DeskMeet B660 Review Part 1: As a development virtual environment

(This article is a review of the AsRock DeskMeet B660)

I am a big fan of small PCs, and I am very grateful for them, living in a small house in Tokyo, Japan.

It's a barebone style of motherboard + power supply + case.

  • PCIe card (2 slots) can be installed in a very small 8L case
  • Four DDR4 memory slots
  • Can be loaded with 3.5″ HDD, 2.5″ HDD/SSD, etc. quite a bit.
  • 500W power supply included

By the way, some people say it's “big” compared to DeskMini, but I personally think it's “MINI”.
Personally, I felt that it's just like this as a mini-itx case, and the lack of depth makes it feel less oppressive than you might expect.

The accessories are as follows.

memory slot

The motherboard is mini-itx sized, but
One of the advantages of DeskMeet is that it has four memory slots.

As you know, a normal mini-itx motherboard has two memory slots.
If you want to put 64GB of memory and insert 32GB DDR5*2, you will have to spend a lot of money, even though the price is lower. On the other hand, DeskMeet has 4 slots and DDR4, so you can add more memory at a reasonable price.


One PCIe slot is provided. Normally, a graphics card would be inserted in this slot.
If you like, you can put other cards, such as NICs.

Other terminals

Front: Audio jack, USB-C port, USB 3.2 Gen1 Type-A2, USB 2.0 Type-A2
Rear: 3 video jacks (DP/HDMI/D-Sub), RJ-45 (1Gbps Intel), USB 2.02, USB 3.2 Gen1 Type-A2, audio jacks

Smaller models (DeskMini X300, etc.) lacked a USB port, but this is all you need.
I appreciate the fact that it has an Intel NIC, but I would have preferred 2.5G if I wanted…

Using DeskMeet as a base machine for virtual environments

Main topic.

VMs are currently used for various purposes including application development. I also use a “VM on NAS” when I want to experiment, but… it's too slow.

If possible, I want to use a machine that can handle a large amount of memory with the latest CPU.
I want a machine that can handle a lot of memory, and I want it to be small and affordable.

DeskMeet is the only way.

Sorry to those of you who were hoping for a gaming DeskMeet. I hope to do a review in that direction someday…

As for the E-cores on Alder Lake, I've seen information that they are not recognized by VMware ESXi (disable E-cores or else it won't boot?). The highest number of P-cores is… 12900(K)/12700(K) with 8 cores. But I have a rationale that I don't want to put that in a chassis like this. Therefore, I chose the intel core-i5 12400 (6 P-cores), which seemed to be well-balanced. I chose a model with built-in graphics.

By the way, because I am a Noctua believer, the CPU cooler is Noctua.

Please see our other article for a discussion of CPU coolers.

In a virtual environment, there is no need to have too much memory.
Let's take advantage of the fact that there are 4 slots and use the most powerful configuration, “32GB*4=128GB“!


since it is a barebone, all you have to do is attach the parts.

The layout is well thought out. The fan of the power supply is facing the opposite direction from usual (sucking fresh air from the outside) to hit the CPU, which is bizarre but makes sense. Well, as the load on the power supply increases, the air temperature is likely to increase, but since it is 500W, the temperature will not be that high….

NIC” for PCIe slots.

Since I want to make this machine suitable for virtual development environment, I will install Intel's 2.5Gbps NIC I225-T1 in the PCIe slot, not a graphics card, to compensate for the non-powerful on-board. I don't want to waste my time on ESXi (with Intel chip, I don't have to worry about drivers).

Since it is not a graphics card, it occupies only one slot (and a short one at that), so it is a space-saver. To improve airflow, we decided to add a 120mm fan to exhaust air from the top.


The procedure is as follows. The following site was used as a reference.

Performance on ESXi varies depending on the configuration, but for reference, here are the results of running Cinebench R23 under the following conditions.

  • core i5 12400
  • used 8 vCPUs (since this is the free version of ESXi),
  • no utilization limits, etc.
  • 32GB memory allocation
  • Windows 10 Pro

Score is 10091.(12400 used with 8 threads)

I tried AsRock's “DeskMeet B660” for “virtual environment” use, and it was more comfortable than expected.


  • 8 liter size, equipped with PCIe slots.
  • Four memory slots, XMP readable
  • Includes power supply, CPU, memory, storage, OS, etc. You can have a very small and extreme machine without worrying
  • 3.5″ HDD can be installed.
  • Onboard NIC made by intel

regrettable point

  • The onboard NIC is 1Gbps, which is somewhat slow nowadays

It is really amazing that there are almost no blind spots.
It will be fun to make it into a gaming PC, too. (The end)

  • Hi Mak,
    I am interestinf to read your posts. I also want to buy the ASRock Deskmeet B660 and install ESXi. Can I use the default esxi image to install on B660? If I use M2 SSD and default NIC intel 219V, do I need to re-image the ESXi image? I am looking forward your reply. Thank you very much.

    • Hi Allen,
      (try using deepl or google translate)

      It is written in Japanese, but I worked from this page.

      I worked as described in the above page and re-imaged ESXi.

      From reading your comment,
      you are using the default NIC, so unless your SSD is quite special, you may be able to boot with the default ESXi image.
      BTW, I used ESXi 7.0.3, so I don’t know about the behavior of the latest version. Sorry.

      I wish you good results.
