I hope to receive soon my HDplex!!

@dondan one small question: the plastic division is supposed to be removed with the 120mm AIO setup?





Sorry I'm new here, but is that a 120mm AIO? I thought you were limited to short ITX GPUs IF you use 120mm AIO..

i.e.
1) Internel 120er AIO. You have to use a thin 120er AIO like the Corsair H60 and a ITX GPU. Flip the SFX-L PSU will allow you to mount the AIO on the SFX 120er mount points.

i.e.

You can mount a 120mm AIO by either using an itx GPU or by using a HDPlex instead of a SFX PSU, the first pics he will be using a HDPlex.

If you look at this post you will see the HDPlex mounted.

I'm thinking of building ITX system on Dan A4 with 120mm AIO, because I want silent system and I don't need much GPU power.

Can you please tell me if my spec looks ok?
CPU: Intel i9 9900K
HSF: Corsair Hydro H60 v2 + Noctua NF-A12-15(with low fan speed controller)
M/B: Asus ROG Strix Z390-I
RAM: 32GB G.Skill Ripjaws V 3200
GPU: not sure yet, any recommendation besides Gigabyte GTX1070/1080 Mini? I don't need much GPU power..
SSD: 1TB Samsung 970 EVO
Case: Dan A4-SFX v3
PSU: 600W Corsair SF600 Platinum

Thanks.

Oh, ok thanks for the info. I don't wanna use HDPlex, because that also require large brick power adapter, right?

Looks good. BTW 450W Corsair Gold is enough.

There is also a RTX 2070 Mini available:

It will be available together with v4 release.

Here are my current changes for v4.

  • New riser with 185mm short cable (like this https://www.sfflab.com/collections/parts/products/pcie-extender-adt) will drop retail price $10-$25
  • Adding 92mm fan mountpoint + ventholes under the motherboard
  • Lifting the PSU 5mm up to have more space for 92mm AIO
  • removing 120mm AIO bracket from included to optional (orderable over SFFLabs parts section)
  • USB 3.1 gen2 Typ-C at the front
  • adding mointpoints over the motherboard for 120mm AIO bracket to be able to mount a 120mm fan above motherboard
  • making the PWSW cable longer for better access on cheap MSI AM4 boards
  • changing HDD bracket to support for 15mm thick drives
If you have more ideas please let me know.

I just got my Dan A4 v3, and I've had great fun tinkering with it. It will be a useful portable workstation once I've got the cooling airflow worked out. My build uses suggestions from the forum&Youtube, with Asetek 92mm 545LC with Noctua NF-A9x14 PWM for CPU cooling, but the other motherboard components are getting so hot the CPU can't get close to good performance. I'll try adding another NF-A9x14 or Akasa AK-FN076 on the bottom, as well as on top of the motherboard and on top of the case, with the top&bottom activated only under high temps, so the case will still be low-noise under normal use.

The airflow seems to be the main issue with this case, and your changes 2,3 and 6 will help with that. I'd have two other ideas:

1) add flexibility to mounting the motherboard, by adding alternative screw positions:
- If I could mount the motherboard 5/10mm higher, I could put a 20/25mm thick fan on the bottom, or have more air clearance for a thinner one. And if I could mount it 5/10mm lower, I could put a thicker fan on the top.
- If I could mount the motherboard 5/10mm deeper, I'd have more space for CPU & motherboard fans. Or with even a deeper placement someone could remove the double-chamber, positioning a GPU on the same side as the CPU with more airflow for the motherboard.
These variations would also allow extending an AIO tube more if needed, and reposition cables for better fit.

2) replace the mesh panels with full-coverage mesh that doubles as mounting points and ventholes: Currently even the recommended Corsair 600 gets a quarter of its intake covered by the meshless part of the side panel. Adding intake/exhaust fans is handicapped since the mesh holes don't have the same airflow impedance as regular case fan ventholes. And its difficult to mount any fans, since aside from mesh holes and CPU/heatsink brackets there's nothing to attach fans. To me the best option now seems partially mounting fans using M2.5 bolts&nuts to the available mesh holes, and this sounds bad.

Idea 1) would require more holes in the case. Idea 2) could be mostly implemented with alternative side/top panels, if those could be available for purchase. I'd buy a set straight away :)
