A finished 10-inch mini rack homelab is a tidy tower about 16 inches tall that sits on a desk or a closet shelf: a small patch panel up top, a quiet 2.5GbE switch on a vented shelf, a mini PC on its own tray, a row of Raspberry Pi boards facing front, and a power strip feeding everything from one cord. This method uses the 8U DeskPi RackMate T1 as the frame and only parts whose makers list them for 10-inch racks. It is for anyone running a few Pis or mini PCs for Home Assistant, Pi-hole, Proxmox, or a small cluster who wants the cables and power bricks off the floor.

10-Inch vs 19-Inch Racks, in Plain Terms

A 10-inch rack is a half-width version of the 19-inch racks in offices and data centers. The number is the width of the front panel of anything that bolts in. Height is counted the same way in both: 1U is 1.75 inches, so the 8U T1 has 14 inches of mounting space. The difference is what fits. A 19-inch switch, patch panel, or shelf will not bolt into a 10-inch rack, and a 10-inch part will not fill a 19-inch rack without adapters.

Stay with 10-inch if your lab is a few small computers and one switch. Go 19-inch instead if you are terminating house Ethernet runs in a closet, need a 24-port panel, or plan to rack a full-size server. That build lives in Home Network Rack Kit: Patch Panel, Switch, and Shelf, and none of its parts carry over to this one.

What You Need

Every part below is listed by its maker for 10-inch racks, and the shelves are sized for the T1's 7.87-inch depth. Bring a Phillips screwdriver, a few cable ties or hook-and-loop straps, and the power supplies your Pis and mini PC already use.

The rack

The T1 arrives flat-packed with its assembly hardware. It weighs about 10.5 pounds empty and measures roughly 11 by 7.8 by 16 inches, so it fits on a desk corner or a closet shelf. The open front and perforated acrylic sides let you see and reach everything. The common buyer complaints are price (some call it overpriced near $150) and that it lacks extra cross supports, so do not stack heavy gear on its top panel.

Patch panel

A 0.5U, 12-port Cat6 pass-through panel. Each port is a coupler, so a short cable plugs in the back and another plugs in the front: no punch-down tool and no termination work. The numbered ports turn a rat's nest into "port 3 is the NAS, port 7 is the Pi-hole." Rated 4.7 stars by over 240 buyers, though a few report trouble fitting standard keystone modules, so treat it as a finished panel rather than a keystone frame.

Switch

The TP-Link TL-SG108S-M2 has eight 2.5GbE ports, a fanless metal case, and a 6.2 by 4 by 1 inch footprint, small enough to sit on a 10-inch shelf with room for the power cable. It is unmanaged, so there is nothing to configure; Pis link at Gigabit and most current mini PCs link at 2.5GbE. Buyers rate it 4.8 stars, and the main complaint is that it runs warm, which matters in a small enclosure. For more port and speed options, see Best 2.5GbE Unmanaged Switches Under $100 in 2026. If you want to power access points or Pi PoE HATs from the switch, Best PoE Switches for a Home Lab in 2026 covers that path.

Switch shelf

A 1U vented cantilever shelf with a 7.87-inch depth, listed for the T1. It gives the switch a flat, ventilated base, and the vent holes double as anchor points for a cable tie so the switch does not slide when you pull a cable. Buyers say it fits GeeekPi racks well.

Mini PC tray

A 1U shelf built for mini PCs, with an RJ45 keystone and an HDMI pass-through on the front plate. You run the mini PC's own Ethernet and HDMI to the back of those jacks, then plug a monitor or patch cable in at the front without reaching behind the rack. The tray is 43 mm tall, so it suits mini PCs under about 1.7 inches tall; measure yours first. Pick one from Best Mini PCs for a Home Server in 2026, or reuse the host from Proxmox Home Lab Starter Kit: Host, Switch, and Storage.

Raspberry Pi mount

A 2U metal plate that holds up to four Raspberry Pi 5, 4B, 3B+, or 3B boards with their ports facing out, each on a removable front bracket so you can pull one Pi without unbolting the rest. Pi boards are not included. Add active coolers and the parts in Accessories That Actually Work with the Raspberry Pi 5 before mounting, because four boards in 3.5 inches of height share warm air.

Power

The Tupavco TP1713 is a 1U, 10-inch PDU with four NEMA 5-15 outlets, surge protection, a resettable overload switch, a 15A rating, and a 6-foot cord. Its brackets reverse so the outlets can face into the rack. Four outlets is its real limit: the switch, the mini PC brick, and two Pi supplies use them all.

Short patch cables

A 10-pack of 0.5-foot Cat6 cables with snagless boots. Six inches is the right length to jump from the panel down to the switch or from a Pi to the panel without loops of slack. Ten covers four Pis, a mini PC, the uplink, and spares.

What It Costs

About $375 as of writing for the full list, with the rack itself around $150 of that. The switch is about $60, the Pi mount about $45, the PDU about $39, the mini PC tray about $28, the shelf about $24, the patch panel about $16, and the cables about $13. Prices on these mini rack parts move often, so treat the total as a ballpark. Skip the Pi mount if you only run mini PCs, or the mini PC tray if you only run Pis, and the total drops by $28 to $45.

Step-by-Step Setup

  1. Plan the U layout before you build. On paper, number the T1's 8U from the top and place the gear in this order: 0.5U patch panel, 1U switch shelf, 1U mini PC tray, 2U Pi mount, 1U PDU, leaving 2.5U spare for growth or airflow.
  2. Assemble the frame. Build the RackMate T1 on a flat surface, square it, and tighten the rails before mounting anything.
  3. Mount the patch panel at the top. Bolt the 0.5U patch panel into the top half-U so every short cable runs down to the switch below it.
  4. Install the switch shelf and switch. Mount the 1U vented shelf directly under the panel, set the TL-SG108S-M2 on it ports forward, and secure it with a cable tie through the vents.
  5. Add the computers. Mount the mini PC tray next, wire the mini PC's Ethernet and HDMI to the front jacks, then mount the 2U Pi mount with the Pis already screwed to their brackets.
  6. Patch short and label. Use the 0.5-foot Cat6 cables for every panel-to-switch and device-to-panel link, and label both ends or the panel numbers.
  7. Wire power at the bottom. Mount the TP1713 PDU in the lowest U, route bricks and cords down the back corners with straps, and keep power cords away from the Ethernet runs.
  8. Check airflow and heat. Leave the spare U as open space above the Pis, keep the rack off carpet and out of closed cabinets, and check the switch and Pi temperatures after an hour under load.

Limits to Know Before You Buy

Power, heat, and noise set the ceiling on a mini rack long before the 8U runs out.

  • Power: the PDU's 15A rating is far above what a few Pis and a mini PC draw, but it only has four outlets. Four Pis on separate USB-C supplies plus a mini PC and a switch need six plugs, so plan on a multi-port USB-C supply for the Pis or PoE HATs fed from a PoE switch.
  • Heat: the switch runs warm and the Pis share one 2U slot. Active coolers, the open front, and empty U-space are your cooling system; there is no fan in the frame.
  • Noise: the switch, shelf, and PDU are silent. Any noise comes from Pi cooler fans and the mini PC, so pick quiet ones if the rack lives on your desk.
  • Weight: the frame is about 10.5 pounds before gear. Put it on a sturdy surface and avoid stacking anything on the acrylic top.
  • Depth: 7.87 inches rules out full-size rackmount gear. Anything that does not fit on a shelf belongs in a 19-inch rack.
