They support NVMe and have a PCIE riser; if you get the little adapter from Lenovo’s proprietary slot to standard PCIE, you can run it as a nic, or get an HBA with external SFF-8008 ports and then find a cheap enclosure to use as a custom DAS solution.

I would recommend:

• go on eBay and find some sort of cheap Lenovo/dell/hp thin client for your secondary node. You can find workable 1L-class boxes for around $100. You can get away with some of the older m700/710/900/910 tiny models, but the extensibility of the m720/920 tiny models is going to be much better.
• for your primary, I think you’d probably be best off finding an old server tower with 8 3.5” bays - if you’re lucky and on-the-ball, you may be able to snipe something like this, but shipping is of course going to be a bitch. An alternative is to pick up another one of those thin clients (making sure it’s a model with USB3, but preferably 3.1 or 3.2 whatever the gen is (side note: fuck anyone involved with the USB versioning scheme, because it’s absolutely indecipherable) that can actually support meaningful data transfer, and then just find a cheap DAS and connect it to that node.

Some foundational questions:

• budget?
• rough desired capacity?
• desired level of resiliency?

Just get an old 1L class dell/hp/lenovo, a riser to adapt the proprietary expansion slot to standard PCIe, and an old x520DA2 nic. You can find all of this on eBay. Then, just slap pfSense or OPNSense or whatever you want on it.

Edit: and the switch is the 9-port version of the one you posted.

Holy shit dude. You can take like a quarter of that and make an absolutely silly system, and make a decent chunk of change selling the rest.

Lmao dude thats simply not happening at that price.

You could get part of the way there with an old Dell server, but you’re probably gonna be paying closer to 2-300 for a decently spec’d one like you’re describing. You’re probably gonna be looking at a 10 year old twin quad core setup with a tdp of like 500W combined for JUST the cores. Your power bill is going to murder your budget, even if you somehow find a magical deal on the box.

I will be driving my 03 1.8t 5mt Jetta into the ground, thank you very much.

It is 100% a great idea to see how you feel about the concept of self-hosting with an old machine. If it’s really old (and I’m talking like anything from before about 2008-2010), perhaps consider snagging an old “tiny”/1L-class box from eBay for cheap. Dell, HP, and Lenovo units can be found for WAY under $100 all the time, and slightly more modern units can still be had at a reasonable price, depending on the model. They’re great platforms to play around with. Just shove a cheap SSD in there and play with it.

Time for a repo fork?

I think your best bet will be an SFF/USFF/1L box used on eBay. The tiny/1L ones mostly have energy-efficient CPUs (like intel T-suffix SKUs), but they also don’t support the SATA connections you specified (unless you go for an external USBC/TB3 enclosure, which many people do)

Yeah, though the advantage of the T sku CPUs is that they have ultra low tdp. Great for 24/7 boxes.

So the big gain you’ll likely see is bang/capability for the money. If you’re careful and wait for a deal, can usually find 1L boxes for like $50-75. Get a cheap m2 ssd (and back up your confs regularly if you’re not running raid z2). The nic is going to be anywhere from about 30-70, but you’ll need to do your research on exactly what capabilities the thing you’re buying has (for example: I had a false start initially, because the RJ45 10G nic I found couldn’t negotiate at 2.5G (what I’m running now), and it’s actually pretty hard to find a 2.5G enterprise nic. Make sure the nic is intel, too - none of that Realtek crap, which is less performant and often has stupid driver crap you have to deal with under Linux and BSD (pfSense). You may want to spend a few extra bucks and get the Lenovo external pcie mount plate/bracket for aesthetics/“don’t stick your fingies in here”, and you will need an adapter for Lenovo’s proprietary PCIe-but-not-a-standard-PCIe-port thing.

i5 8500T. I don’t recall exactly what the power draw is, but iirc it’s in the 20-30w range - admittedly a bit high, but that’s likely due to the old LSI nic in there which is technically an enterprise-grade card, and not terribly power efficient. Nonetheless, works great, full 10G speed, no thermal issues in the last few months I’ve been running it (in the summer, so I should be totally fine in the winter).

Go on eBay and look for “tiny” or USFF boxes. Dell, HP, and Lenovo make various models of 1L units that are commonly available. Just make sure to do some research on what the specific hardware capabilities are to make sure they satisfy your needs.

As long as it’s not error or critical to touch, you should be good.

What temps were you seeing before adding the fan?

oh, you.

It’s also piped to sudo so that’s super cool too

Fair enough. There are no rules for homelab; do what you want!

Out of curiosity, are you running a repurposed 1L OEM box? I’ve picked up a handful of those for dirt cheap, and they’re kinda fun to play around with!

Huh, proxmox on a i3-4130? That doesn’t choke on cpu? TBF, I’m assuming you’re running several other VMs. Also, why not docker?
