10 Best Under-Desk Mount Kits for PCs in 2026 for a Cleaner Workspace

A PC on the floor takes up legroom and collects dust. An under-desk mount can keep it off the ground and within reach, but the right choice depends on your case dimensions, desk construction, and how much weight the mount must support.

These 10 options cover standard towers, larger cases, and compact computers, with screw-in and no-drill mounting styles to suit different workspaces.

Best 10 Under Desk Mount Kits for PCs Picks for 2026

Best Swiveling Bracket – VIVO MOUNT-PC01

Among under desk mount kits for pcs, the VIVO MOUNT-PC01 suits buyers who want a steel bracket that swivels for access to rear ports. It can also be wall-mounted.

Best For: Towers up to 22 lb when rear-port access matters.

Pros:

• Adjusts to cases 3.5–7.8 inches wide and 11.5–20.5 inches tall.
• Swivels 135° for cable and port access.
• Padding dots help protect the case from scratches.

Cons:

• 22 lb capacity rules out heavier towers.
• Under-desk installation requires a surface at least 1 inch thick and sufficient desk overhang.

Measure the case, desk thickness, and overhang before ordering; this is a practical choice when the swivel will make connections easier to reach.

Best Full-Rotation Pick – PEGZONE Adjustable Tower Holder

For shoppers comparing under desk mount kits for pcs, the PEGZONE holder offers full rotation and a locking handle for positioning a tower under the desk.

Best For: Towers up to 22 lb whose rear connections need frequent access.

Pros:

• Fits cases 3.5–8 inches wide and 11.8–20 inches tall.
• Rotates 180° in either direction for access to ports and cables.
• Locking handle and 12 anti-skid pad points help hold and protect the case.

Cons:

• 22 lb capacity will not suit heavier builds.
• Case dimensions must fall within the specified width and height ranges.

The rotation is its main advantage over a fixed bracket. Check both your case dimensions and weight before choosing it.

Best Strap-Mounted Option – VIVO MOUNT-PC02S

The VIVO MOUNT-PC02S takes a different approach to under desk mount kits for pcs: adjustable straps secure a range of case shapes beneath the work surface.

Best For: Unusually shaped cases or towers up to 44 lb that fit the stated strap range.

Pros:

• Two adjustable anti-skid straps accommodate a broad range of case dimensions.
• Supports up to 44 lb.
• Slotted mounting plates allow width and depth adjustment after fastening.

Cons:

• Requires fastening plates to the underside of the desk.
• Case fit depends on the strap dimensions and approximately 60-inch maximum perimeter.

Check your case perimeter and desk mounting area first. If they fit, the straps provide an alternative to rigid side brackets.

Best No-Drill Standing Desk Pick – JOY worker Clamp-On PC Mount

Unlike under desk mount kits for pcs that screw into the desktop, this JOY worker holder clamps to a standing-desk leg. That keeps the tower moving with the desk without drilling the work surface.

Best For: Standing desks with compatible non-round legs and 5.9–9.8-inch-wide towers.

Pros:

• Clamp-on installation needs no drilling.
• Supports towers up to 44 lb.
• Upgraded silicone gaskets are designed to help prevent slipping.

Cons:

• Not compatible with round desk legs; works best with inverted legs.
• Only fits cases 5.9–9.8 inches wide.

The leg-mounted design is the key distinction. Confirm your desk-leg shape and tower width before choosing it over a conventional underside bracket.

Best for Tall Towers – VIVO Heavy-Duty Under-Desk PC Mount

Among under desk mount kits for pcs, this VIVO steel-frame holder is a practical choice for a tall tower: its five height settings span 16 to 24 inches, and its width adjusts from 5 to 10 inches. It supports cases weighing up to 66 pounds.

Best For: Taller PC cases that fit its adjustment range and desks that meet its mounting requirements.

Pros:

• Open frame leaves room for airflow and access to ports.
• Thick inner padding helps protect the case from scuffs.
• Adjustable frame accommodates a range of case heights and widths.

Cons:

• Requires a desktop at least 0.75 inch thick and 8.5 inches of clearance from the frame to the desk edge.
• Its 66-pound capacity is lower than the 77-pound ratings of the other two mounts here.

Check your case dimensions and the space beneath your desk before choosing it; the generous height range is most useful when both fit.

Most Flexible Orientation – PUTORSEN Under-Desk PC Mount

If you are comparing under desk mount kits for pcs with limited floor space, the PUTORSEN stands out for its choice of vertical or horizontal installation. Its reinforced steel brackets support a mid- or mini-tower weighing up to 77 pounds.

Best For: Mid- and mini-tower owners who want to choose an orientation that suits their under-desk layout.

Pros:

• Offers vertical and horizontal mounting options.
• Supports PC cases up to 77 pounds.
• Open-frame construction allows ventilation and cable access.

Cons:

• Fit limits differ by orientation: vertical width is 6 3/16 to 10 5/8 inches with height up to 19 1/4 inches; horizontal width is 13 1/2 to 25 11/16 inches with height up to 12 11/20 inches.

The two mounting modes are its main advantage, but measure your case against the dimensions for the specific orientation you plan to use.

Best Installation Extras – Ultimate Setup Heavy-Duty PC Holder

For shoppers looking at under desk mount kits for pcs and wanting installation supplies included, this Ultimate Setup holder comes with a drilling template, screws and a suitable drill bit. Its steel construction has two support pillars and is rated to hold up to 77 pounds.

Best For: Buyers who value an included drilling template and protective pads for their under-desk installation.

Pros:

• Includes a drilling template, screws and a drill bit.
• Rubber protective pads help cushion the PC case.
• Ventilation slots allow airflow around the mounted case.

Cons:

• The supplied notes do not specify exact case-fit adjustment ranges, so verify your tower’s dimensions before buying.
• Mounting involves drilling into the desk.

Its included mounting items simplify preparation, while the unspecified fit range makes measuring your tower and available desk space especially important.

Heavy-Duty Tower Pick – 66 lb Adjustable Under-Desk PC Mount

For shoppers comparing under desk mount kits for pcs, this steel-frame option is designed to lift a mid-tower off the floor. Its adjustable height and open frame make it a practical choice when you want clearance around the case and easier access to ports.

Best For: Tower owners who can screw a mount under their desk and need support for a case up to 66 lb and 9.6 inches wide.

Pros:

• Reinforced steel frame and rectangular base support up to 66 lb.
• Height adjusts from 17.3 to 25.1 inches.
• Open-frame design leaves room for airflow.
• Includes installation hardware and instructions.

Cons:

• Cases wider than 9.6 inches will not fit.
• Requires under-desk mounting rather than a no-drill clamp.

This is the capacity-focused choice of the three, but measure your case width and available under-desk space before buying.

Best Heavy-Duty Pick – TOPSKY Leg-Clamp PC Mount

Among under desk mount kits for pcs, this TOPSKY holder stands out for clamping to a compatible electric standing-desk leg instead of requiring holes in the desktop. It keeps a rectangular tower off the floor while moving with the desk.

Best For: Owners of compatible standing desks who want a no-drill mount for a standard or mid-tower PC weighing up to 50 lb.

Pros:

• Clamp installation requires no drilling or special tools.
• Supports up to 50 lb with top-and-bottom clamping.
• Accommodates case widths from 6.89 to 11.22 inches.
• Open frame allows airflow around the case.

Cons:

• Only fits rectangular desk legs measuring 65 × 45 mm, 75 × 45 mm, or 80 × 50 mm.
• Recommended case height is no more than 21.65 inches; oversized full towers are not recommended.

The drill-free setup is appealing, but desk-leg dimensions are the deciding factor: measure yours before ordering.

Compact Device Pick – Under-Desk Laptop and Mini PC Brackets

If your search for under desk mount kits for pcs is really about storing a thin mini PC or laptop, these screw-in brackets offer a smaller-scale solution than a tower holder. Soft padding helps protect the device where it contacts the mount.

Best For: Slim laptops or mini PCs less than 1.85 inches thick and weighing no more than 6 lb, mounted beneath a desktop at least 0.78 inch thick.

Pros:

• Designed for devices less than 1.85 inches thick.
• Soft padding helps prevent scratches.
• Includes six screws and a mounting template to help position the holes.

Cons:

• 6 lb capacity rules out typical desktop towers.
• Requires screws and a desktop at least 0.78 inch thick.

Choose this for compact-device storage rather than tower mounting, and verify both device thickness and desktop thickness before installation.

How We Picked the Best Under Desk Mount Kits for PCs

We focused on practical differences that affect fit and installation: supported case size, stated weight capacity, mounting method, and whether the holder is intended for a tower, mini PC, or laptop. The selection includes screw-in mounts, a clamp-on option, and a no-drill holder. Product names and listed capacities are a starting point, not a substitute for checking the manufacturer’s current specifications before buying.

Quick Comparison: Which Style Fits Your Setup?

• Standard tower: Start with an adjustable under-desk holder such as the VIVO MOUNT-PC01, PEGZONE, or PUTORSEN, then confirm your case’s width and height fall within its adjustment range.
• Large or heavy tower: Compare the VIVO MOUNT-PC04B with the listed 66 lb and 77 lb heavy-duty options. Check both the rated load and the size of the support platform.
• Desk you cannot drill: Look at the JOY worker clamp-on leg holder or TOPSKY no-drill mount, provided your desk or leg shape is compatible.
• Mini PC or laptop: Choose the dedicated compact-device storage mount rather than a tower cradle that may be too wide.

Key Buying Factors for Under Desk Mount Kits for PCs

Measure the PC and the Clearance

Measure your computer’s width, height, and depth, including feet or protruding panels. Leave room around vents, power plugs, and cables; a snug fit should not block airflow. If you use a standing desk, check clearance at its lowest height and through its full travel so the PC and cables cannot hit the floor or nearby furniture.

Check the Desk Before Choosing a Mount

Screw-in mounts need a desktop that can securely hold the fasteners. Confirm the surface material, thickness, and available space underneath before drilling. Clamp-on and other no-drill designs avoid holes, but they still require a compatible edge or leg and enough clearance for their hardware. Do not assume a stated weight rating applies to every desk construction.

Look Beyond the Weight Rating

Weigh the complete computer, not just the empty case, and stay within the mount’s stated limit. For a heavier tower, also check how the mount supports the base and restrains the case. Straps, such as those on the VIVO MOUNT-PC02S, may be useful if you want additional retention. Plan cable slack before installation, especially if the PC will move with an adjustable desk.

Who Should Buy Which Under Desk Mount Kits for PCs?

Buy an adjustable tower holder if you have a typical desktop PC and want to reclaim floor space. Choose a heavy-duty model only after confirming both your loaded PC weight and case dimensions. A clamp-on or no-drill option is the more practical starting point when drilling is not allowed, while a purpose-built compact mount makes more sense for a mini PC or laptop. Whatever you choose, fit, desk compatibility, and unobstructed ventilation matter more than a headline capacity alone.
