Custom high-end small form factor PC

[FOG_Yamato]

Budget (including currency): 5000 EUR (can go a bit higher if there is a substantial improvement)

Country: France (can also buy components from the US)

Games, programs or workloads that it will be used for: Unity Dev Environment, Fusion 360, Solidworks, MSFS 2024 and other AAA games.

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): 
I want to upgrade my almost 7 year old computer to something modern, been eyeing the 9900X3D with the 5090 as the baseline parts that the build will be designed around, the case I'm thinking of making on my 3D printer or CNC mill so it's not needed to be purchased, another thing is that I'm tired of any RGB rainbow barf and water cooling (current PC has hardline water cooling), also due to the size of the old PC I was thinking of building a a small form factor PC that would be compact and fairly well ventilated with mesh panels on all sides. The current setup also is using 3 1080p monitors with the main one being a 188Hz one, upgrading to triple 1440p monitors is also a potential idea that I'm considering outside of the PC budget. The other peripherals are not needed. I plan to buy the components besides CPU and GPU earlier if they go on significant sales (Black Friday, Christmas sales), if not then when the 9900X3D and 5090 come out.

This is the preliminary build that I thought of, any improvements/suggestions are welcome: https://fr.pcpartpicker.com/list/pxBgTY

EDIT: I also am going all SSD based storage with a requirement of about 6 TB minimum.

Do you NEED it to be small or just a regular desktop size?

 

Flat out with your parts choices its just going to end up being the size of a regular mid tower. Not really a way around it at all.

 

As for cpu wait for benchmarks same as gpu. The 7900x3d is BAD flat out. It games worse than any other x3d to the point where overall the regular 7900x is better and is worse than the regular 7900x at productivity. The 9900x3d may be better but if its again half of the cores only being x3d do not expect that.

 

5090 who knows how that'll perform. Doesnt sound like you need it tho? Unless you really need 24gb+ vram?

 

Anyway easy to save a bunch in that pc for no difference

500 saved for no performance loss what so ever. Ram is even faster as ryzen can LOSE performance running past 6000mhz.

It's a confusing (or confused) part list

7900X3D is epitome of indeciveness ; you got the budget for 7950X3D (or 9950X3D later), so why ??

You want SFF, but havent chosen any case, and then want a 4090 and a ginormous NH-D15 that won't fit in any SFF I ever have heard about !

SFF are meant to have either LP coolers for low power CPU, else an AIO is required

If you want the fastest SSD possible get Gen5 as boot drive, then a cheaper 2nd drive will make no difference

No need to spend +400EUR for a "top tier" 4090 that runs within 3% of a lower tier one...

And 6800MT RAM won't run Gear1 on Zen3, recommended max is 6000CL30

 

Could suggest this :

Thank you so much for the advice!

I've put in the 7900X3D and 4090 as placeholders for 9900X3D and 5090 as they're not out yet, the SFF case is not a problem as I'll be modelling and manufacturing my own case for the PC, the cooler I already have from a friend's build that decided to go with a AIO instead but I can always go for something else if it's less maintenance than a custom loop and can adequately cool the CPU. I had no idea that having faster RAM is detrimental for Ryzen! I'm coming from Skylake CPU so all this new DDR5 stuff is uncharted territory for me.

Ok, but the 9900X3D makes no more sense than 7900X3D, get a 16 cores 9950X3D, comma

And really a NH-D15 will kill the whole "SFF" goal, as it's like 17cm high, I'd really can't recommend it !!

You can still go small but keep in mind that the 5090 is ptobably going to be a HUGE 4 slot card and the nhd15 is BIG. Its a great cooler no reason not to use it!!!!!!

 

Hencr why I opted for a not beyond stupidly overpriced board as simply put that 5090 is going to even cover a full matx board. Just by parts choice a small form factor pc with these will just end up looking like a small mid tower. Hence why no need to spend on a mediocre itx board when you can have a nice matx board for a FRACTION of the price.

 

Also the 9900x3d if it does the same as the 7900x3d with the cores it stil wont make sense to get as it wouldnt be good at its designed for tasks with the x3d cache and also wont be as fast as a normal 9900x. Hence why I dont recommend it. Of course wait for review but unless its all x3d cores I wouldnt get my hopes up.

 

Also since this pc will be bigger by pure fact of the nhd15 and 5090 just get a atx psu then. Save some money there and get a nicer unit!

So after some thinking decided to switch it up and go for mATX as that would still make it a decently small PC, would just need to borrow the large format 3D printer from a friend for the actual case. Put the 7950X3D as the placeholder for the 9950X3D, which will hopefully have all core 3D V-Cache like the rumors say, if not then I'll go for the 9800X3D. The 4090 is still staying as a placeholder for the 5090. My main concern is the power supply being enough for the whole build as it seems like all of this will be fairly power hungry so I don't want to run into an issue with power delivery.

So this is what I came up with based on your recommendations:
