Anyone willing to review my Mini-ITX build? Intended use is for AI processing and graphical rendering.

Hi! I'm looking to build a SFF PC that will allow me mobility while not sacrificing much in terms of high-end specs. Trying to balance future-proofing with functionality.

Intended use is primarily AI process work and graphical rendering. Some game play, but this is ultimately intended to be a creative workstation more than a gaming rig.

Max Budget = $4,500 (purchasing in the US)

Current build plans:

Component	Selection	Price
CPU	AMD Ryzen 9 7950X3D 4.2 GHz 16-Core Processor	$592.08
CPU Cooler	Corsair iCUE H100i RGB ELITE 59.1 CFM Liquid CPU Cooler	$119.99
Motherboard	Asus ROG STRIX B650E-I GAMING WIFI Mini ITX AM5 Motherboard	$311.99
Memory	Corsair Vengeance 96 GB (2 x 48 GB) DDR5-6000 CL30 Memory	$342.99
Storage	Samsung 990 Pro 4 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive	$319.99
Video Card	NVIDIA Founders Edition GeForce RTX 4090 24 GB Video Card	$1,600.00 (purchased)
Case	Lian Li A4-H20 X4 Mini ITX Desktop Case	$154.99
Power Supply	Cooler Master V850 SFX GOLD 850 W 80+ Gold Certified Fully Modular SFX Power Supply	$129.99
Operating System	Microsoft Windows 11 Home OEM - DVD 64-bit	$124.99

Liquid Cooler: Looking for any feedback on my build, including whether anyone might have a better Liquid Cooler for this case. The A4-H20 is tight on space so I'm trying to be mindful of the real estate it takes up, but don't want to scrimp too much and purchase an inferior cooler. I heard swapping out the default fans on the H100i with ARCTIC P12s improves performance, so I may aim to do that.

MOBO/RAM: I'm also a bit concerned that I may be shooting myself in the foot for future expansion by going mini-ITX. My initial build plans called for mid-ATX Tower with ATX mobo, but the overall footprint and volume of the build left me with a rig I would have trouble moving around or even storing in my tiny dedicated office space. Trade off of the mini-ITX is max memory on the new mobo falls from 128gig down to 96gig. I read the Asus mobo may also need its bios updated to even support the 96gig (2x 48gig) of RAM I wish to include here. Not sure if that is true or how difficult it'll be to get it to work. In addition to that, open slots are minimal for the ITX which means future expansion is unlikely. I'll be honest though, I'm not planning to expand much anytime soon considering the specs.

Power Supply: Not much in terms of options for the case. Current build is estimating ~771W, so I went with the 850W. Not sure if that is a mistake or not. My original ATX build was aiming for 1000W+, but also had a lot more fans, so wattage was nearly 100W higher. Side note: If anyone is looking toward a similar power supply and doens't care about color matching the rest of the rig, the Cooler Master V850 White is oddly priced at half the price the black colored one is. Same specs.

CPU: For chipset, I went with AMD in part because of the large L3 cache coupled with the higher core count (for an AMD). Seemed like a good trade-off to Intel when it comes to CPU heavy data stuffing that is often seen with AI generation. If someone has a different opinion on this though, please let me know.

-------

Beyond the build itself, I also wanted to ask people's perspective on the timing of the chipset purchase. With NPUs expected to become the norm for most new chipsets in 2024 and beyond, I'm worried I'm purchasing just ahead of the curve. This may be too speculative for others to have much opinion on, but it is in the back of my mind. I've yet to see any true consumer-grade CPUS hit the market with integrated NPUS in them though. It's all laptop, mobile, and higher-end commercial chipsets it seems.

Lots to digest, so if you made it this far, thank you! Hoping my build details and thoughts might stir up some helpful conversations. Thanks!
