I have no doubt a Supermicro HBA will work in a Supermicro motherboard and chassis given the correct Supermicro risers or other accessories. What I was questioning was where the OP said: "it fits into a standard PCIe slot and works nicely there as far as I can tell" - which to me sounds like you could use this HBA in a *NON-Supermicro* motherboard. I was just wondering if that was truly the case, given how in the photos it looks to be arranged physically backwards from a regular PCIe card, and given how you mention "The UIO slot itself is proprietary". But some more digging on Google has turned up a few mentions along the lines of: """ This card plugs into a normal PCIe 8x slot but the metal mounting bracket bolted to the card is made for a UIO slot (which is why it's so cheap). All you have to do is remove the metal bracket and zip-tie the card to your case for mechanical support. Electrically it'll work fine in a PCIe x8 or x16 slot. """ If someone wanted to make PCIe compatible brackets for this affordable card, they'd probably sell a fair number to small shops or home users. Barry
