Noctua Build Plan

I am planning for a full Noctua (edition) build, as follows:

- CPU: Ryzen 9 9950X3D
- GPU: ASUS RTX 5080 OC Noctua Edition
- MB: ASUS ROG Crosshair Hero X870E
- AIO: Noctua NL-LC1-42
- RAM: Kingston Fury Beast 2x32GB 6000MHz
- PSU: Seasonic Prime TW1600 Noctua Edition
- Case: Antec Flux Pro Noctua Edition
- SSD: Samsung 990 Pro M.2 NVMe 2280 2TB (x2)

Purpose: Hybrid machine for 1. running sim workloads and autonomous robotics model inference (training happens on a computing cluster, not on this machine), and 2. Occasional High-end gaming.

One SSD gets ubuntu, the other gets windows.

Questions:

1. In theory the AIO should fit in the Antex Flux Pro as per specifications. But anyone have experience testing this?
2. Not sure about the Samsung SSDs. Any SSDs that are better in slot in terms of performance (r/w speed) but similar price range?
3. General thoughts on the parts list and suggestions for changes? Assume wiggle room in the budget but not to the extent of “just get a 5090”
4. Any good-to-knows when working specifically with the set of components? (E.g. fan placement, air flow, cable management, PSU wiring, etc) Any extra gadgets that are nice to have?
