ASUS PN63-S1 Small Form Factor PC Review

ASUS PN63-S1 Pinterest Pin

Gone are the days when I need a large tower system to serve as my day-to-day desktop or as a hypervisor for my home lab. I don’t need space for multiple large disks because I now have a NAS. The CPUs that small-form-factor machines have, and the rise of affordable M.2 NVMe SSDs and SATA 2.5″ SSDs make mini PCs suitable for most home tasks. Intel NUCs are popular choices, but what about other small PCs like the ASUS PN63-S1? I recently got my hands on one. Let’s see how it stacks up.

Outfitting the ASUS PN63-S1 with storage and memory.

This machine was going to replace my 12+-year-old tower running Proxmox. To be able to run a sufficient number of VMs for my environment, I went with 32 GB of Crucial DDR4 3200 Mhz RAM. The beauty of this mini PC is that it has two slots for M.2 NVMe drives (in addition to a 2.5 SATA drive). I like to run the OS on one drive and the VMs off a separate drive and it’s great that they can both be fast storage.

I bought a 250 GB and a 1 TB NVMe Gen4 M.2 Western Digital Black drives to run the OS and VMs, respectively.

Taking apart the ASUS PN63-S1 and installing drives and memory is pretty easy, as you can see in the pics below. You simply loosen the four screws and open the bottom up gently. There is a ribbon connecting the board connected to the base and the main housing. There are two clips at the top that you can use to release the ribbon to make it easier to install the RAM and storage.

The M.2 slot inside the case is Gen4, while the one on the bottom of the case is Gen3.

BTW, I went with the Intel Core™ i5-11300H processor as I didn’t think the i7 would offer much noticeable performance benefit for my use and that allowed me to save a few dollars.

ASUS PN63-S1 in use

I installed Proxmox on this machine without incident. However, I did have to turn on the appropriate virtualization options (VT-x) in the BIOS. It has been running stable for a couple of months. Compared to my Intel NUC, this machine is a little bigger but more powerful and quieter.

The things I like about it:

  • Powerful CPU
  • 2 M.2 slots, with one of them being Gen4
  • 2.5 Gbps Intel Ethernet. I don’t have 2.5 Gbps switches yet, but this device will already be ready
  • It has a good set of ports (HDMI, displayport, USB-C, USB 3.2 ports)
  • Easy to install storage and RAM
  • Quiet

Really, there aren’t any things I don’t like about it, except that it doesn’t use a Gen 12 Intel CPU, but it has more than enough power.

Final thoughts

This is a good addition to my list of small-form-factor Proxmox hardware and it is a great addition to my smart home. A box like this could also serve as my next desktop machine. It compares favorably to similar Intel NUCs and is usually a little less expensive. If you’re looking for a capable mini-PC, this should be on your list.
