====== Non-NUC Projects ======
Most of my Non-NUC projects involve having a second wired LAN interface.

You can also find my [[Monero CPU Miner]] on this site, which I am now using for [[https://foldingathome.org/|F@H]].

====== Work-From-Home (WFH) Firewall ======
A work-from-home environment needs to be reliable and secure. Something less expensive than a [[https://www.netgate.com/products/appliances/|netgate]] or [[https://protectli.com/products/|Protectli]] box with built-in WiFi. Given the recent Ubiquiti compromise, I'm not using their USG until further notice.
  * Secure and stable - [[https://en.wikipedia.org/wiki/PfSense|pfSense]] is a reputable firewall
  * Use my cellular LTE data as a second/backup WAN with a built-in wireless adapter - [[https://en.wikipedia.org/wiki/PfSense|pfSense]] again does this seamlessly
  * Two gigabit interfaces for LAN and WAN so I don't have to use a managed switch and trunking

The ZOTAC mini PC model [[https://www.zotac.com/us/product/mini_pcs/zbox-ci325-nano|ZBOX-CI325NANO]] was used.
  * Two gigabit wired interfaces (LAN and WAN)
  * Integrated wireless (dual band AC 3165, 3165NGW, 801.11ac)
  * Older CPU - Intel Celeron N3160 (quad-core 1.6GHz, up to 2.24GHz) 4 cores 4 threads
  * 2.5" SATA drive and two (2) DDR3L-1600 SO-DIMM RAM slots (16GB MAX)
  * Has a fan

Setup
  * WAN interface to cable modem
  * LAN interface to network switch
  * WAN2 wireless interface to Jetpack LTE data modem
  * WAN_GROUP uses WAN and WAN2 for internet access, failing over on packet loss or high latency
  * Ubiquiti Unifi wireless access points and CloudKey

====== freePBX ======
While I can use a NUC configure and trunked interface to run a VoIP system, I wanted two interfaces: VoIP network and DMZ. The [[https://en.wikipedia.org/wiki/FreePBX|FreePBX]] platform is perfect for my needs.

The [[http://www.qotom.hk/product/46-en.html|Qotom Mini PC Q220S-S02]] came configured as I wanted:
  * Intel Core i5 Processor, Dual core 1.7 GHz
  * 8GB RAM
  * 128GB SSD
  * Dual LAN
  * Fan ((Really annoying variable fan, not engineered like a NUC)), not suitable for desktop use
  * Compares favorably to performance of [[https://www.freepbx.org/appliances/|freePBX appliances]]
  * Does not have space to install two drives as RAID 1

====== Mac Mini Model A1347 ======
This is change of pace from refurbishing NUCs.

  * https://support.apple.com/en-us/111931
  * Apple support shows Catalina as being the latest compatible OS for this model; no further updates are available
  * 21 Monterrey was also mentioned
  * Probably has 1TB HD  running at 5400 RPM (very slow, no Fusion drive)
    * Option to change to SSD or add an adapter and NVMe

Notes:
  * This Mac must be compatible with the macOS that you're installing. If it isn't, it might start up to a circle with a line through it.
  * Mac must be able to connect to the internet; bootable installer doesn't download macOS, but it does need an internet connection to get firmware and other information for this Mac model
