I had a squatter get mylastname.com after my dad died. After a while I guess they noticed that I registered mylastname.net and orffered to sell me mylastname.com I didn’t respond and they let it expire. I should probably register it.
For network cables, FS.com. Their specialty is fiber optics and they have good transceivers and cables for really cheap prices and they also sell a tool to flash vendor info onto transceivers so if you have some picky proprietary box you can still use generic transceivers with it. Their copper products, DACs, regular cat6 patch cables, etc are good too. I haven’t tried their NICs or switches though.
I have a used 2016 super micro server. It was $600, has 2 18 core/36 thread cpus and 256 GB of DDR4 and 12 HDD hot swap trays. It also idles at 180 watts. Way over kill but I have cheap electricity and it’s nice being able to spin up a vm with just about any specs I could want. If I got some more normal cpus it would probably burn a good bit less power.
What you are looking for is a RAG and is one of the few legitimately useful implementations of LLMs outside the wall of hype.
