Obsidian 1000D dual system - one loop?

[LoneTraveler]

Good afternoon,

First time poster and I am hoping for insight before my first ever dual system water-cooled build.

I have just bought a Corsair Obsidian 1000D and aim to house two systems;
1) Main Windows system with 14th gen Intel and 5000 series NVIDIA card (when released), so it will be several months before that is started.
2) Second system (mini-ITX) running my unRaid NAS.

Ultimately I want both systems water-cooled, however until my main system is available, the case will house just the unRaid system that I currently have in a separate case in the loft. The only change will be the transfer of the NAS system on to a GIGABYTE Z590I AORUS ULTRA mini-ITX motherboard to make it fit into the Obsidian. It will remain air-cooled until both systems are finished so that I can watercool everything in one go.

My question is, will I have any issues watercooling two systems on the one loop? The NAS system will be online much more than the main system.

I had planned to stick with all Corsair watercooling and hardware simply because it is a Corsair case with a Commander Pro unit, but if consensus says otherwise I'm happy to switch.

I am certainly open to any advice and/or suggestions however.

Many thanks.

Thank you both for taking the time to reply, it certainly gives me a lot to think about.

As for controlling the flow speed, I was not aware that that was a thing, I believed it was a one speed "set and forget" type thing for watercooling. I'll have to read up more. If it is the motherboard that controls the flow, I may need to opt for a dual cooling setup in that case.

Regarding the consensus to not use Corsair for all everything, would I have issues in connecting other makes of components to the Commander Pro, or does the community have a "go to" controller box to use instead?

Firstly, thank you to everyone who has replied, you have all been extremely helpful.

Lots for me to think about and look into.

To answer Bubo's question, yes I was going to have two PSU's, however looking at Mcnumpty2323's Phantek PSU suggestion, I'm now considering that. I'll be ensuring that everything that goes in to this build is geared towards water cooling.

I've always wanted a water cooled, top of the line machine, so thought I'd take my time doing this right. Just ordered a "GIGABYTE Z590I AORUS ULTRA" as I needed a mini-ITX board for my NAS system in the new case, once I've transferred over my current i9-10900K and RAM from my current NAS system, I'll utilise air cooling until I have the second (main) system also assembled in the case so I can water cool everything at the same time to ensure aesthetics are on point.

the phanteks is a quality psu with long warranty
made by seasonic i think
for people who already have 2 x psus i think
they also do a splitter board
pretty sure theres some dual systems in watercooled gallery section
may be useful to look at
though cant remember user names who posted them

I'll certainly give it a look, thank you. I didn't even know there was such a PSU. If it can power my whole setup then I think a dual PSU makes more sense.....more room then for water cooling goodies like a flow metre that was mentioned.

On a side note, I'm liking the colour scheme of this;
