5 of the best upgrades for your home server PC

Let’s say you managed to grab a server PC for your home lab and equip it with the best operating system for your experiments. While the system may surpass your expectations in the beginning, you might realize that it doesn’t hit its full potential after using it for a while. Perhaps it lacks enough ports and connections for your USB passthrough needs. Or maybe the system doesn’t possess enough horsepower to transcode your favorite 4K movies without running into performance issues.

That’s your cue to add some extra components to your workstation. As an avid collector of server hardware, here are my recommendations for the best upgrades you can make to your home server PC.

ECC memory

Bit-rot, begone!

Home servers can double as amazing backup, file-sharing, and archival hubs. But as you continue storing data on your makeshift NAS, your memory can get corrupted due to a handful of physical (and even software) factors. In the worst-case scenario, these corruptions (called bit rot) can render your precious data unusable.

Error Correction Code (ECC) memory featuring redundant bits per byte can automatically correct bit rot issues and save the rest of the memory from getting corrupted by serious hardware faults by disabling the affected memory stick. The only other caveat besides the higher price tags on ECC memory sticks is that you’ll need a motherboard compatible with these modules, which is why it ranks so low in this article.

Graphics cards

Low-profile cards for basic tasks, pricey GPUs for AI/gaming experiments

Although graphics cards are typically associated with gaming PCs, they’re quite useful for home lab projects. For instance, pairing your GPU with a Frigate/ZoneMinder surveillance system can enhance its object recognition and motion detection capabilities. Likewise, if you’re using your home server to host media servers, a GPU can prevent performance hiccups during heavy transcoding workloads.

Then you’ve got more advanced workloads, such as locally-hosted LLMs and image generators, which can benefit tremendously with a high-end GPU. So long as you’ve got a decent processor, you can leverage GPU passthrough to turn your workstation into a remote game streaming server.

Storage drives

The more, the merrier

Deploying a fleet of virtual machines and containers never stops being fun, but you could end up choking the LVM drive of your virtualization platform if you’re not careful. And the situation gets far worse once you factor in the different virtual guest templates, snapshots, and ISO files you’re bound to store on a server.

As such, it never hurts to grab some extra storage drives. You could use the drives as LVM disks, media repositories, NVR storage, or even create RAID setups for better redundancy.

PCIe adapter cards

Ports galore

While we’re on the subject of drives, it’s just as easy to run out of SATA and NVMe ports when you’re slotting multiple disks into your home server. Likewise, your motherboard may not include enough ports if you want to pass through USB devices to all your virtual guests.

That’s where PCIe adapters and expansion cards come in handy by letting you increase the I/O ports on your home server. Plus, many of these cards are fairly inexpensive, so you don’t have to worry about spending hundreds of dollars upgrading your server.

Network Interface Cards

For blazing-fast transfer speeds

1 Gigabit Ethernet may suffice for casual consumer-grade devices, but it’s far from ideal when you seek to run a hardcore home lab. The 125 MB/s transfer speeds can bottleneck NAS workloads involving SSDs and/or higher RAID levels. Once you start getting into cluster setups, you’re going to need at least 2.5GbE to avoid terribly low speeds when migrating VMs.

Interfacing a faster NIC can boost the network performance of your home server, and you can even go for a card with multiple Ethernet ports to utilize link aggregation technology. That said, you should be prepared to shell out even more on a switch that can handle the faster connection.

There’s no shortage of home lab devices

Aside from the components you can slot into your server, there are tons of devices that can enhance the functionality of your entire home lab. For instance, a UPS can ensure your home server, router, switch, and essential devices remain operational during blackouts. A rack can also go a long way in making your workspace look organized. If you work with too many virtual machines, I also recommend investing in another mini-PC, as it can act as a spare backup server in case your experiments render your main workstation unusable.
