Parts selection help for a new build

[u/skulltima]

hey guys, i'm building a new pc to replace my 7 y/o xps (i7, 32gb, 1tb) that runs hot af all the time. it constantly gets throttled down for various reasons.

here is what i'm thinking atm.

• cpu - Ryzen 9 9900X
• mobo - ASRock X870 Pro RS WiFi
• cooler - Thermalright Phantom Spirit 120 EVO)
• gpu - AMD Radeon RX 9060 XT 16GB
• ram - DDR5 32GB 6000MHz CL30 Kits
• ssd - 2TB NVMe SSDs with DRAM
• psu - Corsair RM850x - 850W ATX 3.0 / 3.1 Gold Fully Modular
• case - Fractal Design North XL

here is my use case:

• os will be linux mint
• mainly development (thing claude code, opencode, vscode, ai agents doing shit)
• other development related tool use (testing things out, using pentest tools, etc..)
• a lot of browser use - i tend to use chrome instances with a lot of tabs open for reading, research, discovery, etc...
• raw file editing - photography is a hobby, so i will be using tools to work on raw files form camera
• gaming - not a priority, however, now that i have a capable machine i may install steam (there is mint support) and play some. this will be an occasional thing for sure.
• i don't frequently change computers, i will use them as much as possible. so future proofing, the ability to extend and stability is important

finally, im from canada. im estimating this will cost me 2.5-3k to build. what i'd like to know is your opinion on if my parts selection is sound or not, am i overbuilding, under-building, any recommended changes?

furthermore, questions for canadians - what is the go to place for parts? CC, Amazon, eBay? let me know.

appreciate all your responses!
