Holiday Gift Guide 2025: The Best PC Parts for the Local AI PC Builder
Local AI is shockingly capable, and a desktop PC can be a surprisingly powerful AI machine. While on the surface, building a gaming PC and AI PC are similar projects. But there are a lot of differences that make building an AI PC unique from just about any other type of PC build; you have to keep different priorities in mind.

A GPU With Lots of VRAM
The GPU is the most important component in any local AI PC; if you’re looking for a lynchpin of a gift, this is it.
When it comes to AI and GPUs, NVIDIA is often cited as leading the pack. While their CUDA ecosystem is still the best, most widely supported backbone for local AI apps — and anything else that uses GPU-based compute — AMD has recently entered the LLM GPU game with their Radeon AI Pro R9700.

The absolute floor is a GPU with 16GB of VRAM — don't go below this! Cards like the Gigabyte NVIDIA RTX 5080 or ASUS NVIDIA RTX 5070 Ti are fantastic options.
For more GPU memory, you're looking at higher-end models like the ASUS NVIDIA RTX 5090, which has a whopping 32GB of VRAM. The RTX 3090 Ti is also worth a look — it has 24GB of VRAM, and Micro Center has refurbished units that can help cut down on the price.
Of course, if you’re looking for the most VRAM and have the budget to spend, there’s always the NVIDIA RTX PRO 6000 with a massive 96GB of RAM.
A CPU That Won't Bottleneck the PC
While most local AI tasks use GPU inference, it's still important to have a fast CPU that won't bottleneck your PC, though some AI tasks use CPU inference, too. You might want to use Whisper, a CPU-bound inference model, to convert speech to text locally on your own PC. In this example, the faster your CPU, the better the model you can run — and the faster it can turn audio into text.
Photo: Jacob Bobo The AMD Ryzen 9 9900X CPU is an excellent choice starting choice. For heavy CPU inference tasks — even more extreme performance — you could step up to a Ryzen 9 9950X chip. The Intel Core Ultra 7 265K will also do the job with aplomb.
Remember, as with building a modern gaming PC, the GPU is the priority. You're better off saving some money on the CPU and putting that cash towards a higher-end GPU.
More RAM Than You Might Think
While you can get away with 16GB of system RAM on a gaming PC, 32GB of RAM is the minimum you'd want on a local AI PC. The more the person plans to do with the PC — running multiple big models, working with big documents, or running different types of models on both the CPU and GPU at — the more RAM matters.
Photo: Jacob Bobo To have room to spare, 64GB of RAM may be a better target. But don't overthink the RAM — faster RAM won't make much of a difference. The speed of the GPU's onboard memory is more important than the system RAM. Capacity is the most important, so you're better off with 64GB of DDR5-6000 RAM than 32GB of DDR5-7200 RAM. DDR5-6000 RAM is probably the sweet spot.
This G.Skill Flare X5 kit will give you 32GB of RAM and is optimized for the AMD chips we recommended above. If you're targeting 64GB for a higher-end build, this Corsair Vengeance kit will do the trick. Just be sure to buy one kit and not mix-and-match different RAM kits.
An SSD Ready for Big AI Models
A local AI PC will need an SSD that's capable of taking a lot of use. Anyone downloading models, fine-tuning them, and creating vector databases is going to be putting an SSD through heavy usage many consumer drives just aren't built for.
Look for a PCIe Gen4 SSD with a high TBW (total bytes written) rating, indicating it can take a lot of writes. Speed matters, but the kind of high-end SSDs we're talking about here will deliver both high speeds and serious durability.
Photo: Jacob Bobo Capacity matters a lot, too. AI models are huge, and they can take up disk space fast. A 2TB drive is workable, and I wouldn't get anything smaller. Naturally, a 4TB drive will give your lucky gift recipient a lot more head room than a 2TB drive.
Samsung SSDs are a great choice — the Samsung 990 Pro 2TB drive has a 1200 TBW rating and the 4TB version has a 2400 TBW rating.
A Power Supply to Power That GPU
Modern GPUs can use an incredible amount of power, so don't skimp on the PC's power supply. For an RTX 5090, you'll want at least 1000W of power — and maybe up to 1200W, if you went for a high-end, power-hungry CPU.
For an RTX 5080, you'll want at least 850W. For an RTX 5070 Ti, you'll want at least 750W. Check what your GPU and CPU require. If you're on the edge, get more wattage than you think you may need. You won't regret it.
Photo: Jacob Bobo Quality matters — not just wattage. An 80 Plus Gold PSU from a reputable brand will be all you really need. For many builds, an 850 watt power supply like this MSI MAG PSU will be a great fit. This Super Flower 1000 Watt PSU is a step up in wattage.
A Case with Great Airflow
If a desktop GPU is running LLMs all day, it's going to produce a lot of heat over a long period of time. So, think practical: Get a case with good cooling and airflow. You probably don't want it to be too compact, either; make sure it has enough room for a big GPU.
Photo: Jacob Bobo A case like the Fractal Design North XL would be beautiful — what better match for an AI PC than a case with natural wood elements? But case selection is such a personal decision that I think you should choose a case that fits your gift recipient — not just one based on a spec sheet.
Quiet Fans for Better Cooling
Since airflow is essential, be aware: There's a good chance the stock fans that came with your case aren't going to be enough. You'll want quiet fans that can provide high static pressure to ensure consistent airflow and keep your PC's components — especially the GPU — cool. Depending on your case and the fans it comes with, you may want to add a few extra case fans.
Photo: Jacob Bobo You could get swanky LED fans like the Lian Li Uni Fan, but the Arctic Cooling P12 will do the job, too, just without the lighting. Both are nice and quiet.
A Bundle to Get You Started
A bundle can be a great place to get started with building a local AI PC — you can get a motherboard and CPU at a discount, and even add some RAM and save some extra cash.
For example, the AMD Ryzen 9 9900X bundle is currently available with a motherboard for $449, while you can get the Intel Core Ultra 7 265K CPU with a motherboard for $349. Take those savings and put the cash toward what really matters: The GPU.
Or Maybe: A Prebuilt PC With the Right GPU
A prebuilt desktop PC can be a great local AI PC, too. Not everyone wants to build a PC, and prebuilt desktops are often available at a nice discount.
Keep the same principles in mind when choosing a prebuilt desktop PC: You want one with an NVIDIA GPU, and the GPU's VRAM matters a lot.
For example, this PowerSpec G758 gaming PC combines an NVIDIA GeForce RTX 5070 Ti GPU with 16GB of VRAM with a speedy AMD Ryzen 7 9800X3D processor, 32GB of DDR5 RAM, and a 2TB Samsung SSD. This hits all the minimum requirements for a surprisingly capable local AI PC without breaking the bank. For a bit more, you can get a similar G757 gaming PC with an RTX 5080 GPU.
This HP Omen 45L GT22 gaming PC gives you an RTX 5090 with 32GB of VRAM along with an Intel Core Ultra 9 processor and 64GB of system RAM for about the price of an RTX 5090 GPU by itself, making this a truly crazy deal if you have the budget for it.
Or Maybe: An AI Mini PC
'Tis the Season for Local AI
With local LLMs becoming more powerful than ever, it's a great holiday season to give the gift of local AI to someone who's interested in it. And the best part? The software is free. It's a gift the open-source AI community gave to us.
