Setup, power and thermals, and software tips for running a Mac mini as a home server or self-hosting box.
A Windows-focused IT technician has bought a Mac mini and wants to relearn macOS from the beginning. They knew Macs about 10 years ago, but many terms and work steps for business use have changed since then. The goal is to become comfortable as a Mac user first, then prepare for the ACSP certification. They are looking for a beginner course on simply using a Mac before moving into certification study. An old plastic MacBook is still around but is too slow for practical learning, and they also use an iPhone and Apple Watch.
A Kettop MI19C mini PC is being used as a first homelab device. The main goal is to replace an Android TV or Google TV-style living room media device. The hardware has 8GB of memory, a 64GB NVMe SSD, a 128GB SSD, and a Celeron J1900 processor. It also has two wired network ports, four USB ports, one HDMI port, one VGA port, and one COM port. It supports Windows and Linux. The possible apps include Pi-hole, AdGuard, Stremio, and Plex, with the main question being which apps and GNU/Linux distribution fit media use and network management best.
The main question is whether Ubuntu 10.04 LTS Server Edition can run well on a 2015 Mac Mini. The target system is the server version of Ubuntu, not the regular desktop version. This directly fits the use case of turning a Mac Mini into a small personal server. The main caveat is age: Ubuntu 10.04 is very old, so security updates and support for newer software matter more than basic installation alone.
A large personal collection of physical books is currently being tracked in LibraryThing. The goal is to move that catalog to a self-hosted setup instead of relying on an outside service. Koha is one possible option, but it may be too large and complex for simple personal use. The real need is a lighter tool for keeping and managing a private book catalog on a server.
A low-cost home server was built from AliExpress parts plus reused and second-hand drives. The goal is to run both a NAS for shared storage and a home server for self-hosted services. The main parts are an Intel Xeon 2680v4 processor, an X99 Machinist motherboard, 32GB ECC DDR4 memory, a GT 710 graphics card, a Jonsbo N4 case, and a Lian Li 750W Gold SFX power supply. A 128GB NVMe drive is used for booting and fast storage, while bulk storage is split into two ZFS RAID pools: four 1TB hard drives in one pool and two 1TB hard drives in another. The service stack includes Dockge, Nginx Proxy, AdGuard DNS, Fan Control, Uptime Kuma, System Stats, and Scrutiny. The practical aim is to depend less on cloud services and learn by running local services directly.
An old Netgear network switch failed and took home services offline. Home Assistant and Plex had to come back quickly for the family, so replacing the hardware was faster than spending more time troubleshooting. A larger new TP-Link switch restored the setup. Cable cleanup is still left to do.
Firefly-Pico 1.11 has been released. Firefly-Pico is a companion web app for Firefly III. It is made for mobile use and focuses on making expense tracking faster and easier. This version adds support for managing recurring transactions. It also adds support for managing piggy banks. The full changelog is available on GitHub. New feature suggestions are welcome.
During home redecorating, an electrician moved switches and power outlets, along with a TV aerial jack and an Ethernet port. After the work was finished, the Ethernet port no longer worked. For a Mac mini used as a home server, this kind of small wiring fault can mean the server becomes hard or impossible to reach over the home network.
An iPad can be used as a second monitor for a Mac mini, but in this setup the iPad touchscreen does not directly control the Mac. The desired setup is not just showing the Mac screen on the iPad, but also using finger taps on the iPad as input for the Mac. The practical question is whether the iPad can act like both a display and a mouse or trackpad for the Mac mini.
A home-maintenance setup now depends on a large Excel spreadsheet, but a more purpose-built self-hosted app would fit better. The records include maintenance schedules, home improvement logs, and appliance details. Appliance details include serial numbers and install dates. Recurring tasks are currently handled well by Microsoft To Do. Home Assistant integrations have been tried, but they do not work as well as Microsoft To Do for recurring task management.
Aphrodite has been archived on GitHub since November 13, 2025. It appears to have received no updates since then. It now feels outdated for continued use. A working and actively updated replacement is needed, but no specific alternative is named here.
Vaultwarden is not showing site icons for saved self-hosted services. For example, the FreshRSS address `https://freshrss.beispiel.dynv6.net` has no icon in the saved item. Normal public sites such as `https://www.google.de` still show their icons correctly. The problem seems limited to self-hosted service addresses, and it is unclear whether a Vaultwarden setting is missing or another setup issue is causing it.
A 3D-printable storage insert makes it cheaper to organize many spare drives. You enter the inside measurements of any cardboard box in millimeters, then download printable files sized for that box. The printed parts create separate sleeved slots for 3.5-inch hard drives and 2.5-inch SSDs. The main idea is to reuse a normal cardboard box instead of buying expensive custom protective cases. 2.5-inch hard drives are not supported yet because they are a little thicker than 2.5-inch SSDs.
The main question is whether a Mac mini listed on Amazon as “used - like new” is a safe purchase. No specific model, price, seller, warranty status, or return window is provided. A real decision would need those details, especially the condition notes, who is selling it, whether returns are allowed, and whether Apple warranty coverage can still be checked.
A Zimaboard 2 has been running every day for three months inside a custom 3D printed case. It uses ZimaOS 1.6 and has stayed stable over that period. When the container stack is active, normal load is about 56% CPU use and 38% memory use. The case was designed and printed by the owner, and the STL files can be shared so others can print the same enclosure.
The home media server setup is still new. The available gear is a 4TB Synology Beestation and an HP mini PC with an Intel Core i5-8500T. Movies are played through Plex on a Samsung Smart TV and a Walmart Onn 4K box. Playback works fine on the Samsung Smart TV, but it becomes laggy on the Onn 4K box. The main question is whether the problem comes from the server setup or from the Onn box itself.
DokuWiki can be expanded with plugins and templates for common wiki needs. The listed set includes Bootstrap Wrapper, cleanup, bpmnio, Changes, DataTables, diagrams, DOI, DW2PDF, Faster DokuWiki, Folded, ImgPaste, Katex, MindTheDark Template, Move, sectiontoggle, ToDo, and Video Share. The features cover page layout, cleanup, change tracking, table display, diagrams, PDF export, speed improvement, image pasting, math display, a dark theme, moving pages, collapsible sections, task tracking, and video sharing. Version dates are included, which helps separate older add-ons from ones that appear to have been updated more recently.
About 20 old hard drives are available, with sizes from 40GB to 320GB, and all of them still work. The first idea was to use 6 of them in an old PC to build a 1TB DIY NAS. That plan no longer looks practical because 1TB is small for a NAS today, and keeping an old PC plus several drives running could cost more in electricity than buying a cheap 1TB external drive. The drives have healthy SMART checks, and some have fewer than 800 hours of use. The real question is not how to get cheap storage, but how to use the drives for a fun or useful short-term project.
SoulSync and Aurral can help replace parts of Spotify, but they still feel weak for finding new music. Aurral is improving its music discovery tools by adding weekly discovery and new-release playlists, but new tracks can only be previewed for 30 seconds before they are downloaded. That makes it hard to browse freely and listen before deciding what to keep. SoulSync works well for syncing and downloading Spotify playlists, and it can work with other platforms too. The problem is that Spotify can often block its API access. SoulSync also does not solve the bigger issue: new music usually has to be downloaded before it can be played freely. Its interface also feels cluttered, with too many windows, popups, and tabs to keep track of easily. Replacing Spotify with a self-hosted music setup may still take more effort than it is worth if music discovery is the main goal.
Mac Mini M4 units are hard to find on store shelves in Australia. The wanted setup is a smaller-storage model, not anything above 512GB. The main question is where to find this lower-storage Mac Mini M4 in Australia at a good price.
A local setup with two 16 GB 5060 Ti graphics cards ran the Qwen3.6:35b model at about 234,000 tokens per minute. The system used Ubuntu with Ollama and Openclaw. The concrete takeaway is that a personal machine with two graphics cards was used to run a large language model locally, with a specific speed number reported.
A separate temporary storage setup was built because extra space was needed outside the NAS. A cheap backplane from AliExpress was connected to a Lenovo ThinkCentre M920q using an HBA. Several retired hard drives were used for the storage. This is closer to a quick home lab workaround than a polished long-term system. A Synology 1518+ and a Dell OptiPlex 9020 are also part of the same equipment cabinet.
Character Keeper is a self-hosted web app for storing and managing tabletop RPG character sheets. It is meant to work across different game systems instead of being tied to one ruleset. The app is built with React, Node, and JSON. Its maker is not a professional developer and used Claude heavily for design choices and feature work. The feature ideas, product decisions, and testing were still handled by the maker. Security checks have included OWASP ZAP scans and AI-assisted code review focused on login, sharing, and data handling. A stronger security review is still wanted before the app is treated as fully public-ready.
A used network switch bought for $20 is being considered as the starting point for a first home server setup. The plan is to pair it with a Zotac mini PC running Pi-hole for home network ad blocking and DNS control. Most home devices, including a PC, printer, smart TV, and home security DVR, would be connected by Ethernet instead of relying on Wi-Fi. A cheap used business PC, such as a Dell OptiPlex, may be added later to store a DVD collection and run Jellyfin for home media streaming.
AT Protocol work is spreading beyond Bluesky. W Social is one example connected to wider discussion about European digital sovereignty. Lighter alternative front ends such as Red Dwarf are also appearing. For someone running a home server, AT Protocol services could be useful experiments for learning how distributed social tools work. The available information here is more about interest and early exploration than proven setup steps, performance numbers, or long-term hosting results.
The Mac Mini would not be the main computer. It would mainly be used for building apps, testing them, and submitting them to the App Store. A 512GB model is available now, but the extra storage may never be needed. Choosing a 256GB model would save enough money to buy a 1TB external SSD instead. The real choice is whether to pay more for built-in storage now or keep looking for the cheaper 256GB model.
Regular SATA hard drives are expensive in 2026, so used SAS hard drives from retired equipment can be a cheaper way to add storage. One example price is $33 for a 4 terabyte drive. The main problem is that rack trays made for SAS connectors are hard to find. A custom tray was made by changing a common hard drive rack mount design so the SAS connector heads can clip into place. The design took five full-size prints and several smaller test prints to get the connector clips right, and the finished model is available on MakerWorld. The tradeoff is that SAS drives may need an HBA, and the extra power use could reduce the long-term savings.
A small media production team of 3 to 4 people runs three Windows workstations on an air-gapped network. Two machines have DaVinci Resolve Studio installed, and the third runs WSL, RHEL 9, and Docker for Windows to run a photogrammetry program in a container. Moving new software into the isolated network is difficult, so an open-source GitHub release that an automatic scraper can fetch is the most practical path. Licensing is also a constraint, so any added tool needs to be free and not require a separate license. The first need is a self-hosted project management system that can run in a Docker container on the third machine and be used by the other two workstations. Each media project needs fields such as customer, subject, location, event, classification, notes, and attachments. Time tracking and simple metrics would also help show where time is going and which customers have the most finished products. DaVinci Resolve projects currently live in separate local project databases on each workstation.
Checking basic weather is becoming harder in some places. A widely used weather app is blocked behind cookie consent with no clear way to refuse, and there is concern that identity checks may come next. The goal is a simple weather app that can run on a personal server. Several options have been tested, but no working Docker app has been found. The fish906 weather app came close, but it appears outdated because it sends a wrong or slightly changed link in its OpenWeatherMap API call, so it fails. The need is not a complex dashboard, just a reliable way to check the weather from a self-hosted setup.
A simple Docker-based server is already running. The goal is to use the server for Folding@home when it is not busy with other work. Folding@home is a distributed computing project that uses spare computer power from many machines to help with scientific research, including disease-related calculations. The practical question is whether an always-on self-hosted server can safely donate its unused computing power during quiet periods.
