Double Checking My Dream Build: Will Everything Work Smoothly?

Hey folks! I finally went ahead and ordered all the parts for my ultimate gaming setup after tons of research and some great help from AI. I'm super excited but wanted to share the full list of components and ask if there are any last-minute concerns or potential issues I should be aware of. I'm having it built by a professional, but I want to make sure everything fits and runs perfectly together.

My main goal with this build is for 4K ultra gaming, VR experiences, and to ensure it's future-proof. I usually play as a support character and want a machine that's reliable, cool, and operates quietly, while also being capable of handling both intense FPS games and cinematic AAA titles.

Here's what I've got:

- **CPU:** AMD Ryzen 9 9950X3D (16-Core, dream machine)
- **CPU Cooler:** ARCTIC Liquid Freezer III Pro 360mm AIO
- **Motherboard:** MSI MAG X870 TOMAHAWK WIFI (ATX, AM5)
- **RAM:** Corsair Vengeance 64GB (2x32GB) DDR5-6000 CL30
- **GPU:** ASUS TUF RTX 5090 32GB
- **Storage:** Corsair MP700 PRO 2TB PCIe 5.0 NVMe
- **PSU:** NZXT C1500W 80+ Platinum (Fully Modular)
- **Case:** Lian Li O11 Dynamic EVO XL (Full Tower)
- **Case Fans:** 6x Noctua NF-A12x25 PWM chromax.black.swap
- **Fan Hub:** ARCTIC Case Fan Hub
- **OS:** Windows 11 Pro OEM DVD (just in case, I'll bring a USB too)
- **Monitor:** Alienware AW3225QF 32" 4K QD-OLED (240Hz, 0.03ms)
- **Anti-Sag Bracket:** Lian Li GB-001
- **Builder:** Local shop (East Coast Computers)

Now, here are my specific questions:
1. Will all these components fit in the Lian Li EVO XL case?
2. Can I comfortably top-mount the AIO cooler with the RAM and GPU installed?
3. Does my motherboard support all the fans and the cooling setup with the hub?
4. Are there any compatibility or BIOS issues I might need to prepare for?
5. Am I missing anything small like extra cables or thermal paste (beyond what's included)?
