Got enough to start posting about my build. (Don't mind the slight jank, I don't have the case yet.)
Got a literal steal of a deal on this second-hand Supermicro board, with CPU (Xeon E5-2620 v4) and RAM included. Yeah, it's a few generations older than what I'd like to have, but it simply could not be refused for the price I got it at it.
That said, I replaced said RAM with another deal on second-hand 8x 32GB SK Hynix sticks.
Noctua cooler because why not use the best?
I intended to use this spare GPU I had to check the BIOS and stuff, but it doesn't look like it wants to display out over it, so that'll be another time.
That's all for now. Still waiting for more hardware, so stay tuned.
