Well, it's been a while. I have some things to say about the build.
1. Paying $95 for a B85 motherboard is kind of silly. For that much money, you might as well get a newer and better H97 motherboard, no need to worry about whether it'll support the CPU or require a BIOS update, as it is guaranteed to be compatible with the i7 4790S.
For future expansion you want PCI-E slots, not PCI which is outdated and wouldn't be fast enough for wifi or USB 3.1/type C. They don't even make those cards for that type of slot anymore. You'll need room for
four PCI-E slots as the GTX 960 will take up two slots and the two wifi and USB expansion cards will need a slot each for themselves. Alternatively, you could use a USB wifi adaptor instead of the PCI-E wifi card, but it wouldn't be as good.
There's this somewhat more expensive
MSI H97-G43 motherboard (~$108) that has 4 PCI-E slots so it will definitely accommodate all that you want to add in the future. It also has better future-looking support for M.2 and SATA Express which are nice bonuses, and according to the manual it has voltage options that you can try for undervolting the CPU for even more heat reduction.
If you don't mind stepping up to a larger motherboard and case, then you could get this cheaper
ASRock H97 (non M) Anniversary motherboard (~$85), it easily has all the slots you need and then some. Pair that with a cheap case like the
Bitfenix Comrade (~$35) and it'll come out cheaper than what you have now.
2. Still interested in cases with bottom mounted front ports? The other day when I was looking for a cheap mATX case, I came across this, the
Thermaltake Urban S1 ($49) which has USB and audio ports on the bottom of the case. It only comes with a single 80mm fan though, so unless you have a spare 120mm fan on hand, I'd recommend buying one to improve airflow since you were concerned about heat, although the components you chose are already low-heat.
3. I think you should skip the blu ray drive too.
You don't even need an optical drive to install Windows anymore.

Well, about $90 was saved.. you could spend it on a better CPU heatsink that runs cooler and quieter than the stock intel cooler, or a better power supply to better support future upgrades. That EVGA PSU doesn't even meet bronze rating, but reviews say it's OK. If anyone else has recommendations for cheap, silent, and effective 120mm fans, feel free to chime in. The Antec Tricool is only there because I remember it having a three speed switch and it being pretty decent.. about 6 years ago.
