A clean cable job does more than look good through a glass side panel. Tidy routing keeps airflow paths open, makes future upgrades painless, and turns a nest of wires into something you’re proud to show off. The goal here is simple. Get every cable off the main chamber, tucked behind the motherboard tray, and secured so the front of your build looks like a product photo. This walkthrough takes you from an empty case to a finished loom, step by step, with the specific numbers and habits that separate a rushed job from a clean one. It doesn’t require special skill. Just patience and a plan.
Before you start, it helps to know your case, because layout dictates strategy. Cases built for cable management give you a deep gap behind the tray, plenty of tie-down points, and routing channels near the edges. If you’re still choosing a chassis, our picks for the best mid tower cases and the best cases for airflow lean toward designs that make this whole process easier. Let’s get into it.
What you’ll need
You don’t need much. A Phillips screwdriver, a small pack of zip ties or reusable Velcro straps, and a pair of flush cutters or scissors to trim the tie tails. Velcro straps are the friendlier choice since you’ll redo the loom a few times before it’s perfect. Keep the cable combs or clips that shipped with your PSU if it came with any. And clear a flat, well-lit workspace so you can lay the case on its side without fighting gravity.
The case itself does most of the heavy lifting. A chassis with a back-connect design, where the motherboard’s power and data headers face the rear, hides nearly every cable before you even start tying. The Lian Li O11 Vision Compact is a good example at $124.99 with a 4.4 rating. It’s an ATX mid tower with tempered glass and explicit back-connect support, so pairing it with a reverse-connector motherboard means the front chamber stays almost wire-free. If you’re building fresh, that kind of layout saves you an hour of fiddling.
Pros
- Patented three-panel tempered glass exposes front, top, and left views of the build.
- Native back-connect motherboard support for hiden 24-pin, EPS, and PCIe cabling.
- Second chamber hides side-mounted AIO tubing for a cleaner primary compartment.
- Swappable top mesh panel suports a 360mm AIO when thermals take priority over glass.
Cons
- Limited owner feedback at time of writing makes long-term reliability signal thin.
- Full specs (GPU length, cooler height, fan count) not published in source data.
- Back-connect layout requires a compatible motherboard, narowing part selection.
The Lian Li O11Vision Compact is a mid-range ATX mid-tower positioned as a smaller sibling to the O11 Dynamic line, developed in collaboration with the PCMasterRace community. It targets showcase builders who want a dual-chamber layout, tempered glass on three sides, and native support for back-connect motherboards in a tighter footprint.
The defining feature is the patented three-panel tempered glass design covering the front, top, and left side. Paired with the second-chamber cable routing and back-connect motherboard compatibility, the front compartment stays visually clean. Builders wanting a 360mm AIO can swap in the included top mesh panel, trading a glass top for airflow.
Trade-offs are typical at this tier. Back-connect support only pays off if you buy a compatible board from ASUS, MSI, GIGABYTE, or similar, which narrows part selection and can raise motherboard cost. Concrete specs like GPU clearance, CPU cooler height, radiator sites, and included fan count are not specified in the source data, so verify against the official manual before finalizing parts.
Buy this if you want O11-family aesthetics with hidden cabling via a back-connect board and a side or top 360mm AIO. Skip this if you need a documented GPU length ceiling, bundled fans, or a traditional cable-visible motherboard build.
Motherboard support: The chassis accepts standard ATX boards and ads native routing for back-connect variants such as ASUS BTF, MSI Project Zero, and GIGABYTE Project Stealth. Cable cutouts on the tray align with rear-side connectors, keping the 24-pin, EPS, and PCIe cables out of the main chamber view.
Radiator and AIO: A swappable top mesh panel is included specifically to enable a 360mm AIO in the rof. When the AIO is mounted on the side instead, the dual-chamber layout routes the tubing into the second compartment, keeping the front-facing glass view unobstructed. Exact side radiator thickness limits are not specified.
Glass and panel layout: Three tempered glass panels cover the front, top, and left side. The top glass panel is the one you swap out when a 360mm radiator is installed, so builders choosing air cooling or a bottom-mounted AIO retain the full three-panel glass look.
Not specified in source: GPU length clearance, CPU cooler height, drive bay count, included fan count, front I/O (USB-C, USB-A), PSU length, and case dimensions are not listed in the provided data. Confirm these against the Lian Li O11VPW official spec sheet before finalizing parts.
Step 1: Plan the routing before plugging anything in
Resist the urge to start connecting cables right away. First, lay out where each one needs to go. The big four are the 24-pin motherboard power, the 8-pin (or dual 8-pin) EPS CPU power up top, the PCIe power for your GPU, and the SATA or front-panel bundle. Map each from its source at the PSU to its destination on the board, and note which rubber grommet or cutout it should pass through.
Most modern cases put a grommet right beside the 24-pin header and a cutout at the top-left for the EPS cable. Feed cables through the closest opening to their plug, not the most convenient one. A cable that travels the shortest visible distance looks cleanest. Take thirty seconds to picture the finished layout now, and you’ll avoid unplugging things three times later.
If your case supports a back-connect motherboard, the plan changes for the better. With the headers on the rear of the board, the 24-pin and front-panel cables never cross the visible chamber at all, so your planning shifts to the back side entirely. Either way, a quick habit helps: connect and route one cable fully before starting the next. Jumping between half-finished runs is how looms turn into knots.
Step 2: Install the PSU and route the main power cables
Mount the power supply with its fan facing the bottom vent if your case has a filtered floor, which nearly all do. Connect the modular cables at the PSU end first, while you still have room to reach the sockets. Only plug in what you actually need. Leftover modular cables just add bulk, so leave the unused ones in the box.
Run the 24-pin through the grommet nearest the header, then the EPS cable up and through the top cutout to reach the 8-pin near the CPU socket. The EPS cable is often the trickiest, so route it before the GPU and motherboard block access. Leave a little slack at each plug so nothing tugs on the connector, but pull the rest back through so the excess sits behind the tray, not bunched in front.
Step 3: Handle the GPU and PCIe power
With the graphics card seated, route its power cable from the PSU up through the grommet closest to the card’s connector, usually the middle-right or top-right opening. Modern GPUs use a 12V-2×6 or dual 8-pin connector that must click fully home, so seat it firmly and check for the audible snap. A half-seated GPU power connector is a real fire risk, not a cosmetic one, so this step earns your full attention.
Once it’s plugged in, gently coax the visible portion of the cable so it runs straight from the grommet to the card with a soft, even curve rather than a kink. If your PSU shipped with a cable comb, use it here to keep the individual wires parallel. This single cable is the most visible one in the whole build, so it’s worth an extra minute to make it lie flat.
A word on the newer 12V-2×6 cables that ship with high-end GPUs. They’re stiff, and forcing a tight bend right at the connector can stress the pins, so give the cable at least an inch of straight run out of the plug before it curves. If you’re using a native cable from an ATX 3.1 PSU rather than an adapter, you’ll have fewer wires to wrangle and a cleaner look, since the adapter octopus is the ugliest thing in most builds. Route it, don’t fight it.
Step 4: Route the small cables and front-panel headers
The fiddly ones come next. Front-panel connectors (power switch, reset, HDD LED, the tiny two-pin plugs), USB headers, the front-panel audio cable, and any fan or ARGB leads. These are thin and tend to look messy because there are so many of them. Group them by destination. Bundle everything heading to the bottom-front corner of the board together, run it behind the tray, and bring it through the nearest cutout.
SATA power and data cables for drives get the same treatment. Daisy-chain SATA power to multiple drives on one cable rather than running separate leads. Keep fan cables tucked along the frame edges and consider a small fan hub or the motherboard’s headers to cut down on the number of wires crossing the open area. Every wire you keep out of the main chamber is one less thing breaking up the view.
ARGB lighting is the sneaky offender here, since every fan and strip wants its own 3-pin lead back to a controller. A dedicated ARGB hub mounted behind the tray collapses six or eight of those into a single cable to the board, which cleans up the front dramatically. If your case came with a built-in hub, use it. Label nothing, but do keep a mental map of which header feeds what, because untangling a mislabeled RGB loom six months later is nobody’s idea of fun.
Step 5: Tie it all down behind the tray
Now the satisfying part. Flip the case to the back side and work the loom into shape. Pull each cable snug so there’s no slack ballooning behind the tray, then anchor it to the built-in tie-down points with a Velcro strap or zip tie. Cases with a deep rear channel let you run the fat 24-pin along a dedicated groove, so use it. Aim for a strap roughly every four to six inches along each run so cables stay flat instead of bowing outward.
Keep tension even and the runs parallel where they travel together. Don’t cinch so hard that you crush a cable, but firm enough that nothing shifts when you move the case. If your PSU shroud has a cover, make sure the side panel still closes without bulging. A rear panel that won’t sit flush is the classic sign of too much cable stuffed in one spot. Redistribute and try again. Trim any zip-tie tails flush so they don’t catch a finger later.
Before you call it finished, do a dry run of the panel. Set the rear cover on loosely and feel for where it resists. Any spot that pushes back is a cable you need to flatten or reroute. It’s tempting to force the panel and let the screws hold it, but a bulging cover warps over time and traps heat against the wires. Five extra minutes spreading the loom out now beats redoing it after the first thermal complaint. Once the panel seats with light pressure, you’re done.
If something goes wrong
The back side panel won’t close
This is the most common frustration, and it almost always means too many cables are bunched at one point behind the tray. Open it back up, find the fat spot (usually where the 24-pin meets the front-panel bundle), and spread the cables out across the available depth. Route some through a different channel. If your case has a shallow rear gap, prioritize keeping the thick 24-pin in the deepest groove and let thinner cables ride elsewhere.
A fan won’t spin or an LED strip stays dark
When you route cables aggressively, it’s easy to leave a header half-seated or route a lead to the wrong pin. Double-check the connector is fully home and on the correct header. ARGB and PWM connectors look similar but aren’t interchangeable, so confirm the 3-pin 5V ARGB lead didn’t end up in a 4-pin 12V RGB header, which can damage the strip.
Cables droop into the fan or GPU after a while
If a cable sags into a spinning fan, you didn’t secure it close enough to the source. Add a tie-down point nearer the connector so there’s no unsupported span long enough to droop. A cable clipped by a fan blade makes a clicking noise and can eventually cut through insulation, so fix any sag the moment you spot it.
Wrapping up
Cable management isn’t about being an artist. It’s about routing each wire the shortest visible distance, hiding the excess behind the tray, and anchoring everything so it stays put. Do that and even a first attempt looks sharp. The payoff shows up later too, when you swap a GPU or add a drive and every cable is already labeled by its neat run instead of buried in a tangle. If you’re pairing this with a build focused on quiet operation or a clean showcase, our guides to the best cases for a showcase build point you toward chassis that reward the effort. Take your time on the first loom, and the next one will go twice as fast. A tidy build isn’t just prettier, it’s easier to live with every time you open the panel.
