What is the best AMD processor and board for a Lian-Li D8000 server cube build as an alternative to competing Intel solutions? I tried the Supermicro brand AMD H8QGI-F a quad AMD Opteron Socket motherboard, but the back plane wouldn't line up with the place for the I/O shield in the Lian-Li D8000 and ended up being a huge disappointment that I still haven't been able to successfully complete this build besides the other reason it's taking so long being the cost of all the parts desired. I found out that the Supermicro brand AMD H8QGI-F quad AMD Opteron Socket motherboard was actually intended for the Supermicro CSE-828TQ+-R1K43LPB chassis a 4U or 5U chassis, which is another reason for the disappointment and delay in completing the build because that's not what I had in mind for the build. I actually intend to complete this build as a newer technology computer for a mini mainframe or mini highend graphics workstation with a lot of internal storage being that the Lian-Li D8000 can support up to twenty two 3.5 inch hard drives and that currently hard drive capacity is available at up to 12 TB for each hard drive, even if they are mechanical or if I have to settle for a minimal of 1 TB if I go with SSHD's for the most affordable hybrid Solid State and combination mechanical storage option out there. I had the same problem with the Supermicro X10DAi-B motherboard, which is a dual Intel Xeon 2011v3 LGA socket board too because the backplane wouldn't line up right with the place for the I/O shield and there was a problem with the default spacer alightment too, which there didn't seem to be anything I could do about it without possibly ruining the removeable motherboard tray to modify the tray so that I could actually use this board instead of the Supermicro H8QGI-F AMD Opteron Socket motherboard either. One other thing noting is that all Xeon 2011v3 boards are also meant to support all Intel 2011v4 processors too, so going with at least a newer Supermicro branded solution if not some other motherboard brand like Gigabyte, ASUS, ASROCK, or Tyan is not even an option and is a little weird. Finally, any Intel Xeon Scalable socket 3647 motherboard solution and not the equivalent single processor solution being the Xeon W socket 3647 are also only manufactured by Supermicro and I didn't like that some of the security features were taken away with at least the lowest end Intel Xeon Scalable Bronze and Silver, even if Intel had to do it to get the prices down on these processors at around $200 to $300 for the Xeon Scalable Bronze and at $600 or slightly higher for the Xeon Scalable Silver, which is the best they can do and the best I can probable afford without taking longer to wait until I can afford the preferred Xeon Scalable Gold or Platinum processors that might still have all the security features I would still want and all the other features that make owning a Xeon Platform computer so great especially more system memory and higher graphics processing cababilities as well as other higherend processing capabilities. Other than that if I actually wanted to do this with AMD Epyc I don't know or haven't found the parts I might be able to do it with and Intel Itanium is out of the question because it's now only suited for highend server and not graphics workstation as well as has been said to be discontinued and have fewer cores than the highest end Xeon's now. I know this is a really ambitious consideration for a system built too, but when I sawy the case I couldn't think of a better idea for build than this either as a dual processor or quad processor build to replace my Supermicro SC850P4 server cube that was severly out dated from around the time of it's original release in around 2005 or so that used the P4QH8 or P4QH6 motherboard that I actualy could only find the P4QH6 motherboard, but couldn't find any retailer that would sell me the memory riser board so that I could actually install RAM into the computer and after trying to sell on ebay just ended up donating to the College I got my three associate degrees in Computer Network Administration out of after being ridiculed for even trying to sell it for a decent amount to make a reasonable amount back for how much I spent on it while even trying to restore the build or complete it either way considering I actually did just end up buying the SC850P4 chassis without realizing I could only use it for the P4QH8 or P4QH6 motherboard from Supermicro and not the P3DRIII from supermicro, which I actually need the SC830 for.
