In a community colo, I have been running my Supermicro-X10 based Haswell server for a long time now, and it has turned 9 years old. I would like to refresh it, and I have been weighing the pros and cons of whether to go for Supermicro X12 or X13, especially since I also want to replace the chassis (with the now 9-year-old PSU and 9-year-old fans).

X12 wise, Supermicro sells a ready-made barebone: The SYS-510T-MR ; dual PSU, X12STH-SYS (muha! ;) ) mainboard. I just need to plunk in a Xeon E-2300 series chip, 128 GiB DDR4 ECC UDIMM, and a bunch of disks. This will get me an established platform, AVX512, but also older DDR4 and generally older-generation hardware.

X13 wise, Supermicro does not sell a ready-made barebone, but I could go for hte CSE-813MFTQC-R407CB chassis (also dual PSU) and plunk in a X13SAZ-F together with one of the ECC-capable Raptor Lake Core CPUs. I can then put in 128 GiB DDR5 ECC UDIMM and the same bunch of disks This loses me AVX512, and it's more DIY, but I do get newer-generation hardware and DDR5.

Price wise, the two are acually not all that far apart. Do you have any positive or negative opinions on both of these setups?

Rocket Lake is garbage and is an abortion of a microarchitecture. Go with the X13 instead.
