PC Building in San Diego: Custom Builds, Reassembly After a Move, and Where 3D Printing Helps
Sometimes a PC arrives in San Diego as a box of loose parts. Here’s how we put it back together, what it costs, and where a 3D printer makes the build better.
We got a text recently that went roughly like this: I’m moving to San Diego. I took my PC apart to ship it. Can someone put it back together, in a new case, at my place? Then, a line later: and it was blue-screening before I moved. Probably the RAM.
That one conversation covers most of what we do with computers at Dreaming3D. We build custom PCs from scratch, reassemble machines people already own, and chase down crashes. And because we run a 3D printing shop, we can make the small parts a new case or an old build is missing. This post walks through all of it with real prices, the order we assemble in, the 13th-gen Intel problem that gets mistaken for bad RAM, and which plastics survive inside a hot case.
What we do with PCs in San Diego
| Service | Where | Price (Sept 2026) |
|---|---|---|

| 3D printed PC parts (sleds, combs, supports, badges) | Printed in-house | $7/hr FDM machine time, plus design time for custom parts |
The reassembly prices assume a typical tower: motherboard and CPU, an AIO liquid cooler, one graphics card, up to four RAM sticks, a couple of drives, and a modular power supply. We confirm the number once we see the parts. Custom water loops, small-form-factor cases, and anything with hard tubing get their own quote because the work is different.
If you’re still choosing parts, our custom gaming PC builds for 2026 breaks down budget, mid-range and flagship configurations, and the BECT Gamers build shows what a finished Dreaming3D system looks like.
Reassembling a PC after a move: what to have ready
Most reassembly delays come from missing small parts, not from the build itself. Before we arrive, or before you drop parts off, gather these:
- The CPU cooler’s mounting hardware. AIO coolers ship with brackets and backplates for several sockets. Without the right one, the pump can’t be mounted.
- The power supply’s own modular cables. Only the cables that came with that PSU. More on this below, because it’s the one mistake that can kill parts.
- Motherboard standoffs and the I/O shield if your board doesn’t have one built in. New cases usually include standoffs; I/O shields come with the board, not the case.
- Drive screws and the M.2 screw. The tiny M.2 screw is the part most likely to be lost in a move.
- The new case’s accessory box. Fan screws, cable ties, and any drive sleds live in there.
- Photos of the old build, if you have them. They help us match fan directions and cable routing to what worked before.
The mistake that kills drives
Modular power supply cables look universal, and the plugs often fit other brands. They aren’t universal. Pin layouts on the PSU end differ between manufacturers and sometimes between models from the same brand, so a mismatched cable can put 12 V where a drive or graphics card expects something else. If you’re moving to a new power supply, the old cables stay in the drawer.
The order we reassemble in
Here’s our reassembly sequence for a typical tower like the one in that message: an i9, an AIO, an RTX-class card, four sticks of RAM, one SSD and one hard drive.
- Inventory and inspect everything. Unbox every part and check it against the list before a single screw goes in. Look for shipping damage: a cracked AIO tube, a dented radiator, a bent GPU bracket, and, with the socket cover still on, the CPU socket area of the motherboard. Count the small stuff: standoffs, the AIO mounting bracket and backplate, drive screws, and the PSU's own modular cables.
- Build the core outside the case. On the motherboard box, install the CPU, the RAM (in the slots the board manual lists for four sticks), and the M.2 SSD. Fit the AIO backplate or bracket now if the cooler needs one. Working on the bench is faster and far easier on the socket than doing it inside the case.
- Prep the new case. Match standoffs to the board's mounting holes, remove any extra standoffs that would short the board, fit the I/O shield if the board doesn't have one built in, and install the power supply.
- Mount the motherboard. Lower the board onto the standoffs, line up the rear I/O, and screw it down evenly without overtightening.
- Install the AIO. Mount the radiator (top or front, depending on the case), orient the fans for the airflow plan, then seat the pump block with thermal paste and tighten it in a cross pattern. We route the tubes so the pump isn't the highest point in the loop.
- Install the drives. SATA SSD and 3.5-inch HDD go into the case's sleds or bays. If the new case dropped its 3.5-inch cage, this is where a printed adapter sled earns its place.
- Install the graphics card. Seat the card fully in the top x16 slot, fasten the slot screws, and connect GPU power with the connector fully latched. Add a support post if the card sags.
- Wire it up. 24-pin, CPU EPS power, front-panel headers, USB and audio, fans, and the pump header. We use only the modular cables that shipped with that exact power supply, then comb and tie the runs for airflow.
- First boot into BIOS, then Windows. Before Windows loads we confirm all four RAM sticks and both drives are detected, check CPU temperatures at idle, update the BIOS if it's behind, and load safe defaults. Then we boot Windows, check Device Manager, and run a stress and memory pass before calling it done.
Before you blame the RAM: 13th and 14th Gen Intel crashes
Back to that blue screen. When a machine with an Intel Core i9-13900K or 13900KF crashes, RAM is the natural suspect. Sometimes it’s right. But this generation has a documented CPU issue that produces the same symptoms, so we check that first.
Intel calls it Vmin Shift Instability. In its current support article (last reviewed July 21, 2026), Intel says it affects some 13th and 14th Gen Core desktop processors, recommends running a BIOS that contains microcode 0x12F or later along with Intel Default Settings, and has extended the warranty on eligible chips by two years, to up to five years from the original purchase date. Intel’s root-cause write-up traced the damage to elevated voltage, including board power settings above Intel’s guidance.
The catch, as TechSpot and others have noted: the microcode updates prevent damage, but they can’t reverse it. A chip that was already crashing before the update may keep crashing after it. That’s a warranty case, not a settings problem.
Our diagnostic order
- Update the BIOS to a version with microcode 0x12F or later, load Intel Default Settings, and remove any manual overclock or undervolt.
- Turn off XMP or EXPO and test memory at stock speed. Four sticks at XMP speeds are harder on the memory controller than two, and many boards list lower supported speeds for four-stick setups.
- Test RAM a stick or a pair at a time to isolate a bad module.
- Read Windows’ Event Viewer for WHEA errors and check the crash dump codes.
- If crashes continue at Intel’s defaults with known-good memory, document it and start the warranty process with Intel or the system builder.
We’ll tell you honestly which way the evidence points before recommending you buy anything. Replacing four sticks of RAM to fix a CPU problem is an expensive guess.
Where 3D printing helps inside a PC
This is where running a print shop pays off. New cases often drop features the old one had, like the 3.5-inch drive cage. Moves lose small parts. Big graphics cards sag. A printer and some CAD time fix all of that, as long as the plastic can handle the heat.
Parts worth printing
- 3.5-inch drive sleds and adapters. If your new case has no hard drive cage, a sled that bolts to the shroud or a fan mount keeps the HDD from rattling loose. Printed in PETG.
- Cable combs. They keep the 24-pin and GPU power runs neat and out of the airflow. PETG for anything in the main chamber.
- GPU support posts. A post under the front end of a long card stops sag over time. It sits right in the card’s exhaust, so we print it in ASA-CF. It supports the card; the slot and its screws still hold it.
- Fan spacers and ducts. Spacers let a radiator clear tall RAM, and ducts steer airflow. They live in warm air, so ABS or ASA.
- Replacement I/O shields. If the shield was lost in the move, a printed one closes the gap and keeps dust out. It won’t have the original’s metal grounding tabs, so a replacement from the board maker is still the better long-term fix.
- Badges and nameplates. Cool spots like the PSU shroud are the one place PLA is fine.
For a broken proprietary part, like a snapped side-panel clip or a discontinued drive tray, we can 3D scan what’s left and model a replacement. Our reverse engineering guide covers how that works and what it costs.
Why PLA is the wrong default inside a case
PLA is the plastic most people print first, and it’s a poor fit near anything hot. Bambu Lab’s filament guide says PLA isn’t recommended in environments around 50 °C or higher because it may slowly soften and deform, and its PLA Basic data sheet lists a heat deflection temperature of 57 °C. Warm exhaust from a graphics card or a radiator under load can reach that range.
| Material | HDT, 0.45 MPa (Bambu) | Where we use it in a PC |
|---|---|---|
| PLA Basic | 57 °C | Badges and trim in cool spots only |
| PETG HF | 69 °C | Drive sleds, cable combs, brackets away from exhaust |
| ABS | 87 °C | Fan spacers, ducts, parts in warm airflow |
| ASA-CF | 110 °C | GPU support posts, parts near the card |
| PC FR | 113 °C | Flame-retardant option for parts near power cabling |
Values are Bambu Lab’s published typical figures from its filament guide and data sheets (ASA-CF, PC FR). Heat deflection is a lab test on a standard bar, not a rating for your part. Thin walls, low infill, and constant load all lower the real limit, which is why we leave margin.
What we won’t print for a PC
Nothing that goes inside a power supply, replaces an electrical connector or its insulation, or acts as a heatsink or thermal pad. No printed part is the only thing holding up a graphics card. These are safety calls, and a printed part isn’t the right answer for any of them.
San Diego notes
- Lots of people arrive with a PC packed flat. Between military moves, students, and people relocating for work, shipping a tower in pieces is common. Reassembly at your new place means nothing gets loaded back into a car.
- Inland summers change the math. A room in El Cajon, Santee or Escondido in August runs a lot warmer than one on the coast, and every degree of room temperature shows up inside the case. That’s another reason we skip PLA for internal parts.
- Coastal humidity affects the printing, not just the PC. PETG and ABS absorb moisture from marine-layer air and print worse for it, so we dry filament before functional parts. Our filament dryer guide explains why.
Frequently asked questions
Do you reassemble a PC from parts I already own?
Yes. For a typical full reassembly into a new case (motherboard and CPU, AIO cooler, graphics card, RAM, a couple of drives, PSU and cables), we charge $250 at our shop or $300 at your place. We confirm the price once we see the parts; custom water loops and unusual cases are quoted separately.
Can I reuse the modular cables from my old power supply with a new one?
No. Modular cable pinouts differ between manufacturers and sometimes between models from the same brand, so a cable that fits the socket can still send the wrong voltage to a drive or graphics card. Use only the cables that came with the power supply you're installing.
My i9-13900K or 13900KF blue-screens. Is it the RAM or the CPU?
It can be either, which is why we check the CPU side first. Intel says some 13th and 14th Gen desktop processors are affected by Vmin Shift Instability, recommends a BIOS with microcode 0x12F or later plus Intel Default Settings, and has extended the warranty on eligible chips to up to five years from purchase. A BIOS update helps prevent further damage but doesn't repair a chip that is already unstable. After that we test memory with XMP off, stick by stick.
Is PLA safe to use for parts inside a PC case?
For parts that sit in cool spots, like a badge on the PSU shroud, usually yes. Bambu Lab says PLA isn't recommended in environments at about 50 °C or higher because it can soften and deform, so anything near the GPU, in exhaust airflow, or near a radiator should be PETG, ABS, ASA or polycarbonate instead.
Can you 3D print a missing I/O shield, drive bracket, or case clip?
Usually. Drive sleds, cable combs, GPU support posts and case clips are good printed parts. A printed I/O shield fills the gap and keeps dust out, but it doesn't have the metal grounding tabs of the original. For a broken proprietary clip we can scan the old piece and model a replacement.
Will a 3D printed GPU support hold up my graphics card?
It helps with sag, but it isn't meant to carry the card on its own. The slot screws and the PCIe slot still do the holding. We print supports in heat-resistant material like ASA-CF, because they sit right in the card's exhaust.
