COMPARE PRICE, MEMORY, AND VIDEO WORK
Start with the video model you want to run. More GPU memory lets you use a bigger model. More GPUs let you make more videos at the same time.
Prices include the computer and Lacksan setup. Shipping and tax are calculated at checkout. A quote is needed when you add more GPUs or other parts.
| Best for | HP system | Price | What it gives you | Good choice when |
|---|---|---|---|---|
| Small NVIDIA computer | Z2 Mini G1i | $3,269–$4,399 | 8–20 GB of NVIDIA GPU memory. | You want a small computer for learning and short test videos. |
| Small computer with more memory | Z2 Mini G1a | Ask for a quote | Up to 96 GB for Radeon graphics from one 128 GB memory pool. | You need more memory in a small box and can use AMD tools. |
| One main video job | Z2 Tower G1i | From $5,699 | 24 GB in the listed build. A 96 GB build needs a quote. | One person makes one video at a time. |
| Two video jobs | Z4 G6i | From $21,648 | 32 GB in the listed build. It can hold two GPUs. | Two people or two video jobs need to run at once. |
| Three video jobs | Z6 G5 | From $39,631 | One 96 GB GPU in the listed build. It can hold three GPUs. | You need room to add more video jobs. |
| Four video jobs | Z8 Fury G6i | $91,061 | Four 96 GB GPUs in the listed build. | Four big video jobs need to run at once. |
| Very large AI work | ZGX Fury | Call for price | 252 GB of fast GPU memory and up to 496 GB of CPU memory. | A model is too large for a normal Windows computer. |
Simple answer: start with 24 GB for local video with people. Pick 32 GB for more room. Pick 96 GB for much bigger models. Add more GPUs when you need to make more videos at the same time.
These numbers come from the video tests linked below.
| Test | RTX 5090 Lightning Z | RTX 5090 | RTX PRO 6000 |
|---|---|---|---|
| Wan 2.2 5B in ComfyUI | 109 sec | 113 sec | 120 sec |
The 5090 won this small test. The RTX PRO 6000 has 96 GB of memory, so it can run bigger models. It will not win every speed test.

| Version | Wan model file | LTX model file | Human-video result |
|---|---|---|---|
| Full / BF16 | 27 GB | 46 GB | The full model used for the test. |
| Q8 | About 14 GB | 23 GB | Best small file in the test. Q8 stayed closer to the full model than FP8. |
| Q4 | 9 GB | 14 GB | Budget choice. The person scene showed softer faces and identity drift; Wan LPIPS 0.34. |
| Q2 | 5 GB | 8.3 GB | Avoid for ads with people; Wan person-scene LPIPS rose to 0.54. |
What LPIPS means: a lower number is closer to the full model. In the glass test, Q8 got 0.07 and FP8 got 0.19. In the LTX sound test, Q4 had 46.9 error and Q5 had 9.9 error.

BEST FOR: A SMALL NVIDIA COMPUTER
This is the small NVIDIA choice. It works well with ComfyUI. The GPU matters: some builds have 8 GB and some have up to 20 GB.

| Lacksan price | $3,269–$4,399 |
| Video use | Small NVIDIA computer for local video |
| Most it can hold | Up to RTX 4000 SFF Ada · 20 GB of GPU memory |
| What to pick | Choose 16–20 GB for Q4 test videos. Pick a tower with 24 GB or more for better videos of people. |
| YouTube lesson | Q4 shrinks Wan to 9 GB, but the person test showed softer faces and identity drift. |
Memory size · this is not a speed test
BEST FOR: MORE MEMORY IN A SMALL BOX
This AMD computer can hold a large model in a small box. Its shared memory is not the same as NVIDIA GPU memory. A model may fit, but it may not run fast.

|---|---|
| Price | Ask for a quote |
| Graphics | Radeon 8060S · shared memory |
| Memory | Up to 128 GB shared · up to 96 GB can be used for graphics |
| Best for | Big models, small size, and tests that use less power |
| Video limit | It has more memory, but fewer ComfyUI video tools work with AMD than NVIDIA |
BEST FOR: ONE BIG VIDEO JOB
