    Does this exist? Can anyone share a model number?

    basically something like this: SuperChassis 825MBTQC-R802WB
    but more affordable and takes a normal ATX or EATX motherboard and not some proprietary board.

    Basically I have a Plex transcode server setup for remote users, which transcodes on the GPU (EVGA GTX 1660, power savings). It is currently in a 4U SC743 chassis with a X9DAi motherboard with E5-2630Lv2 CPUs. But it feels silly to be taking up this much space for a relatively low power system. it runs fine, I just want something smaller. I just want a bare chassis with PSU, I'll add my own MB/CPU/RAM/GPU/etc.

    I do really like SM stuff, but if SM doesn't have something that fits, I'm open to other suggestions, but I do strongly prefer a SM solution.

    hmm...i doubt there is any. Only proprietary form factor takes full-height in 2U.

    I found a single model that seems to allow it: 216BE2C-R920WB

    but I don't see any availabe on ebay and something tells me it would be expensive.

    what about non-SM options?

    i dont think 216BE2C-R920WB works for regular ATX or EATX, you can find the compatible MB for the chassis on SM site.

    But the same page also lists the MB layout as ATX and EATX. Which should correlate to the MB mounting points. And is a standard. Unless the info on their page is just wrong.

    I don’t always trust the recommended motherboards. If it has ATX standoff layout. I can put any ATX board in it.

    But it’s moot because I can’t find that chassis anyway.

    Any non-SM options? I’m browsing Newegg now. There are some, but they look pretty jank so far.

    An ATX board is 99% unlikely to work with a riser needed to fit a FH card in 2U.

    If space isn't a concern I would keep the 4U it makes things a lot more simple.

    As long as I can physically secure the GPU to the case in the horizontal position, I can use a flexible riser to get it hooked up to the PCIe slot. that's really simple.

    I just need a 2U case to fit it all.

    currently only have a 12U rack (full depth)
    1U- PDU
    1U- switch
    1U- router
    3U- FreeNAS box + Prime Plex server (serves LAN only) + various other jails and VMs
    4U- remote plex transcoder
    2U- UPS

    so yeah, I'd like to free up some space

    Could you not combine the PDU/UPS functionality?
    I'm going without details of course ... but seems like you could free up 1U there.

    If you are dealing with 4-post rack ("Full depth" - whatever that means in actual depth measurement) ...
    could you not mount the switch and router back to back to free up 1U?
    (again ... just visualizing without details of your equipment and setup)

    cool, I'll look into that. I just said ATX to get an idea of general options. I have an X9DAi now, but not necessarily opposed to downsizing to an ATX case if I had to. I just didn't want to be stuck in proprietary-ville.

    my card is only 10" long. so that's fine.

    combine UPS/PDU, maybe, but I like the way it's setup now with things plugged into the PDU that are close to it (router/switch/rpi) with short cables, and it gives me easy access to plug something in at the rack if I need an outlet real quick without fumbling around behind the UPS.

    yes 4 post rack. full depth was just expressing that this is not some tiny network rack. it's adjustable, max depth something like 40" but I think I have it set to like 30-32" or so.

    I was looking at that case. Seems a bit pricey though and would mean I have to change some things. What PSU did you use?

    We ended up using a 250W "1u flex psu" from amazon that was ~40 dollars although if you want anything that pulls real power I'd suggest something bigger than that
    This is the same form factor and would give you a bit more power

    So to clear up some confusion here, the chassis from supermicro that end in WB are WIO chassis. They are ATX form-factor at base, with a different rear window than the equivalent non-WIO chassis to support horizontal mounting of the PCIe cards - if I remember correctly, 3x full height on one side and 2x half height on the other. Other than the rear window and MAYBE one or two standoff holes, they're identical to non-WIO chassis.

    So yes, you could in fact get one, put a standard ATX or EATX board in it, use a riser cable, and it should work. Note too, the Supermicro WIO motherboards tend to be an awful lot cheaper than standard EATX or ATX boards are.that's part of why the chassis are a bit more; the other part is there's fewer of them.

    Source: converted my ancient X7-generation SC815TQ-R700B to run an X9DRW-iF successfully by replacing the rear window with a WIO window - you can purchase them from Supermicro's RMA department - and using a couple of plastic standoffs where the older chassis was missing standard ATX standoff holes.
