Info needed about Supermicro SuperServer 5028TK-HTR https://www.supermicro.com/products/system/2U/5028/SYS-5028TK-HTR.cfm

Problem. No info about them, though they announced almost a year ago. Googling brings nothing, News bring only PR stuff, Twitter search brings nothing.

Questions. Are those servers real? Anybody used them? Which OS installed? Installation smooth? How they handle cooling under load? Any issues?
