For anyone looking for basic risers... I also needed a riser to add a graphics card to the quanta nodes. I went with "PCI-E Express 16X 90 Degree Adapter Riser Card For 2U Computer Server Chassis" off of ebay. They were $3.57 each. They are only one slot and are not an exact match in height but still work for what I needed. I also added a Quadro NVS290 graphics card. These are heatsink only cards and are officially supported in Windows10. You can find them on ebay for $40 for 10 cards plus $20 in shipping. So 20 graphics cards cost only $100. these have a dms59 connector so you will need a converter cable if you don't already have one.
For the fans, what I read is the fans are set in the bios to run at the slowest speed to prevent thermal throttling.
Memory- I have tested Samsung M393B1K70DH0-YH9 8GB PC3l-10600r ECC 1.35v, Hynix HMT31GR7BFR4C-H9 PC3-10600R ECC 8GB 1.5v, Gskill F3-12800CL9-4GBRL 1.5v, Gskill F3-1600C10-8GAO 1.5v. All work without problems.
If you just need a barebones server, these are great systems.
