If you want to stick to the DIY approach, I like FreePBX. I haven't tried it for several years, but I do keep updated about it via different Subreddits. I have been looking at some whitebox appliances for firewalls, but they would work for micro-servers/PBX pretty well. There's a dual gigabit, Intel Celeron, AES-NI, 8GB RAM, 120GB mSATA for $259 that would probably work especially well I would think.
Yealink phones are great, no arguments there.
Have you considered pre-built PBX? Grandstream has their UCM6202 for $220 on Amazon. It's a nice WebUI over an Asterisk backend in a pre-built appliance. I use this internally for our company, on-prem for clients, and in our data center as multi-tenant PBX for hosted clients.
I have used Axvoice and Voip.ms, and I'm using Flowroute personally. Our company uses SIPTRUNK.com internally and for client systems.
