Stop buying mini PCs for your home server—5 reasons an old Dell OptiPlex actually wins


A mini PC is a solid option for a home server. They’re small, relatively cheap, and low-power. I use a mini PC as a home server, but there are several things that my old Dell OptiPlex PC does better.

I Won’t Buy a Mini PC for Plex Without These 4 Features

Any old mini PC will work, but I’ve got my preferences.

Storage expansion

A home server is all about storage, and at first glance, my Beelink Mini S12 Pro and Dell OptiPlex 9020 SFF look fairly similar in terms of internal storage options. The big difference is the type of storage each system can take.

My mini PC is limited to M.2 drives and small 2.5-inch drives. While 2.5-inch HDDs exist, they’re far more expensive per gigabyte and max out at a lower capacity.

In comparison, my Dell OptiPlex 9020 SFF has one 3.5-inch SATA drive bay and two 2.5-inch bays. It means my OptiPlex can support a full 3.5-inch mechanical drive. I could buy an 8TB HDD for a fraction of the cost of an equivalent 2.5-inch drive.

There’s also an optical drive bay that can be repurposed with a caddy. This means I can fit both a large HDD and 2.5-inch SSDs to get the best of both worlds. For services that need bulk storage, such as Plex or Nextcloud, that cheap HDD storage can be very useful.

PCIe slots

My mini PC is also lacking any additional PCIe slots. What you buy is what you get; there’s no internal PCIe expansion for adding a graphics card, network card, capture card, or an adapter for extra storage. The possibilities to expand the mini PC beyond its current capabilities are therefore limited.

In comparison, my Dell OptiPlex has a low-profile PCIe x16 slot and a PCIe x4 slot. The first slot is ideal for a low-profile graphics card, which can help with hardware transcoding or other GPU-accelerated tasks.

The second slot can then be used for options such as a faster network adapter or an M.2 NVMe adapter so that I can not only add more storage, but that secondary storage can be much faster than SATA, too.

Repairability

Another challenge with a mini PC is that it’s far less repairable. If something goes wrong with my mini PC, repairing it may be a challenge. With my OptiPlex, the parts are reasonably easy to source and not too expensive to buy. The OptiPlex 9020 SFF uses a proprietary Dell PSU, but these machines are so common that you can usually find a replacement on eBay that won’t break the bank.

The CPU on my mini PC is soldered to the board, so if it dies, so does my machine. With the OptiPlex, you can replace or upgrade the CPU if necessary without having to replace the whole PC. These OptiPlex PCs were designed for businesses, so they were made with repairs in mind.

Upgradeable RAM

Room for more if you start with too little

When I bought my mini PC, I opted for 16GB of RAM, which was the highest available option. I knew that once I made my purchase, that was it. I wasn’t going to be able to upgrade the RAM, as the Beelink Mini S12 Pro only officially supports 16GB; if I wanted more RAM, I’d have to buy a new device.

My OptiPlex came with 16GB of RAM, too, but unlike the mini PC, it has 4 DIMM slots and can take up to 32GB of RAM. That meant that when I wanted to add more RAM, it was quick and easy to do. Instead of having to buy a whole new machine, I just needed to buy some more RAM and install it for an instant upgrade.

Thermals and cooling

A better option to run all day and night

This is something that I’ve had issues with in the past with my mini PC. It runs cool at idle and can handle a reasonable amount without breaking too much of a sweat. Under heavy load, however, the small chassis and minimal cooling mean that it can start to throttle.

I’ve even had occasions where the mini PC has shut down because it got too hot, and I’ve had to wait for it to cool down before I could start it up again. This isn’t ideal for a home server that you want to run 24/7.

In comparison, the OptiPlex was built to run at least eight hours a day in offices under heavy workloads. It has a dedicated CPU heatsink and a chassis fan with front-to-back airflow, all designed for sustained operation. It can handle sustained load much more capably than my mini PC can, although the trade-off is that it uses more power.


Sometimes bigger is better

A mini PC is a solid option for a home server if you’re not planning to run every service under the sun, but an SFF PC also has a lot to offer. You can often find a used SFF OptiPlex PC online for less than the price of a new mini PC. Ultimately, I ended up running both, putting each service on the most suitable machine for its needs.

Google Maps has a long list of hidden (and sometimes, just underrated) features that help you navigate seamlessly. But I was not a big fan of using Google Maps for walking: that is, until I started using the right set of features that helped me navigate better.

Add layers to your map

See more information on the screen

Layers are an incredibly useful yet underrated feature that can be utilized for all modes of transport. These help add more details to your map beyond the default view, so you can plan your journey better.

To use layers, open your Google Maps app (Android, iPhone). Tap the layer icon on the upper right side (under your profile picture and nearby attractions options). You can switch your map type from default to satellite or terrain, and overlay your map with details, such as traffic, transit, biking, street view (perfect for walking), and 3D (Android)/raised buildings (iPhone) (for buildings). To turn off map details, go back to Layers and tap again on the details you want to disable.

In particular, adding a street view and 3D/raised buildings layer can help you gauge the terrain and get more information about the landscape, so you can avoid tricky paths and discover shortcuts.

Set up Live View

Just hold up your phone

A feature that can help you set out on walks with good navigation is Google Maps’ Live View. This lets you use augmented reality (AR) technology to see real-time navigation: beyond the directions you see on your map, you are able to see directions in your live view through your camera, overlaying instructions with your real view. This feature is very useful for travel and new areas, since it gives you navigational insights for walking that go beyond a 2D map.

To use Live View, search for a location on Google Maps, then tap “Directions.” Once the route appears, tap “Walk,” then tap “Live View” in the navigation options. You will be prompted to point your camera at things like buildings, stores, and signs around you, so Google Maps can analyze your surroundings and give you accurate directions.

Download maps offline

Google Maps without an internet connection

Whether you’re on a hiking trip in a low-connectivity area or want offline maps for your favorite walking destinations, having specific map routes downloaded can be a great help. Google Maps lets you download maps to your device while you’re connected to Wi-Fi or mobile data, and use them when your device is offline.

For Android, open Google Maps and search for a specific place or location. In the placesheet, swipe right, then tap More > Download offline map > Download. For iPhone, search for a location on Google Maps, then, at the bottom of your screen, tap the name or address of the place. Tap More > Download offline map > Download.

After you download an area, use Google Maps as you normally would. If you go offline, your offline maps will guide you to your destination as long as the entire route is within the offline map.

Enable Detailed Voice Guidance

Get better instructions

Voice guidance is a basic yet powerful navigation tool that can come in handy during walks in unfamiliar locations and can be used to ensure your journey is on the right path. To ensure guidance audio is enabled, go to your Google Maps profile (upper right corner), then tap Settings > Navigation > Sound and Voice. Here, tap “Unmute” on “Guidance Audio.”

Apart from this, you can also use Google Assistant to help you along your journey, asking questions about your destination, nearby sights, detours, additional stops, etc. To use this feature on iPhone, map a walking route to a destination, then tap the mic icon in the upper-right corner. For Android, you can also say “Hey Google” after mapping your destination to activate the assistant.

Voice guidance is handy for both new and old places, like when you’re running errands and need to navigate hands-free.

Add multiple stops

Keep your trip going

If you walk regularly to run errands, Google Maps has a simple yet effective feature that can help you plan your route in a better way. With Maps’ multiple stop feature, you can add several stops between your current and final destination to minimize any wasted time and unnecessary detours.

To add multiple stops on Google Maps, search for a destination, then tap “Directions.” Select the walking option, then click the three dots on top (next to “Your Location”), and tap “Edit Stops.” You can now add a stop by searching for it and tapping “Add Stop,” and swap the stops at your convenience. Repeat this process by tapping “Add Stops” until your route is complete, then tap “Start” to begin your journey.

You can add up to ten stops in a single route on both mobile and desktop, and use the journey for multiple modes (walking, driving, and cycling) except public transport and flights. I find this Google Maps feature to be an essential tool for travel to walkable cities, especially when I’m planning a route I am unfamiliar with.


More to discover

A new feature to keep an eye out for, especially if you use Google Maps for walking and cycling, is Google’s Gemini boost, which will allow you to navigate hands-free and get real-time information about your journey. This feature has been rolling out for both Android and iOS users.
