Build Advice I need a quick check of components compatibility ?

I'm willing to spend around 7000-8000€ for the PC alone. I live in Austria, Europe and I don't think I'm near a Microcenter. I have already decided on multiple parts, but it is my first time so I am unsure if it works well together. I am looking for a Gaming build that can handle 4k/240hz in demanding games and is as quiet as possible. I am not going to do overclocking for now. I am planning to undervolt the GPU for quieter performance. Unsure if I have to undervolt the CPU too then...

Already picked parts:

  • CPU: Ryzen 9800X3D
  • GPU: MSI GeForce RTX 5090 32G SUPRIM SOC
  • Motherboard: ASUS ROG Crosshair X870E Hero
  • SSD: Samsung SSD 9100 PRO 4TB, PCIe 5.0 (as main ssd with the Operation System of Windows 11 Home)
  • SSD2: Samsung SSD 990 PCIe 4.0 4TB (for games)
  • PSU: Seasonic PRIME TX-1600 1600W Noctua Edition
  • RAM: G.SKill Trident Z5 Neo 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory

Other setup parts already picked:

  • Mouse (I'll use my current one)
  • AULA F75 Keyboard (using it wired)
  • SteelSeries Arctis Nova Pro Heaphones (wired version)
Parts still needed:

  • Monitor (4k/240hz and an OLED screen. It doesn't really matter if it's curved or not)
Parts I'm considering/unsure about:
  • CPU cooler: Any quiet liquid cooler (I want a liquid cooler that I can run at silent mode even during heavy gaming. And one where I can maybe change the fans to Noctua fans. Looking at the Arctic Liquid Freezer ||| Pro but it is way too thick for the ASUS case and 3mm too thick for the Antec case too...would it still work with the Antec one though?)
  • Case: ASUS ProArt PA602 Wood Edition Tempered Glass (It doesn't work with the PSU's dimensions (190mm vs 210mm) so could I just remove the hard drives and it would fit?)
  • Case2: Antec Flux SE (No idea if this works with the PSU's dimensions...According to the website I think it does "Max PSU Length: (Include Cable) ≤ 235mm with HDD)"...also it doesn't support 200mm fans so thats a bit of a minus but the sound-damping side pannels are good)
  • ASUS CASE - Fans(changing the built-in ones): NF-A20 PWM 200x200x30mm (x2 as intake), NF-A14x25 G2 140x140x25 (x2 as exhaust)....do they fit into the case? The built-in 200mm fans are 200x200x38....
  • ANTEC CASE- Fans(changing the built in ones): NF-A14x15 G2 140x140x25 (x3 intake on front, x2 intake on bottom, x1 exhaust on bottom)...this will balance with a 360mm AIO mounted on the top I think...
  • Extra: Thermal Grizzly Contact Sealing Frame AM5 (Is it easy to install and does it improve/decrease performance in any way?)


One more question: Are CaseKing and Amazon safe to order from trustable? Or do I have to buy every component from the offical websites?


Please correct me if any of the components don't work together or if there are better options for this system and I'm open for any tips with installation, picking parts, etc... and please tell me cable management comes with an instruction for every component because I have no idea where to plug in what... :c

If you go here;
you can choose Austria as the location in the drop down menu(for countries) and you should also see a compatibility listing for your parts.

For your ram, look at 2x32GB kits with AMD's E.X.P.O advertised on the packaging or their product site. If you want to pic up something from G.Skill, just look for their Neo range of memories.

CPU: 9800x3d (delidded for better thermals...unsure how to mount it, please explainations and suggestions)
For a newcomer, I would advise against delidding.

Parts I'm considering/unsure about:

  • CPU cooler: NH-D15 G2 (mounted offset so it works with the delidded CPU...I think? please explainations and suggestions here too)

Thank you very much!

Thank you, I'll check it out. Sadly it can't calculate how fans are compatible with the case which is my biggest concern on this system.

I'll go along with the G.SKill Trident Z5 Neo 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory. Thanks for the reccomendation!

Thanks, I'll simply look for a high-end AIO which can perform well enough on silent mode.

To find compatibility for fans, check out the specifications page for the case you want to buy. For instance, the Antec Flux SE or PRO. In the specs section it says, "FAN SUPPORT," and then list how many of what sized fan can go where in the case. This is the same for the support regarding radiators just below. Any time you can put a 140mm fan on a case over a 120mm, go with the 140mm. Bigger fans don't need to spin as fast to move the same amount of air so they are typically quieter. There are some better fans than those noctuas out there as well, but they may be hard to get in Austria compared to the noctuas. The Phanteks T30 120mm and 140mm fans are great, and so are the Lian Li P28's.
