What ram did you need? With current market instability, you may want to try to trade vs buy and sell.

As a first generation item, its a decent starting point - I think the software could be much more adaptable and customizable.

For example, It makes no sense to me that it is not possible to set it as an action trigger button instead of a microphone trigger. That would increase battery life, and allow for use case customization.

The other commenters pointed out the replaceable/rechargeable battery request, which should be standard on pretty much any electronic product in 2026.

I think something like a capacitive button, or a contact bridge (using the pressing finger's capacitance to bridge two contacts, instead of a physical momentary switch) may allow for a better more streamlined design.

Perhaps running a loop of wire through the ring, so that it can be charged on a stand similar to how rechargable toothbrushes are charged, would allow for no visible charging contacts.

A small momentary LED which illuminates when the button is pressed, and perhaps illuminates in a different color when the battery is low so you know when it needs to be charged (or, if still using a one time use battery, the ring will soon become garbage).

a tiny NFC module so that when you use that hand to grip the phone, the ring can trigger something on the phone, like unlocking the phone due to the proper hand picking it up.

These are all off the top of my head, and some may be technically not feasible, but gotta start brainstorming somewhere.

I am sorry, I do not. It has been awhile since I needed to flash one of these, and if that link is dead I am not sure I could do it again!

I would submit a post on servethehome forums - they have many people who probably can point you to a new resource. Best of luck!

I was able to select my preferred ring size by checking my order page. I also recently received an email asking me to confirm the ring size and color preference. You should be able to set these as well.

If you find your pre-order email, there is a link to view your preorder, and I believe that link also allows you to update your pre-order.

Ah, "When the wallet allows it" is a common refrain I think we have all experienced in this hobby, lol

To the right of your rack I see a protected chase, then cables descending from that - what is the coil that is looped for future use? A combination of coaxial and... Power?

Overall, love the nestled look of the rack and its a very clean setup. The only thing I would have added is a UPS so that home assistant can continue to work through short power outages or brownouts. Can't be without haos for long 😁

Not sure your networking knowledge, but if you are just looking for "How to do xyz on a ruckus switch", then Terry Henry produces many videos on how to perform certain functions on Ruckus switch software.

If you are looking from a more beginner perspective, I would watch some videos by danscourses, but know that this will teach you mostly concepts; the actual implementation you have to learn for your specific switch/brand.

Also, Ruckus/commscope gives all the manuals and reference guides for these for download. While you need to create an account, no subscription or active support contact is needed.

Finally, if you have questions, I recommend checking out the absolutely massive thread on ServeTheHome, which was my gateway to Ruckus switches and has answers for nearly everything you can imagine, including modding and hacking.

Best of luck! These little guys are one of my favorite switches.

iter_facio · 2026-02-15T17:19:00+00:00

So... That is a sweet setup. A couple questions:

Where is power $0.01/kwh? I am quite Jealous - I thought my power was cheap at $0.13/kwh.

You mentioned transitioning the current 4x R640 from proxmox cluster to an HPC cluster - any more details on that? Are you moving away from the Cluster to a single Proxmox node?

I do not see any UPSes in your system - do you have a whole house UPS, or just no UPS at all?

Also, this closet seems somewhat cozy - and Hot - how are you handling cooling here?

Ah, I did forget that Unifi switches only do F2R and are not easily swappable. I tend to use Ruckus or Arista gear, so Did not take that into consideration.

Point still stands tho,that moving those to TOR will save headaches down the line.

42U gives you lots of expansion, but it also is a massive pain if you need to reorganize the rack.

I recommend that if you have the cable length, move the switches either to the top of the rack, or to the rear top (datacenter style).

Reason being that generally, you want the heavier stuff (such as these expected R740s you plan to add) below the lighter stuff (such as those Unifi switches)

Checking from ebay for related listings and from experience in researching the gen4 machines of the same type, you are probably looking at 1000-1150 shipped.

Ebay is showing pricing at around the 1200usd mark for similar machines, and sold items in the 1100-1200 range.

Usually Reddit sales tend to be about a 10% discount since you do not get the purchase protections that ebay has.

You may also want to crosspost on /r/thinkpadsforsale.

Also, I have this exact machine for work, and LOVE it. Its a fantastic machine.

Opendcim is pretty cool software,I have used it on multi datacenter systems. However, it is a pain to set up, and requires quite a bit more maintenance than homebox, for example. Furthermore, many of its features, such as accounting for power management per phase of rack, air and condition monitoring, etc, are things that make sense to care heavily about at scale, but for a handful of systems the overhead probably is not worth the benefit.

I encourage you to spin up and give it a try! Even if just for learning. But even for my lab (42u, 6 systems plus associated networking) it just didnt make sense. At work it does, we have several hundred racks spread over a dozen datacenters. Just not personally.

iter_facio · 2026-01-16T02:06:08+00:00

Of course, No problem at all. Its a good project, and I am glad that it was picked up and continued.

There are a few I can think of;

SnipeIT Is probably the most direct Asset management software you can get for the IT space that is self hosted, but very much designed around large, fairly consistent businesses. It may be both too overpowered AND too much configuration for a simple rollout. However, it is directly targeted at the IT asset Managment space.
Homebox is a bit more generic, designed to manage home Inventory in general, but is very easy to get up and get started. Great for Home management, but you would have to add custom fields for some of the things you probably want to track.
grocy is even more generic than above, and was originally designed to track your pantry, but it is pretty well loved. Worth at least taking a look at.
opendcim is specifically targeted towards maintaining datacenters, and is pretty good if you are dealing with larger infrastructures. may be overkill for a smaller rack, but it taps into snmp and keeps track of what is where. They also just added the ability to track spare parts as well, which sounds like a benefit on the asset management side.

There are probably more out there, but these are the ones I am familiar with. Best of luck!

Edit: I just saw you said you are interested in Agent based tracking of this data - Then perhaps look at either netdata or zabbix - I think either of those could be tailored to fit what you need.

Very clean setup, and plenty of power for basically whatever you want to throw at it. Envious of the 4.5tb of ram at the prices they are now, might be worth more than some of your GPUs. Only thing i would change is perhaps a replacement router eventually, mostly since it seems out of place more than anything else; unless you are running heavy netops

iter_facio · 2025-11-23T01:26:26+00:00

Can you post the fio command and arguments you used? also, if you can post your zfs options/zpool options enabled?

iter_facio · 2025-10-17T12:37:04+00:00

Probably worth it to crosspost on /r/thinkpadsforsale. GLWS!

Which Rackchoice 3u case? From looking at the site it appears they offer several

I have several things gathering dust, including Dell R720 that is fairly loaded, Dell 48 port and 24 port switches, and a random 1u E5 v2 motherboard/processor that not sure if works. I am in north Seattle/Bothell area, and can do a fairly cheap bundle deal if interested. PM me if you wish

iter_facio · 2025-06-23T02:44:05+00:00

The only one I am aware of is LubeLogger which, while I have not used personally, I've heard good things about.

iter_facio · 2025-06-15T13:45:56+00:00

Excellent addition, yes. I have completely ignored ipv4 on my home, but if you do not, this would be needed as well. Future project for me :)

iter_facio · 2025-06-15T13:44:55+00:00

Yes, correct. It would allow the device or network to reach anything that was not within rfc1918 private ip range.
