Ultimate Homelab, Unifi Home Network and A/V Rack Tutorial

Building a half rack for in-house use is a task geared likely on or more rather specific use cases I will cover several but this should not be taken as an exhaustive list of all them. The hardware you select will also vary widely based on many factors such as your noise preferences, heat tolerance in the half rack site location, electric rate, and availability. I present my selections and reasons as a study in my application which can serve as a reference for you. I show assembly, installing hardware, cable management and light construction in the accompanying video which has a decent amount of hands on. In the interest of expanding the coverage on this topic I will not revisit those topics, so it is advised to treat these as two separate but related pieces of content.

There will be a follow-up that is more in depth on the configuration and showing off in a future video. These are specifically related to my setup, but likely have a lot of overlap with any common setup for an all-in-one rack setup. Yes I have a mini datacenter in the garage also but 90% of homelab or A/V rack setups will be all-in-one like this. 

• Today we are going to be building out the house nerve center (my smart home’s central hub), which includes the following use cases:
  • Audio/Video Home Theater Receiver
  • Low-noise Homelab and NAS
  • Battery-backup powered home network
  • Desktop virtualization hosted off whatever homelab server we get in here
  • Surveillance System
  • An Interactive House Assistant

• Likely Use Cases
  • Home Media Center
    • Jellyfin for ripped disks
    • XBOX for Discs
    • Music Player
    • Photo Management
    • Some place to run my old school bluray drive to rip disks ideally
  • IoT Hub
    • Home Assistant
    • Multi-room Audio
    • Voice Assistant
    • Logging
    • Smart Controls
    • Lighting controls
  • Virtualization Host
    • 2-4 end user terminal areas
    • Windows or Linux Virtualization
  • Home Network
    • 1GbE, 10GbE, PoE, WiFi 5/6/7 for “normie net” which is our Home Network
    • WiFi support for calling is a must
    • Hardwired things

• Constraints
  • Inhospitable attic
    • Low pitch
    • R60 insulation
    • Super hot
    • Insulation triggered asthma
  • Stucco walls on house
    • Bad for all RF
    • Cannot drill big holes w/o damage potential
    • Longer range WiFi works MUCH better as a result
  • Shamrock shaped house
    • This plus stucco =  very poor coverage from any central AP
  • Pretty big yard
    • Direct burial CAT cable
    • Need to place several access points to achieve entire yard coverage
  • Infrequent but extreme weather conditions
    • Frequent Lightning-to-pole strikes
    • Infrequent Ice
    • Torrential Rains
    • Animals eating COAX
    • Cable ISP is highly impacted all the above

• Goals
  • Home Theater
    • 7.1.4 Atmos for Living Room
    • 4k 60p HDR for Living Room
    • Integrated Harmony Remote Control
    • Integrated Locally Hosted Voice Control
    • Multi-room Audio for Spotify/YT Music
    • Access to Security and Home Assistant Feed
    • Enable A/V – Networking Rack to move out of closet cabled
    • Zone2 Sm Guest TV

  • IoT Hub
    • HA Integrated with local LLM
    • Voice controlled
    • Voice assistant
    • Lighting control
    • Surveillance Integrated
    • Door Logger
    • Motion Logger
  • Home Network
    • Maximized battery runtime capabilities
      • Test, ensure you have setup power-down with NUT
    • Failover WAN
      • You can do this on the cheap with a cell phone tether plan, and a mini wifi 802.11x capable router that can bridge connections. TP link makes these in their AR-150 lineup. Of course you can use also a full uplink to a secondary ISP.
    • Label, map and document all drops
    • Test and verify all connections
      • Look for 10/100 blinking orange lights on any cables.
      • Check the connection speed reported if you go unifi, its presented on each switch devices details panel.
    • Ensure 550MHz cable on all 10Gbe drops
      • Do not use 350MHz cable connected to 550MHz cable for 10Gbe connections. Ideally, just get new cables for the entire infrastructure and do it all at once and buy matched A or B patch cables at 550MHz at the same time.
    • Migrate to Unifi network for all 1-10gbe and PoE for my normy-net. This is not the same as the garage datacenter net.
    • Install centrally a U7 wall pro and several ceiling based AC-AP-PROs
    • Create an ingress point for the network to be hardwired to outside.

• Outcomes Achieved
  • Highly serviceable all-in-one rack that can easily support our entire houses tech needs
  • Failover capable
  • Amazing indoor wireless coverage achieved
  • Atmos 7.1.4 Achieved
  • Unifi gear is great for our low performance demand household network
  • UnRAID for our NAS off the Lincstation
  • Zone2 Setup for Video/HDMI audio achieved.

• Lessons Learned
  • Heat is not magic, its based off watts and a Threadripper makes a lot of those. Putting that in a closet will lead to heat gain and fans gone wild.
  • Spectrum techs need to be watched if they are in the house ever again. One left the door to the A/V room open to outside and about a million mosquitos came in.
  • I need better crimping tool for CAT6 with the nice pull thing, my old school one is not fun.
  • Surface mounting the CAT6 punch plate for the wall drop is a much better way to go about this vs keystone wall plate mounting. It does look slightly janky however while keystones look amazing.
  • I failed to factor in gaming! Serious oversight.
  • Redundant circuits could be a stretch goal if you have 2 UPS’s but it is also useless as most of the non-fixed, non-enterprise gear does not have 2 PSUs.
  • UnRAID is still the easiest and most fun way to create a small home setup for basic uses fast.
  • I bought some older and unusable unifi gear early on in this. It is a fairly dense ecosystem with a lot of constraints of its own.

Assembly Order (Bottom to top)

Heavy stuff goes rack‑bottom for tip over safety. If you can air gap hot equipment against cool stuff that is ideal.

Mine went in like this:

1. UPS + battery modules at base
2. Threadripper 4U case just above
3. Shield and Cable Modem
4. Networking Gear
5. Lincstation
6. HA Controllers
7. Xbox disc player
8. Marantz at the top

I like it, I like it a lot!

Cabling & AP Placement

Pulled all my CAT6 (550MHz) cables and fiber and HDMIs before starting this project. Run wires is before install and setup rack. The placement of wires is likely to be behind your rack and access is easy now. Every AP is home‑run PoE. No mesh-mode. If you’re in stucco + weird floor plan hell like me, this matters.

Central House area: U7 Wall Pro
Outer rooms: ceiling‑mount UAP‑AC‑Pros
Yard: direct‑burial CAT run to outdoor AP location to ???? (prolly a vid at some point)

Wire your spans before you wire your Half Rack internals. Again hand drawn plans are valid also, but take notes and possibly document with photos on your phone. That came in VERY handy for me with the Marantz!

Extended running in poweroff scenarios

If there’s an outage, the AVR and Xbox can die instantly for all I care. The Cable modem, UXG Pro, PoE switches, and Cloud Key stay alive until internet fails or UPS runtime is 3 mins to empty.

I’ve got the UPS scripted via NUT so Group 3 (non‑critical) shuts down first, then Group 2 (servers) after a grace period. Keeps Wi‑Fi up for phones/laptops the longest. I have had 2 occasions to run extended off battery for the network and it performs well for this.
