Every single part fits perfectly.
Notes:
Yes, the XLR swivels about -20-degrees counter-clockwise from vertical. At first I disapproved. I would prefer vertical, but frankly don't care much now.
Slightly loosen all or some screws before fastening the top screws, then tighten all. Otherwise top screws might not fit perfectly and risk of stripping thread.
I'd prefer about 10mm less clearance between the two vertical binding posts.
Overall, chassis above expectations.
Included rubber feet nice surprise, big, soft, but protrude about 5mm outside chassis side panels. Trung suggested and I agree: attach inside with double sided tape.
Prefer the SR included free IEC over Parts Express. SR jacks about +20% greater tension.
Nice fastener quality, black anodizing above average.
Awesome, unexpected threaded all fastener holes. My fingers so big my guitar neck +1/8" wider than average...can barely hold a 3mm nut. No nuts required (well, you know what I mean, this is a family forum).
