro ATX cases, however, they provide more space than what you actually need thus taking up more space.
PSU I would look over (bang for your buck is low). I can't say much because I don't know if you plan on upgrading or if you plan on changing your video card or adding more items that take more power.
Wireless adapter, I think you could do better given how much the one you have costs.
Other notes I personally would recommend buying parts on sale. /r/buildapcsales. Give yourself a 1-2 week span when you decide to buy. Buy parts that are on sale. Ones that don't go on sale buy at the end of the two weeks. Also, you have a bunch of different retailers. Ones that don't include tax or shipping thus your build is misleading. It also includes MIR which I am not a fan of but others will disagree. I have had poor experiences with MIR but others have had great.
