My thoughts are:
- Your selected Motherboard does not have digital audio I/O. What are your requirements for audio playback and downstream equipment? I would never recommend using the built-in analog outputs. Did I read that you plan on using the 960s audio output? Maybe that would work, I'm not really sure.
- Absolutely, positively, do not skimp on RAM. Go with at least 32GB and don't let anyone tell you it's overkill because it's not. Moreover, at $130 for 32GB, it's hardly the place to be saving money. Myself... I would even consider going with 64GB and setting up a huge RAMDisk for processing large files, but whatever you go with you need to buy it all up-front and do not plan to expand later. Mixing and matching DIMM modules, even if the same Brand, is frequently problematic. You want every DIMM to be the same make / model and ideally from the same manufacturing lot.
- For Case and PSU, I really like Corsair products, but that's just me. I have no anecdotal experience with the Be Quiet! brand and choosing a case is entirely individual preference.
- For CPU fan and heatsink, I would strongly recommend going with Noctua. They are the bee's knees of cooling devices and their included thermal paste is among the best.
- SSD - I would personally avoid a TLC drive, but they are definitely a large share of today's market. Google that specific Samsung EVO model... the 840 was plagued by firmware issues the last 1-2 years. Buying an SSD is all about researching reported issues specific to each model.
The WD RED series is good for large capacity storage, I have a 3TB model.
Lot's of good advice so far, but with this I would respectfully disagree and consider it a huge no-no. RED drives are intended for NAS use, not desktop use, and there is a slew of negative reports associated with the Red line including (but not limited to) faster failure rates. Get a caviar black and never look back.
