Anyone want to do group buy to NYC?
I don’t have a car, but could meet near penn station or Grand Central!

The 512 is a great short-depth 1U chassis; it’s about 16" rack depth. This is very similar to the famed R210ii that’s so popular for pfsense. This chassis should be a bit more flexible with boards.

There is space for a single 3.5" drive or a couple 2.5"; the PSU has SATA power. The SCL only has SATA2, no SATA3. Half-height PCIe works if you pick up a 90-deg riser; beware that riser dimensions are not standardized. No IPMI on this board.

You can replace the blower with some quieter 40mm fans (Sunon V3/V4 maglev or Noctua if you don’t mind the price). With a low-power CPU, cooling needs should be lower. The PSU has a 40mm that probably isn’t replaceable, though.

This price is about what it’s been at for the past few months; it’s still a good deal. If you want a 1U gigabit router and noise is not a big deal (or you’re willing to mess with fans), this is very close to turn-key – no add-on NIC needed, just pick up a cheap CPU, a bit of RAM (2-4GB), and either that cheap SATADOM or a spare SATA SSD you have lying around.

(In case anyone is about to ask: no, don’t run Plex on this! It’s also not worth it if you were planning on using the board for a NAS in a case with more drive bays; there are plenty of bare X9SCL/M-F available. Contrary to the listing, this system with a single 3.5" drive would not make a good storage server.)

The Sunon 40mm V3/V4 fans I’m finding are about the same price as Noctuas. Any source for cheaper ones and how do they compare to Noctua as far as noise and performance?

Noctuas are good stuff, the only issue is they know it, and charge you accordingly. Sunons should be around $5-7 each on eBay. Here’s one listing; both the HA and the KDE V3 are fine. Those are 10mm thick; there are also 20mm thick ones. From China, so there’s an off chance it’ll be a counterfeit, but for such a low-revenue item I don’t know if it’s worth it to them to counterfeit.

FWIW, I made an offer of $73.99 and the seller accepted. So for $105 shipped I have the beginnings of a new pfSense build.

I have been running an old Linksys/DDWRT router for the last couple weeks since my circa 2018 USG died. I reached out to Ubiquiti for support, but they were firm on their 1 year warranty.

This looks great, I’m looking for a rack mounted 1u server for pfSense under $250 and this certainly looks like one of the best options for the price.

My top 2 priorities is that it is as quiet as possible and not too power hungry. I would rather spend a bit more up front to get both of those options.

Can anyone comment on if this would be my best option or if there are better ways to go? Thanks.

This won’t be silent, but it should be relatively quiet. You can replace the blower fan with Noctua 40mm, but they aren’t cheap.

The PSU is kind of a toss up though, it could be loud, tolerable, quiet, or silent. Just depends on the model.
