Are you looking for the best server for your homelab — one that strikes a balance between cost, performance, and modern features like TPM, UEFI, and secure boot?

In this guide, I’ll walk you through everything that really matters when choosing a homelab server today: from CPU, RAM, and remote management to RAID and firmware/security support. You’ll get clear criteria so you can decide what you need vs what’s “nice to have.”

Then, I’ll show you cost-effective Amazon Renewed server picks — devices I believe are solid value for small-to-medium homelabs, whether you’re using Proxmox, ESXi, Hyper-V, or just running a few VMs or containers.

Editor’s Note: This article was updated to include important considerations around TPM chips and SD card modules when building a home lab server. I also fine-tuned the content for better clarity and aligned it more closely with current virtualization requirements (like Windows 11, UEFI, and secure boot support).

What is a home lab server?

A home lab server is the core component of a personal, non-production environment where tech enthusiasts can experiment with new technologies. This dedicated machine serves as the backbone of your home lab, allowing you to run various operating systems, applications, and tools.

Home lab servers allow you to configure your setup however you like, enabling you to test different scenarios and find optimal configurations. They are an excellent way to gain hands-on experience in system administration, networking, or virtualization without the high costs associated with certification exams or production environments.

The beauty of a home lab server lies in its isolated nature. You can freely experiment with new software and technologies without damaging critical systems, and this safe environment encourages learning and innovation.

Before investing in a home lab server, consider factors like power consumption and its impact on your electricity bills. Despite these considerations, a well-chosen home lab server can be a valuable asset in your tech career toolkit, providing a platform for continuous learning and skill development.

What are the benefits of a home lab?

There are several benefits of having a home lab. Here are a few:

• Hands-on experience: A home lab provides hands-on experience with different technologies. It is a great way to learn new technologies and systems administration skills.
• Testing and development: A home lab can also be used for testing and development. It allows you to try out new technologies and software without worrying about damaging anything critical.
• Career toolkit: A home lab can be valuable to your career toolkit. It allows you to experiment with different configurations and find the best ones. Additionally, it provides hands-on experience with various technologies, which can be helpful in your career.
• A home lab can provide several benefits for VMware admins.
• The ability to study for a certification

With home lab hardware, you can safely try out new technologies, experiment with products, and learn from your failures – all from the comfort of your home.

As Thomas A. Edison said: “I have not failed. I’ve just found 10,000 ways that won’t work.”

Build the best server for homelab: Evaluate these features for a server

OS / Platform — Best Fit Use Case

OS / Platform	Best Fit Use Case
Proxmox VE	You want a hybrid setup: virtual machines + containers, strong community support, and open-source tools. Great if you expect to run mixed workloads, cluster features, or snapshot/backup infrastructure.
VMware ESXi	You need enterprise-grade features, live migration, HA (high availability), and strong vendor support. Good for larger or more complex homelabs where reliability and scale matter.
Hyper-V (Windows Server)	If you’re already heavily invested in Microsoft tools / Active Directory / Windows-centric services, and want integration or certain Windows features, Hyper-V is a strong option.
Windows (bare metal, no hypervisor)	Best for straightforward setups: direct installs of Windows apps, games, or media services. Less overhead than virtualized environments; simpler if you don’t need many isolated VMs.
Linux (bare metal, no hypervisor)	Suited for efficient, lightweight services: Docker, single-purpose apps (media servers, storage, small dev / web services), or if max performance per hardware is a priority.

Tower vs Rack Server: Which Form Factor Is Right for You?

If you want quiet, flexible placement and easier maintenance (especially near living or office space), a tower server is usually the better pick. If you anticipate expanding, prefer efficient space utilization, or already have a rack setup, then opting for a rack server may offer better scalability and organization.

Form Factor	Best Fit Use Cases
Tower Server	Small setup, living room or home office; limited rack infrastructure; low noise important; moderate expansion; easier access for upgrades.
Rack-Mounted Server	More servers or hardware already in a rack; need for high-density; planned expansion; desire for centralized cabling, cooling, and clean airflow; possibly multiple chassis or units.

CPU / Processor — What Matters and What You Can Skip

Consideration	Best Fit / What to Look For
Mid-range CPU instead of “monster cores”	If you’ll run 2-5 VMs, some containers, or services like media servers / NAS, you don’t need top-end CPUs. A mid-range (e.g. 4-8 core Xeon / Ryzen / Intel server grade) often performs well while saving cost and power.
Energy efficiency	If the budget is limited, put more cost into RAM, storage (fast & reliable), and good SSDs rather than overspending on the CPU. A balanced setup often beats a CPU-heavy but weak RAM / storage system.
Budget priorities	If the budget is limited, allocate more resources to RAM, storage (fast & reliable), and good SSDs rather than overspending on the CPU. A balanced setup often beats a CPU-heavy but weak RAM / storage system.
Upgrade path	Choose a motherboard / platform that allows CPU upgrades later. Optionally dual CPU support, or spare CPU socket / compatible chipsets helps future expansion. Also consider that renewed server CPU/parts might have limitations (older generations, less headroom).
Bare metal vs VM/Hypervisor vs no virtualization	Look at TDP, power draw at idle, ability to use power/sleep / CPU C-states. Lower power CPUs can save a lot over time, especially if running 24/7.

As you know, all manufacturers offer remote management. Dell calls it iDRAC, HP calls it iLO, and Supermicro calls it IPMI.

Features like accessing the BIOS are already included in the basic configuration for all servers. I recommend updating for iDRAC Enterprise (Dell). It will offer complete remote management, including login to the hypervisor. The enterprise package also provides the ability to monitor email notifications. It is worth the cost, even in a home lab environment.

The same applies to HP iLO; every ProLiant server comes with iLO, but the Advanced Pack offers more features, such as notifications and guest server remote control.

The Supermicro IPMI interface is acceptable, and the Java requirements have been eliminated; however, Dell and HP offer significantly better interfaces.

Feature / Capability	Why It Matters (When It’s Helpful)
Power control (on/off/reboot)	Great for when the OS is hung or during power cuts; no need to walk to the server.
Out-of-band console / Virtual KVM	Let’s you see the boot process, BIOS/UEFI settings, or install OS as if you were locally connected. Helpful especially with headless servers or when installing remotely.
Firmware / BIOS access / Virtual Media	Ability to mount ISO or drive remotely saves effort; helps with firmware updates, patching. But often requires licensing with vendor tools.
Sensor/health monitoring (temps, fans, voltage, logs)	Early warning for overheating, failing fans/PSUs. Helps maintain server health and plan upgrades.
Secure remote access + licensing	Sensor/health monitoring (temps, fans, voltage, logs)

RAID controller with a few HDs

A RAID controller is a device that helps manage your computer’s storage and can boost its performance. It can create a storage array, a group of drives that work together to improve data security or increase storage capacity.

I recommend getting a RAID controller for your home lab server. The performance boost and the extra features are worth the cost. For example, some RAID controllers offer a cache, which can improve your server’s performance.

Dell PowerEdge or HP Proliant server already has a RAID controller on the mainboard, which is sufficient for home lab use.

I prefer a combination of SSD, NVMe, and SAS/SATA drives in a RAID 1 and RAID 5 configuration. It strikes a good balance between performance/cost.

If you plan to use Proxmox with the ZFS file system, hardware RAID configurations are not the best choice; instead, opt for an HBA only. The Proxmox operating system will see all HDs, and you can configure them for ZFS.

See my article RAID Controller Explained: What You Need to Know.

TPM Chip (Trusted Platform Module)

A TPM chip adds a critical layer of hardware-based security to your home lab server. It enables features like data encryption, secure boot, and measured boot, making it a highly recommended component for any modern server setup.

If you’re planning to run Windows 11 virtual machines, keep in mind that Microsoft requires TPM 2.0 and UEFI firmware. Both Proxmox and VMware ESXi support virtual TPM passthrough; however, your physical server must have a TPM module to utilize this feature securely.

SD Modul (memory card)

Many systems come equipped with slots for SD memory cards, offering a convenient option for installing lightweight virtualization hypervisors, such as ESXi or Proxmox. Installing the hypervisor on an SD card can free up your main drives for data storage, helping optimize overall system efficiency.

In my setup, I run ESXi on a dual SD card module, which provides an additional layer of redundancy.

That said, some argue that using SD cards for hypervisor installations is risky because SD modules tend to wear out faster than hard drives or SSDs, especially with constant read/write operations. I think it’s still a valid option, but only if you use high-quality, industrial-grade SD cards and preferably a mirrored setup for extra resilience.

Noise

When purchasing a server, consider its noise level. Based on my experience with Dell PowerEdge and HP ProLiant servers, noise is typically not a significant issue, especially with newer tower models. However, Supermicro servers can still be quite loud and may not be suitable for shared spaces.

Warranty

When investing in a home server, I always opt for a five-year next-business-day warranty package, which aligns with my typical upgrade cycle. By operating a mail server with Exchange 2019 at home, this warranty provides quick repairs and peace of mind.

Compatibility Across Use Cases	In many cases, these servers work well for Proxmox, ESXi, media servers, Home Assistant, Minecraft/game servers, and Windows or Linux bare-metal setups—as long as you check hardware compatibility (drivers, firmware) first.

I recommend Dell, HP, or Supermicro servers. I’m not a fan of Lenovo servers.

Dell Servers

Dell’s PowerEdge servers are another excellent choice, especially if you have specific use cases. They come with Intel Xeon processors and are super user-friendly. Customizing is a breeze; they even have a built-in RAID controller called PERC. There is no need for a separate one unless you have special requirements. Plus, they offer various bay options to fit your storage needs. I highly recommend PowerEdge for anyone setting up a server environment.

HP Servers

HP’s Proliant servers are a top pick for many, and the Proliant 380 or 360 Gen9/10 is a versatile server that stands out. It’s fast, easy to tweak, and has built-in tools like smart array controllers for storage and basic ILO for remote management. Want more features? You can upgrade the ILO anytime.

Amazon has great deals on renewed Proliant servers, making it even more budget-friendly.

Supermicro Servers

Supermicro servers are a budget-friendly pick but come with a few caveats. They’re noisier, so think twice about setting them up in a quiet space. The user interface isn’t as slick as that of HP and Dell, and their management features aren’t as robust. However, they do have basic remote management through IPMI.

If you go for Supermicro, consider getting a separate Mega RAID adapter card to boost its capabilities.
