90K+ Intel core ultra 7 265k vs 9 285k for Video Editing. Critic my build

I doubt you would get a case with 4 HDD Bays in the price range, the least you can get is a case with 2 SSD and 2 HDD trays.
I picked the CM Masterbox 520 SE but then having using CM's since decades. So gave it thought and I needed a front glass too, went ahead and bought the Montech Sky two. Its a pretty sturdy case and comes with reversible fans.

I would suggest to bump up the main boot drive to a bare minimum 1TB. https://www.amazon.in/Crucial-Plus-PCIe-NAND-5000MB/dp/B0B25NXWC7/ Cheaper than your price tracker and double the storage.

And instead of a 9k mechanical drive get a 2TB PCI Gen 3 NVME SSD. https://www.amazon.in/Crucial-PCIe-NAND-NVMe-3500MB/dp/B0B25MJ1YT/

Pick a motherboard with 3 NVME and install another NVME 2-4TB when you need more space in the future. Buying a mechanical hard drive for a editing rig is not advisable in 2024. Mechanical drives only make sense for a NAS not the main workstation. In my opinion of-course. Once editing for a project is done keep a high quality export for future projects when you need it. Delete the HQ, raw or prores footage once done. I had a project which had like 400Gb footage which was changed to a 40 min video. I am not keeping the 2.5hours of RAW footage just eating my HDD space.

3TB should be plenty as a main work drive. Hard disk prices will only come down in the future so you can easily expand more in the future. I can scrub Black magic camera 4k BRAW footage in Davinci resolve on my laptop so your beast of a machine should be no issue.

And I whole heartedly recommend Davinci resolve. Learning a NLE which is away from Adobe jail and has so much support is great. I have the Studio Version but even the free version is so powerful. Adobe tax is horrendous. Even AHEM adobe premiere does not make sense. Again in my opinion.

Cooler Master 4000D Airflow is a decent case, 2 ssd and 2 hdd mounts, front type c and under 7k
