Hi,
on first look, good :- ). Would work, but some advice nonetheless:
Forget the Quadro, if you're working in 3dsMax, or most mainstream applications today (even including most CADs like Autocad, Revit,etc...), there is almost null benefit in going with Quadro for its OpenGL specialized driver.
Quadro cards still have many other benefits but they don't apply to 3D work. If you're interested, they are double-float precision for precise scientific calculations, 14bit lut support for very precise color managed pipeline (usually Hollywood level VFX, or medicine field), and ECC buffered ram for small error corrections in scientific calculations and to enable working in large clusters (super-computers).
Therefore, go mainstream depending on your needs. If it's just 3dsMax + Corona, anything will do. Really, even low-end. GTX 960/970 are absolutely great. Go higher if you have some additional interest only such as real-time engines or gaming.
Go 32GB ram. You write you have some already, so make sure these are compatible (able to run on same clock and timings).
Corsair H75 is weak, rather poor choice for close-looped water coolers. Buy either proper CLC with 2x140mm setup ( Corsair H100i, NZXT Kraken,FractalDesign Kelvin 24, Alphacool NexXxoS,etc..) or just proper Air Big Tower like Noctua NH-D15.
I do suggest to swap Seagate for WesternDigital. This is all based on statistic for longevity by BlackBaze, which arguably puts them at higher use threshold than regular users, but it's still good benchmark for which are more reliable. Seagate ain't it.

Also, alas, don't go for 1TB when the price for 3TB is so cheap these days. 1TB is less than I use for textures. And you will want to fit textures, models and projects on it. 1TB is too little.
Your PSU is OK. It's not the best choice though, and rather unorthodox. I would suggest going for more reliable brands as Seasonic, Super-Flower, (top choices), Enermax, Corsair, Silverstone (just as good).
Additional advice: You might be budget-conscious, so in this case, ignore this advice, but I've been working with 256GB SSDs for long time, and it's sub-optimal. It's ok if you keep to 3dsMax and Photoshop and bunch of other stuff. The moment you had some video editing, real-time engines (Unreal4), managing 256GB becomes a hassle and you will be constantly shuffling files around. If you can spare additional budget, 500GB is the way to go.
