I’d like to build a threadripper system in this case at some point. They sell some of their cases, but not this one as far as I can tell. I suspect that it may be a slightly modified version of some oem case (unlike their other cases). Kind of looks like the Rosewill cases, but I suspect that it’s higher quality than those.
Oh yeah, meant to say the 4U one. The 3U one can’t accommodate supplemental power connectors on GPUs so it’s kind of a stupid choice for a gaming PC or workstation. Limited to media playback or server.
There are metal cases that look like that one sans the brushed front and the 3 button/lights. You could always get something like one of those and modify it to look like that one.
Aliexpress and alibaba so far show nothing that looks exactly like that.
