At $150+ I would just buy an old small form factor dell / hp from ebay and have a whole machine.
Sure, it's hulking, obsolete, and very loud beast, but it's hard to beat the price to performance ratio there... just make sure you don't put anything super valuable on it because HP's old proliant firmware likely has a ton of unpatched critical vulnerabilities (and you'd need an HP support plan to download patches even if they exist)
I picked up a HP 705 G4 mini on backmarket for $80 shipped the other day to run Home Assistant and some other small local containers. 500gb ram, Ryzen 5 2400GE, 8gb ddr4 w/ a valid windows license.
Sure it's not as small or silent, but there's no way to beat the prices of these few-years old enterprise mini-pc's
