Homelab Server Rack Build

The Problem

The hobby had grown. What started as one server under a desk had become three machines, two switches, a UPS, countless cables, and a growing collection of “temporary” solutions that were becoming permanent.

The desk was gone. The floor was covered. Cable management was a distant dream.

I needed containment. I needed structure. I needed a rack.

What We’re Building

A proper homelab rack housing:

Dell R620 1U server — The heavy lifter
Mikrotik CRS305 — 10G switching
Ubiquiti US-24 — PoE for access points
Cat6 patch panel — Finally, cable management
PDU — Power distribution
UPS — Battery backup for the essentials
Fiber ONT — ISP connection

The Hardware

Rack Components

Component	Model	Price (Approx)
Rack	StarTech 25U	$300
PDU	StarTech 15A	$80
Patch Panel	Cat6 24-port	$40
Cable Manager	1U horizontal	$20
Rack Rails	Dell compatible	$50
UPS	CyberPower 1500VA	$180
Server	Dell R620 (used)	$300

Total: ~$970

Server Specs: Dell R620

Component	Specs
CPU	Dual Xeon E5-2660 (16 cores / 32 threads)
RAM	128GB DDR3 ECC
Storage	8x 2.5” bays
NIC	Dual 10G SFP+
PSU	Dual 750W (redundant)

Yes, it’s old. No, I don’t care. Used enterprise gear is the homelab way: cheap, powerful, and built like tanks.

The Build Process

Step 1: Rack Assembly

The StarTech rack came flat-packed. Assembly was straightforward — four posts, casters, sides, top. Took about an hour with basic tools.

Pro tip: Don’t fully tighten bolts until everything’s aligned. Square frames make happy admins.

Step 2: Planning the Layout

Before mounting anything, I planned the layout:

Top:
  1U - Cable manager
  1U - Patch panel
  1U - Mikrotik CRS305
  1U - Ubiquiti US-24
  1U - Blank panel

Middle:
  1U - Dell R620
  2U - Open for future expansion

Bottom:
  2U - CyberPower UPS
  1U - Blank panel
  1U - PDU (rear-mounted)

Heavy things go low. Heat-generating things have spacing. Patch panel and switches are at eye level for easy access.

Step 3: Cable Management

This is where the magic happens. Every cable:

Labeled at both ends
Measured to length (no excess loop)
Secured with velcro (not zip ties — reusable beats permanent)

The patch panel connects to wall ports throughout the house. Each port labeled: “Living Room”, “Office”, “Bedroom”, etc.

Step 4: Power Distribution

The PDU provides 8 outlets, but I’m only using:

Dell R620 (primary)
Dell R620 (secondary)
Mikrotik switch
Ubiquiti switch
Future expansion x4

The UPS protects the critical infrastructure: switches and the server’s secondary PSU. If power fails, the server stays on long enough for a graceful shutdown.

Step 5: Network Topology

ISP Fiber ONT
      │
      ▼
Mikrotik CRS305 (10G backbone)

      ├── Dell R620 (10G SFP+)
      │
      ▼
Ubiquiti US-24 (1G distribution)
      │
      ├── Access Points (PoE)
      ├── NAS (1G)
      └── Rest of the house

The Mikrotik handles 10G traffic between the server and NAS. The Ubiquiti handles everything else with PoE for access points.

Performance

Network Performance

Test	Result
Server ↔ NAS (10G)	600-800 MB/s
Server ↔ Internet	1Gbps (ISP limited)
Client ↔ Server	115 MB/s (1G saturating)

Power Consumption

State	Draw
Idle	180W
Under load	280W
With AC	Adds 30W for cooling

For 24/7 operation, that’s ~$25/month in electricity. Cheap for what it provides.

What Runs Here

The R620 runs Proxmox with VMs for:

Plex — Media server (with GPU passthrough for transcoding)
Home Assistant — Smart home control
Docker host — Various containers
Pi-hole — Network ad blocking (redundant with main instance)
TrueNAS — NFS storage for the other VMs

The rack also houses the main NAS (separate build) and networking gear.

Lessons Learned

Enterprise Gear is LOUD

The R620 sounds like a jet turbine until you tweak fan curves. Default settings assume datacenter noise floors — your living room is not a datacenter. IPMI lets you adjust fan thresholds.

What I Learned

Measure depth before buying. The R620 is deep. Make sure your rack (and room) can accommodate full-depth servers. I had to rearrange furniture to make it fit.

Pro Tip

Plan for growth. I left 2U open. It’s already filled with a new NAS chassis. Leave room — homelabs have a way of expanding.

What I Learned

Label EVERYTHING. Future you will thank present you. Both ends of every cable. Every port. Every breaker. Trust me, six months from now you won’t remember what goes where.

Note

Battery backup is essential. Power blips happen more often than you’d think. A UPS prevents database corruption and angry family members when the WiFi goes out.

Future Upgrades

Sound dampening — A proper enclosure or dedicated room
Cooling — Better airflow management
More storage — The 2.5” bays in the R620 are limiting
10G everywhere — Slowly migrating clients to 10G

Conclusion

The rack transformed chaos into order. Everything has a place, cables are managed, and I can actually work on things without untangling wires first.

There’s something satisfying about walking past a rack of humming equipment in your own home. It’s the grown-up version of a fort. A very expensive, very loud, very useful fort.

If your homelab is creeping across the floor, invest in a rack. Your sanity (and your spouse) will thank you.
