rsync.net is built entirely on supermicro head units and, until a few years ago, their JBODs.
Then they got greedy and tried to do the old "certified drives" bullshit with their JBODs and that was the end of that ... now we use the celestica JBODs we source from IX systems.
Head units are still supermicro, though. Fingers crossed ...
My favorite chassis so far has been this generic one, the fans suck(just buy a new set of good fans right away) and supplied drive bays suck. but look at all them 5 1/4 bays, bays for days. You can put every stupid hotswap bay, fan controller and drink holder gimmick you want in there. and still have room for more.

Stock market shenanigans are also hardly a new experience for this symbol, either: Already forgot about the discredited 2018 Bloomberg hit piece? https://www.bloomberg.com/news/features/2018-10-04/the-big-h...
After the power supply failures we started switching to their "twin^2" units (or something named like that) which were 2U RM boxes with redundant power supplies and 4x semi-blade servers, which again we could provision for the sub-$1,000 price.
I've since looked at pricing some systems from them as an alternative for the Dell servers we've been buying more recently, and oddly enough the prices all seem to be in the $10K+ range. A pretty big shock to see what used to be "dirt cheap servers" up in that range, but the RAM and SSDs really add up. Even though Dell seems to have insane pricing in their configurator for RAM and drives...
As an employee of a customer of Softlayer, the servers were very reliable. I have my personal hosting on a rented SuperMicro server now, and pretty happy with it, even if the hardware is 10+ years old (Xeon Lynnfield) and the IPMI requires ancient JNLP that barely works ... I only barely need IPMI (gotta console in to decrypt the disks on reboots, and it was handy for setup)
