I'm honestly really horribly confused about the direction this is headed.
Why are you opting for the bottom of bottom-tier cases on the market to house some of the best components on the market? Case design and manufacturing has come a long way since 2004. ATX mid-towers like the NZXT S340, Phanteks P400, Phanteks Enthoo Pro M, Fractal Design's Define S and C now dominate the market, and small form factor mini-itx cases like the Node 202/804 are rising in popularity. Easily-accessibly exotic cooling is coming with cases like the NSG-S0.
Why do you need a wired adapter when there is a vastly superior one on the motherboard?
Why do you need a sound card when there is a superior one on the motherboard?
No SSD? At least get SSHD/fusion drives.
You shouldn't need an extra tube of thermal paste unless you plan on remounting your cooler a bajillion times. The H7 comes with a 1gram tube of CP7, which is surprisingly good stuff. And 1 gram will last you at least 10-15 cooler re-mounts. I still have a few drops left after 15~ish cooler mounts. Used it on a bunch of water blocks recently. Thermal grizzly kryonaut is still the best in my book, if you want to have a look. Pricey though.
Why a Z270 motherboard without a Kaby Lake CPU? Do you already own the motherboard and/or the CPU? A Z170 board is, in all likelihood, cheaper than a Z270 board (price premium for having the newest) with no added benefits other than aesthetics, which matters nil if you're putting it in that atrocious excuse of a case.
No one uses fan controllers anymore. Your motherboard has at least 6 fan headers, and unless you're running custom water cooling, I doubt you'll need more than half of those headers with the use of fan splitters for easier fan speed management. PWM is the norm, 3-pin voltage-controlled headers are dying off.
I would recommend the dual-band TP-Link WDN4800 PCIe wifi card over that thing. Way faster, more stable, and more range.
I wouldn't buy that mouse. Have a look at the Ninox Venator and Nixeus Revel. Or the Fnatic Flick G1 and Gigabyte XM300 if you don't like symmetrical mice. For productivity, I saw the 1st gen logitech mx master on sale on Amaz(ing)on for like $35. Basically, unless it has a Pixart 3310/3360/variant of either, I wouldn't go near them for gaming.
In this day and age, there is really no point in building an i7 rig unless it's purely for gaming at high resolutions and refresh rates. I'd look into the Ryzen 5 1600 for general gaming, and the Ryzen 7 1700 for heavier-duty work. For either CPU, a B350 motherboard is under 100 bucks, and will have a longer feature list than is fathomable by the typical power user. It'll also shave at least a hundred bucks off the overall cost for equivalent performance.
With that monitor, at 1080p and maxes out its adjustable refresh rate at 76hz, a GTX 1060 6GB will be able to max out most games. If you need overkill, a GTX1070. With the current GPU pricing, the only reasonably-priced GPU's on the Nvidia side are the 1050/1050ti, 1080ti, and Kepler/older architectures.
These are only some of the issues I have with that list. However, nothing on your list is actually incompatible, it just doesn't make much sense. It's probably a lot to stomach, but I'd hate to see anyone trash that much money for the sake of antiquated notions of power computing. Unless there is something that I'm unaware of here.
