Are you opposed to the cloud? You could get an even beefier machine on the spot market for under a buck an hour while you’re using it, then turn it down when you’re not.
Do you have a link to this unicorn cloud machine ? I'm very interested for something faster than a bare-metal 32-cores threadripper with 128Gb of ram and a 2TB SSD (NVME I guess) for less than $1 an hour.
An M6a on AWS has 128 GB of RAM and 32 cores and goes for around $0.60 on the spot market. If you need local SSD and you’re willing to go ARM, an m6gd has a similar spot price and nearly 2 TB of NVME local storage. I’m sure other cloud providers have similar offerings.
I agree with the root comment though that you may want to look at building in a cloud provider using spot instances. You’d have to invest in automation to spin up and tear down machines and manage build artifacts, but it might be more cost effective and operationally simpler than investing in your own hardware.
I haven't benchmarked these instance types, but in the past on the common instance types, t2 from memory, an AWS v-core was similar to core on a very low end cpu.
