Just wanted to show off my server. Runs Proxmox as a hypervisor with TrueNAS virtualized with complete control of all the HDDs since the HBA is passed through.
Built this a while ago as my first server from parts off ebay. You might wonder why all the tiny fans? Awnser is that 1TB of registered ecc ddr3 uses 400 watts so idle power consumption of the whole system is about 800W, live and learn ehh!
Did you say DDR3 
?
Ouch, my soul felt that pain.
However, always looks good with 24 HDD’s staring at you 
. Where’s your LSI HBA in the last image?
Yup ddr3, in retrospect a broadwell system with say 256GB of DDR4 would have been better. At least I will not run out of ram anytime soon. HBA is in the second pci slot from the right of the image between the two 4x m.2 riser cards.
I have a hard time wrapping my head around that kind of alleged power consumption. While my system uses DDR4, my NAS has 128GB of RDIMM and it idles at around 100W. No doubt that the power needs for DDR3 are higher but I suspect the RAM has less to do with idle than the CPUs or the drives?
Put another way, I wonder if your CPUs have more to do with the idle power needs of your system and the RDIMMs are somewhat innocent bystanders getting fried in the process? What kind of processors are you using and are there perhaps some less-power hungry versions available, if power consumption is a concern?
There seems to be little room inside that case and SuperMicro cases usually include massive banks of screaming fans, plus molded motherboard covers to maximize airflow over all motherboard components. Did you retrofit Noctua fans in place of high-flow OEM screamers?
Well that is one hell of a server! The first thing I saw were all the fans as well and I didn’t spot the HBA either until you pointed it out.
That is one power sucking beast.
I like how well you laid out the cabling, very nice.
The question on my mind is, what is it used for?
Obviously, it is a Model for photographs. Just look at those beautiful pictures posted. I dont’ see a speck of dust. 
I had overheating issues because of the ram power draw when late spring hit, thus all the 20mm fans attached to the banks so it’s definitely drawing. It might be 350 or 400 for the ram itself, I have not measured the difference by pulling ram sticks, however the internet says the rule of thumb for ddr3 is 3W per 8GB and linear scaling. That calculates out to 1024/8*3=384W. Also remember that you have both 1/8th the ram capacity and ddr4 using 30-50% less power.
The main fan’s are 12012038 5500rpm fans, but rpm limited to avoid having a jet engine in the attic xD. They would be perfectly able to cool everything if both I and my neighbors were deaf. That’s also why there is so many fans. Turning the main fans down caused air to stagnate around the pcie devices and ram banks. CPUs are no problem. Have never seen them hit 80C even in really high summer ambient temperatures.
Nas duties, backups, jellyfin, arr suite, frigate, gitea, nextcloud, photo editing in a vm ect. I do also self host a couple of websites and it does serve as a DAS for a gaming machine.
I’m not going to pretend that I needed all that ram or that I use all the cpu. I wanted to play around with proxmox and server hardware without going bankrupt. I do like the chinese case though, it was very nice to build in.
It is a very nice looking machine. You will still go broke paying the electric bill 
What I’m currently running. VM 115 is currently using the P4 and 121 has the 4060 for transcoding.
The plan forward is to replace my retro iphone with a lineageOS or grapheneOS or something similar. Then I’ll just need a proper google maps replacement that’s self hosted and I’ll have achieved a modicum of digital freedom.
I also switched from iPhone to GrapheneOS.
Are you happy with your Custom ROM?
Impressive build! Congratulations!
