My only other suggestion beyond the GPU is the ram. 4800 is about as low as you can go with DDR5 and the kit you picked is CL40, so really aiming low with that. 6000ish is generally the sweet spot for the Ryzen CPUs and CAS latency closer to 30 is desirable. This Teamgroup kit is better all around and only a couple dollars difference or you could save a few bucks and go with the Patriot Viper kit which is pretty much the same thing. I'm not big on Patriot's styling usually but they generally have very good prices for similar specs.

Edit: Almost forgot you added you're on Linux now. I'm not well versed on the subject, but generally AMD GPUs are preferred for better stability. May want to look into that before you decide on one.

Double replying. I ended up throwing a new build together. This, as-is, is just over your 1k CAD price point, with the potential to go lower depending on if you can get some of these parts locally. Some are listed as out of stock but the site shows some in stock at some stores. My train of thought with the CPU change is while the 9600X only has a slight performance advantage, more importantly it has a 40% reduction in TDP which will be easier for your H60 to keep cool and prevent any thermal throttling.

Edit: I reconfigured the build a little, which may be better depending on what you play with it. Went back to the 7600X with this one and swapped the 9060XT up to a 16GB model. Lots of people complain about 8GB not being enough these days which really depends on what you're playing. Want to play all the latest and greatest or heavily mod your games with high(er) res textures? Having that extra 8GB is necessary. Focused on older games or don't mind not maxing out your settings? The 8GB would probably suffice (especially while running in a PCIE 5 slot). So that will give you some options to consider. I personally like my eye candy and while I don't spend a lot of time with new games using state of the art graphics, I do quite like my modded games and my 9070XT regularly sees 12-16GB+ of VRAM usage.

I’ll look into the themal paste as well since that is an easy thing to replace.

Just wanted to mention, because it's often overlooked, check the thermal paste on your GPU as well. My wife's system was crashing constantly in games and it was driving us crazy trying to figure out why. Then, I pulled the GPU cooler and found the thermal paste was more "powder" than "paste". Cleaned the old paste off, applied new paste, and the system ran like a dream for another year or so before she upgraded the GPU.

Fair, perhaps I didn’t look at prices recently either.
