The Dell OptiPlex 7050 SFF is a capable machine for virtualization thanks to its Intel Core i5-7500 processor with built-in virtualization technology. This allows you to consolidate multiple virtual machines (VMs) onto a single physical machine, improving efficiency and resource utilization.
However, the base model's 8GB of RAM might be a bottleneck. Proxmox, a popular virtualization platform, recommends allocating at least 2GB to itself, leaving only 6GB for VMs. This can limit the number and performance of VMs you can run concurrently.
The good news is that the OptiPlex 7050 SFF is designed for upgrades. By adding more RAM, you can significantly enhance its capabilities as a virtualization host. Upgrading RAM is a cost-effective way to breathe new life into the machine and allow you to run more VMs or resource-intensive VMs smoothly.

In this tutorial, we will walk you through upgrading the hard drive, RAM, and network cards in your Dell OptiPlex 7050 Small Form Factor (SFF) desktop. Before we dive in, let's take a quick look at the default configuration of the OptiPlex 7050 SFF.
- CPU: Intel Core i5-7500 3.4GHz 4 Cores
- RAM: 1x 8GB PC4 (DDR4)
- GPU: Intel HD Graphic 630
- HDD: 2.5 Seagate BarraCuda Pro 1TB, 7200 RPM
Note: The Dell OptiPlex 50 SFF Owner's manual is a valuable resource for anyone who owns this small form factor desktop. It contains comprehensive information about the computer's features, specifications, and functionalities.
But more importantly for those looking to upgrade or repair their OptiPlex 50 SFF, the manual provides detailed instructions for disassembly, component identification, and reassembly – making it a handy guide for replacing parts and performing maintenance.
Minimum system requirements for running Proxmox Virtual Environment:
- CPU: Proxmox requires a 64-bit processor with virtualization extensions. This is typically denoted as Intel VT-x or AMD-V on your processor.
- RAM: The minimum RAM requirement is just 1GB, but that's only for the Proxmox software itself. To run virtual machines (VMs) effectively,we'll need additional RAM depending on the resource needs of your VMs.
- Storage: Any hard drive or solid-state drive (SSD) will work for Proxmox installation.
- Network Card: We will need at least one network interface card (NIC) to connect our Proxmox system to the network.
Important Note: These are the minimum requirements for basic evaluation purposes only. For real-world use, especially running multiple VMs, you'll likely need more RAM and storage space.
Proxmox Recommended System Requirements:
- CPU: Intel EMT64 or AMD64 with Intel VT/AMD-V CPU flag.
- RAM : Minimum 2 GB for the OS and Proxmox VE services, plus designated memory for guests. For Ceph and ZFS, additional memory is required; approximately 1GB of memory for every TB of used storage.
- Fast and redundant storage, best results are achieved with SSDs.
- OS storage: Use a hardware RAID with battery protected write cache (“BBU”) or non-RAID with ZFS (optional SSD for ZIL).
- VM storage: For local storage, use either a hardware RAID with battery backed write cache (BBU) or non-RAID for ZFS and Ceph. Neither ZFS nor Ceph are compatible with a hardware RAID controller. Shared and distributed storage is possible.
- SSDs with Power-Loss-Protection (PLP) are recommended for good performance. Using consumer SSDs is discouraged.
- Redundant (Multi-)Gbit NICs, with additional NICs depending on the preferred storage technology and cluster setup.
- For PCI(e) passthrough the CPU needs to support the VT-d/AMD-d flag.
1. RAM Upgrade
The out-of-box OptiPlex 7050 SFF boasts impressive RAM upgradeability. You can expand the memory up to a whopping 64GB, significantly boosting performance, especially when running multiple virtual machines on Proxmox. As you will see in Figure 3, the motherboard is equipped with 4 DDR4 memory module connectors, giving you plenty of room for expansion.
In our setup, we chose to install 4 x 8GB Micron DDR4-2400MHz SODIMM modules. This is a great option, but keep in mind that it's always recommended to consult your motherboard's manual or use a compatibility tool before purchasing RAM. This ensures you choose modules that work seamlessly with your system.
While DDR4-2400MHz is perfectly suitable for running many virtual machines, consider upgrading to faster RAM if your VMs require intensive memory operations.

2. Network Interface Card (NIC) Upgrade
The out-of-box Dell OptiPlex 7050 SFF comes with a single Intel I219-LM Network Interface Card (NIC). While this might be sufficient for basic Proxmox use, we are aiming for a more advanced network configuration, like running a firewall distro such as OPNsense. That's why we will be installing an additional NIC.
We have chosen a Dual-Port PCIe Gigabit Ethernet Card - Intel 82575&82576 with two RJ45 ports. This is a great choice because it's compatible with multiple operating system (Windows/Windows Server/Linux/FreeBSD/DOS) and includes a low profile bracket perfect for Small Form Factor (SFF) machines like the OptiPlex 7050 SFF. You can see this bracket in Figure 4.
The good news is that our chosen Dual-Port PCIe Gigabit Ethernet Card is a PCIe x1 card. This means it is physically compatible with a wider range of PCIe slots, including x1, x4, x8, and even x16 slots. This ensures easy installation in our OptiPlex 7050 SFF. As you can see in Figure 3, the OptiPlex 7050 SFF has a PCI-e x4 connector (slot 1) which is the perfect fit for your network card.
3. Hard Disk and SSD Disk Upgrade
The out-of-box OptiPlex 7050 SFF comes with a 2.5-inch Seagate ST1000LM049 1TB hard drive, which might be sufficient for basic use. However, for a robust Proxmox setup with multiple VMs, you'll likely need more storage. The good news is that the OptiPlex 7050 SFF motherboard offers two upgrade paths that I took advantage of in my setup:
1. Adding a Second Hard Drive: The motherboard provides 3 SATA ports, allowing you to install an additional 2.5-inch hard drive. This is a cost-effective way to increase storage capacity for your VMs. Simply remove the CD-ROM drive and install a second 1TB hard drive using a 12.7mm SATA 2nd SSD Hard Drive Caddy (like the one showcased in Figure 5).

2. Upgrading to an M.2 SSD: For the ultimate performance boost, we also leveraged the M.2 Slot 3 connector. In our setup, we installed a 2 TB Apacer AS2280Q4 (PCIe 4.0 4x NVMe) TLC SSD (demonstrated in Figure 6 and 7). This M.2 SSD is a fantastic choice for experiencing lightning-fast boot times, application loading, and overall system responsiveness, which is especially beneficial for Proxmox and demanding VMs.

Figure 7 depicts the mounted 2 TB Apacer NVMe SSD (also shown in Figure 6).

By utilizing both a second hard drive and an M.2 SSD, we significantly enhanced the storage capabilities of our OptiPlex 7050 SFF for running Proxmox. This approach provides a balance between cost-effective storage expansion and blazing-fast performance for critical applications.
Conclusion
The Dell OptiPlex 7050 SFF is a versatile machine that can be transformed into a powerful Proxmox host with a few key upgrades. By expanding the RAM, adding a network card, and upgrading the storage, you can create a robust system capable of running multiple virtual machines smoothly.
This guide outlined the upgrade process for RAM, network interface cards (NICs), and storage solutions, including both hard drives (HDDs) and solid-state drives (SSDs). Upgrading to an M.2 SSD offers significant performance improvements, while adding a second HDD provides a cost-effective way to increase storage capacity for your VMs.
