Nice case, and good advice. I have ordered a bracket for the SSD, and will mount it (with a 6 terabyte HDD) in the 3.5" cage (which conveniently mounts in the lower area (and is easy to remove). Today's technology is simply amazing.
I'm finding the MM01 is very well-engineered, so that much of the innards are conveniently located and organized. They also have openings through which cables (power and data) can be routed through spaces outside the inner structure, but inside the exterior walls, for good cable management. The removable motherboard tray is genius.
I did find that trying to mount a water-cooling system would have been difficult. The massive air cool system I'm using is much easier, much less expensive, and just as effective (if not more so) because of the two massive (180 mm) MM01 fans, plus my additional 120 mm rear supplemental fan.
It's been a long and somewhat tedious build, but I think it's going to be well worth it. My biggest complaint is that the MM01 manual is sparse and of limited value (although in several different languages) for a non-expert DIYer.
No worries on my PSU (a Corsair 1,200 w), which comes with many connections, and labeled cables. I remember when builders had connections / rails that were not labeled, and cables that you had to investigate to see what they were meant for. They should have used different language on the fan power cables (e.g., connect to PSU via molex).
My old DIY computer (SIlverStone TJ-07 WindTunnel, 600 w PSU, ASUS Rampage III Extreme, Core i7, two AMD Radeon 6800) is still better than most other computers I see around, but this new one is going to be awesome. I just hope the Optane memory card and Optane accelerator are all that they are advertised to be. My new ASUS Maximus X Hero would benefit from an expanded instructional manual.
Thanks for your input.
