I'm planning a small-form-factor PC with a budget of around $2,500–$3,000 and would appreciate feedback before buying the parts. The current list is a Ryzen 7 7800X3D, Gigabyte B650I Aorus Ultra motherboard, 32GB of G.Skill Flare X5 memory, an ASUS RTX 5070, a 2TB Samsung 990 EVO SSD, a Lian Li A4-H2O case, and an MSI MAG 750W Gold power supply. I'm mainly looking for advice on compatibility, value, cooling, and whether this would be a strong gaming build. The budget currency hasn't been specified yet.

The A4-H2O is a very popular compact case and has good airflow for its size, but its open-style layout may not be what you want aesthetically. You could compare it with other compact cases that use more enclosed panels while still supporting a radiator and full-size graphics card. Just double-check GPU length, thickness, radiator clearance, and the power supply form factor before changing cases.
For gaming, the Radeon RX 9070 XT is worth considering instead of the RTX 5070 if pricing is similar. It generally offers stronger rasterized performance and more VRAM, which can help at high resolutions. The RTX 5070 may still be preferable if you specifically need NVIDIA features such as CUDA, certain video-encoding tools, or particular ray-tracing and upscaling features.
That makes sense. I’ll probably switch to the RX 9070 XT unless I need one of NVIDIA’s specific features.
The biggest thing to clarify is whether that budget is in CAD, AUD, or another currency, since the recommended parts and value can change quite a bit depending on local pricing. The components should otherwise make a capable system, assuming the exact GPU and power supply models fit the case and meet their connector requirements.

The A4-H2O seems a little too open to me. I’m looking for something more enclosed that still has good airflow and supports similar hardware.
