The 14th gen didn’t only have problems with Linux and I still don’t trust Intel when they say they “fixed” the CPUs disassembling themselves. Given the money involved I’d definitely advise against 13th and 14th gen Intel in any case, just not worth the potential headache down the road. Either go with older Intel or AMD.
Imo if you’re going to be the only one who would use the instance it is not worth it. Instead look for an instance that lines up with your personal interests (maybe check out the db0 instance).
Content federation basically works on a subscription model so you will only see content from other instances if someonen your instance went out of their way to subscribe to it. Smaller instances suffer under this as they might not even see popular communities from other instances.
