Case for homelab

[Akanox]

Hi,

Im in the process of looking for a new build, to act as a home server lab.
The lab is mostly running idle, but i sometimes have to spawn several big K8S clusters, with virtually redundant SQL clusters for testing = 100GB ram consumed.
So im planning on buying this:
1 x AMD Ryzen 7800X3D (In I5 / R5 would do as well)
2 x G.Skill Ripjaws S5 DDR5-5600 WH C28 DC - 64GB | Billig (proshop.dk) (128GB in total - would take 256GB if the CPU supported it)
1 x PRIME B650M-A II｜Bundkort｜ASUS Danmark
2 x 2TB Samsung 980 Pro
1 x NH-D15 (noctua.at)
4 x 860 1TB 2,5"

My biggest concern is the case, since it will be locked in a closet. (See the attached picture)
There currently is 1 x Lenovo P360 and 2 x HPE MicroServer Gen10 in there, where the new build, will take the Lenovo P360s place.
Its getting warm in the closet when the P360 and HPE servers are powered on at the same time - but the fans are still running low RPM and are silent. Its not ideal, but i dont see it as a deal breaker.


So the case can maximum be:
D 38cm
W 37cm
H 35cm


I have found these cases, that i believe are suitable - which one would you choose?

Very likely you'll run into a wall with 4 DIMMs.

DDR5 4 dimms on am5 -- what's working, what's not?

Are you running 4 dimms on the AM5 platform? What about LGA1700? Post a pic and details of your setup! Background I’ve been testing the new VSOC/agesa changes from AMD and 48gb dimm support. I am happy to report 96gb @ DDR5-6000 (2x48gb) is working great! I’ll have a video about that soon...

7950x: I want 4x32GB unless it sucks, does it suck?

Hi I am planning to build with a 7950x on an asus Pro art X670e. In various places I’ve been hearing that 4 dimms is a lot harder to run. I’m not expecting to overclock 4 dimms. If I buy 4 x 32GB of 5200 ddr5 will I have bad performance to the point where 2x32GB would be a better choice? I...

That was some interesting reading. As a developer, im not strong in hardware on that level - but i was under the impression, that with 4 DIMMs i would go from 5200 -> 3600 (https://www.amd.com/en/products/apu/amd-ryzen-7-7800x3d#:~:text=2-,Max Memory Speed,-2x1R)
My current Lenovo P360 runs with 4x32GB DIMMs and an I7-12700K - and havent had any issues there.

So are you suggestion that i switch to 2 x 64GB DIMMs instead, or that i should just be aware, that the speed will decrease to 3600 on my DIMMs if i go with 4x DIMMs?

It will probably run if you downclock the RAM, but then you lose the benefit of DDR5's increased memory bandwidth.


plus I think there isn't any 64GB DDR5 UDIMMs at the moment. 48GB DIMMs might be available so check around.
