Welcome back to Andysworld! — where homelab dreams come to life, one project at a time.
In Part 3 of our Minisforum MS-A2 Series, we’re diving into the ultimate upgrade combo: installing a high-speed NVMe SSD and setting up Windows 11 on this tiny powerhouse. If you’ve been following along, you already know we’ve upgraded the hardware and reconfigured the internals — now it’s time to breathe life into it.
Why the MS-A2 Deserves NVMe + Windows 11
The Minisforum MS-A2 continues to impress with its powerful Ryzen APU, dual-channel DDR5 support, and surprisingly modular design. But to unlock its true potential in a modern homelab, we need:
? Fast, reliable storage (via NVMe SSD) ? A clean, up-to-date OS install (Windows 11 Pro FTW) ? Flexibility for running VMs, containers, or lab workloads
Step 1: Installing the NVMe SSD
Whether you’re using the primary M.2 NVMe slot or (as we showed in Part 2) the secondary A+E Key slot, here’s how we did it:
Power off the device and remove the bottom panel.
Insert the Samsung NVMe SSD into the M.2 slot.
Secure it with the retaining screw.
(Optional) Add a heat sink or thermal pad if you’re planning to run it hard.
Reassemble and power up!
? Confirmed: BIOS detected the SSD on first boot — no drama.
Step 2: Installing Windows 11
Now that we’ve got our drive ready, let’s get Windows 11 installed:
Boot the MS-A2 and hit DEL or F7 to enter the BIOS/boot menu.
Select the USB installer and follow the prompts.
Choose custom install and select your NVMe SSD.
Complete the install and apply your license key or link your Microsoft account.
? Tip: Disable TPM and Secure Boot in the BIOS if you encounter issues — though the MS-A2 should support them natively.
First Boot – Lightning Fast!
Windows 11 boots in under 10 seconds thanks to the NVMe SSD. With DDR5 and Ryzen onboard, the desktop is snappy and responsive — ideal for:
Hyper-V, WSL2, or VMware Workstation
Remote Desktop Gateway
Lightweight game streaming or media server
Home automation or dev work
Final Thoughts: A Tiny Titan for the #homelab
The Minisforum MS-A2 is proving itself as a top-tier mini PC for lab use, and this Part 3 upgrade cements its place in Andysworld!’s go-to toolkit.
Whether you’re deploying Windows, Linux, Proxmox, or VMware, getting fast local storage and a clean OS install is the foundation of a great setup — and this one ticks all the boxes.

In today’s hardware deep-dive, we’re making a bold swap inside the Minisforum MS-A2 mini workstation — removing the built-in Wi-Fi/Bluetooth card and replacing it with an NVMe M.2 SSD using the A+E Key slot. Yes, that’s right: we’re trading wireless convenience for high-speed storage, and it’s a swap that may surprise you with how useful it can be.
Why Replace the Wi-Fi Card?
For most users, the built-in wireless is more than enough. But in a lab environment, edge deployment, or media server use case, you may not need Wi-Fi at all — especially if you’re running on wired Ethernet.
Instead, using that M.2 A+E Key slot to install an NVMe SSD can:
Expand fast local storage
Speed up data access for virtual machines or containers
Offer better thermal performance than using external drives
And that’s exactly what we did.
The Upgrade in Action
Check out the image above, where the former Wi-Fi card once sat — it’s now replaced with a slick Samsung NVMe drive, mounted directly into the A+E Key slot. The process was straightforward:
How We Did It:
Power off and open the MS-A2 case.
Carefully disconnect the Wi-Fi antenna leads and remove the wireless card secured by a single screw.
Insert your NVMe M.2 SSD (compatible with A+E Key) into the same slot.
Screw it down.
Boot into BIOS or OS to verify the drive is detected.
No adapters, no BIOS hacks — it just works!
What to Watch Out For
Compatibility: The A+E key slot must support PCIe lanes for NVMe. Some devices may restrict use to Wi-Fi cards only.
Boot Support: Not all systems support booting from drives in this slot, so we’re using it strictly for additional storage.
Thermals: NVMe drives can get warm. If you’re using it heavily, consider a heat spreader like we’ve installed.
Final Thoughts from Andysworld!
This swap is a brilliant use of underutilized hardware real estate. If you’ve hard-wired your Minisforum MS-A2 and don’t need the wireless module, this is a clever hack to expand your high-speed storage without touching your main NVMe slot.
Let me know in the comments if you’ve done a similar mod or if you want help checking whether your own mini-PC supports this trick.

Welcome back to another episode of Hancock’s VMware Half Hour! In this video, we take you step-by-step through updating the UEFI BIOS on the Minisforum MS-A2, upgrading from version 1.0.1 to 1.0.2 – all from a very hot #homelab (35°C!).
We walk through downloading the BIOS update, prepping the system (disabling Secure Boot), launching the UEFI shell, and flashing the firmware using EfiFlash.nsh. There’s even a little pop culture nod to Toto and The Wizard of Oz ??, plus a shout-out to VMware vExperts like Daniel Kreiger, William Lam, and Stephen Wagner!

If you’ve followed Andysworld.org for any length of time, you’ll know I’m always on the lookout for compact, powerful systems that pack a serious punch — especially for virtualization, homelab testing, and edge computing. The Minisforum MS-A2 just landed on my desk, and I couldn’t wait to tear into it, max out the RAM, and see how this tiny monster performs.
Why the Minisforum MS-A2?
Minisforum has carved out a strong niche in the mini PC market, but the MS-A2 is something different. Designed around the AMD Ryzen 9 9955HX (a 16-core, 32-thread beast), this unit is built for power users: developers, sysadmins, content creators, and homelab enthusiasts like myself.
The MS-A2 offers:
AMD Ryzen 9 9955HX (Zen 4, 5nm, 16C/32T)
Up to 128GB DDR5 SODIMM RAM
Quadruple PCIe Gen4 NVMe M.2 slots
Dual 2.5G Ethernet, Dual 10G SFP+
USB 4.0 / HDMI 2.1 / USB-C
Compact footprint with surprisingly good thermals
With specs like that, it’s an ideal candidate for running Proxmox, VMware ESXi, KVM, or even just as a hyper-efficient workstation.
The Unboxing Experience
Right out of the box, the MS-A2 gives off a premium vibe. The packaging is minimalist but well thought out. Inside you’ll find:
The MS-A2 unit itself (dense, solid, well-built)
120W or 180W power adapter (depending on config)
Mounting hardware
User manual and warranty information
Ports are plentiful and logically laid out. It even includes USB 4.0 and dual LAN ports — a must for virtualized networking setups in a homelab.
Installing 128GB DDR5 RAM
This is where things get exciting.
The MS-A2 officially supports up to 128GB of DDR5 SODIMM RAM (2x 64GB modules). While 64GB used to be the ceiling for mini PCs, the MS-A2 pushes those boundaries.
Here’s how I installed the RAM:
Power Down and Open the Chassis: Remove the bottom screws (Torx) and gently lift the cover. The internals are neatly laid out.
Locate the SODIMM Slots: There are two DDR5 SODIMM slots accessible without needing to remove any other components.
Install 2x 64GB DDR5 4800MHz Modules: I used Kingston DDR5 SODIMMs — click, click, done.
Reassemble and Boot: Replace the cover, screw it down, plug it in, and power on.
Check BIOS/UEFI: The system immediately recognised the full 128GB RAM without issue.
Initial Impressions & Performance Potential
I haven’t fully benchmarked it yet, but early signs are strong. This thing is built for virtualization and power-intensive workflows. With 128GB RAM, you could comfortably run:
Nested vSphere or ESXi environments
A full Proxmox VE cluster in one box
Multiple Linux and Windows VMs for testing
Container platforms like Docker, Podman, or Kubernetes
The dual 2.5G NICs are ideal for setting up a virtualized network or using VLANs for isolated testing.
Thermals remained under control during initial tests, thanks to the robust cooling design. The unit is quieter than expected even under moderate load.
Who Is the MS-A2 For?
If you’re:
A homelab enthusiast looking to consolidate noisy, aging servers
A virtualization geek building a portable test lab
A developer or DevOps engineer running VMs or containers
Or just someone wanting a high-end mini PC that doesn’t take up half a desk…
…the MS-A2 is absolutely worth your consideration.
What’s Next?
In the next blog post, I’ll benchmark this machine with:
Proxmox VE running multiple VMs
VMware ESXi 8.0 (yes, it installs!)
Synthetic CPU, disk, and memory benchmarks
Power draw and thermal tests
And maybe even try some GPU passthrough.
Final Thoughts
The Minisforum MS-A2 is a seriously impressive piece of kit. It proves that small doesn’t have to mean slow or limited. With 128GB DDR5 RAM, Ryzen 9 power, and robust I/O, it’s more than capable of replacing a rackmount server for many use cases — and it’ll fit in your backpack.
Stay tuned for more testing, benchmarks, and homelab setup tips.
