The RTX market is particularly irritating right now, even second-hard 4090s are still going for MSRP if you can find them at all.

Most of the recommendations for this budget AI system are on point - the only thing I'd recommend is more RAM. 32GB is not a lot - particularly if you start to load larger models through formats such as GGUF and want to take advantage of system ram to split the layers at the cost of inference speed. I'd recommend at least 2 x 32GB or even 4 x 32GB if you can swing it budget-wise.

Author mentioned using Claude for recommendations, but another great resource for building machines is PC Part Picker. They'll even show warnings if you try pairing incompatible parts or try to use a PSU that won't supply the minimum recommended power.

I thought those 4090’s were weird. You pay more for them than the brand new 5090. And then there’s AMD, which everyone loves to hate, but has similar GPU’s that cost 1/4th of what a similar Nvidia GPU costs.
