I'll just do an Order using CraftCloud for ~30 Pieces of that IO Shield (I'll see if I can get it printed in Metal Sheet, might be way too expensive though), as well as some other Stuff I could 3D Print as well.@luckylinux Regarding IO shield, you will be printing it on 3D printer for those cases you bought?
For rack panels/blanks i usualy order from thomann, they got 3u 3x120mm at 119dkk.I was looking for a 4u 3x140mm Panel but I cannot find anything unfortunately, neither on printables nor thingiverse.
For a 42U Rack that would need 10 x 4u (plus 2 Blanks) otherwise 14 x 3u. Saying 3 fans on each Panel, that would be 30 x 140mm Fans or 42 x 120 mm Fans respectively. But on the good Note, they should be able to be tuned down a lot either by PWM or by using an Adjustable Power Supply.
I already bough from both and yes Arctic is very cheap and quite good and my goto choice for fans. Arctic p12 Pwm is the last I started using a while ago.For rack panels/blanks i usualy order from thomann, they got 3u 3x120mm at 119dkk.
Standard stuff that is used for stage/audio also tends to be cheaper there than in the IT space for consumers.
(They also got a solid selection of PDUs if you need some)
Arctic cooling has 5packs of their f12 and p12 fans at a decent price.
Its not something you need either way, so id guess you have a bit of a budget for the setup when buying it to begin with.Anyways, 119 dkk * 14 blocks + say 5 eur / fan * 42 fans is still quite the money...
Well yes and no.Its not something you need either way, so id guess you have a bit of a budget for the setup when buying it to begin with.
If anything, then something like this from Delock (a bit Cheaper at 59 DKK): DeLOCK Rack cover Sort | Stort udvalg, billige priser og hurtig leveringIts not something you need either way, so id guess you have a bit of a budget for the setup when buying it to begin with.
You will need some airflow in the case regardless of your rear pull config tho.Well yes and no.
Unless you want the loud 1u blower fan screaming and rattling at you
I was just thinking plastic is cheaper than metal.
But I might also do with wood maybe.
Well, 3 x 40mm each Server (1U) isn't much different than 3 x 120mm each 3U in Terms of Cost. But it will likely be a HUGE Difference in Terms of Noise.You can replace it with a lower rpm blower or with regular 40mm fans for less than adding seperate fans in the rear tho.
The noise depends on what fans you go with for either option, neither of them has to be loud.Well, 3 x 40mm each Server (1U) isn't much different than 3 x 120mm each 3U in Terms of Cost. But it will likely be a HUGE Difference in Terms of Noise.
Why ?But its not like you can just remove the blower and get good airflow with only pulling air in rear of rack either.
You are looking at placing atleast 1 fan in the case regardless.
FS.com offers 10x blank plates for ~80US$ in a package. They are tool-less. Super easy to use. Not sure if you can print 10 for 80 incl fast shipping.I'll just do an Order using CraftCloud for ~30 Pieces of that IO Shield (I'll see if I can get it printed in Metal Sheet, might be way too expensive though), as well as some other Stuff I could 3D Print as well.
Last Time i went with a Belgian Company that was the Cheapest and the Results were "OK" I would Say. Since it was some SSD Caddies and it wasn't a huge premium, I went with 40% Fill instead of the "Standard" 20%, hopefully to make them a bit more sturdy.
EDIT 1: I don't have a 3D Printer, that's why I go with CraftCloud
EDIT 2: I ended up buying 26 of the Chassis CSE-512
EDIT 3: For Cooling I'm honestly considering (hence why I want to mount the Chassis Rack Ears in Reverse, so I can have all Connections and Ears on one side and I shouldn't even need to use the Front Panel Anymore) to put a bunch of external 120mm or 140mm (better) Fans all on one Side of the Chassis, by using something like this to mount them

latest version is on printables.com@dbram: what's the Status on the IO Shield, does it work as expected with your latest Changes ?
What were the Issues (before the Changes you made ?), something about the Screw Holes not working properly ?
The asrockrack board b450d4u-v1lq5 is beig sold at a very good price some cases were needed. had some supermicro CSE512 left over, combine them, started from the very identical board x470d4u (that has more connectors).
todo's:
the thickness of the shield is ok.
- no holes yet for screws. : fixed in v1.5
- the connectors at the bottom need to be slimmer, fixed in v1.5
- the margin around the vga connector needs to be increased fixed in v1.5
- add opening for the top case cover clip : fixed in v1.5
good question, a usb-hub with 4 hdmi captures is feasable, but adding 4x benfei is not cheap, 9-12 eur each. it almost doubles my total cost (per 4 nodes).Do you think the extra complexity of the VGA/HDMI Switch is worth it though ?
that's also possible of course.EDIT 1: why LXC and not Docker/Podman Container though ?
If I'm understanding you correctly, you want to mount a bunch of 120mm fans on the outside of the chassis, 3 of them per 3 servers?Why ?
As long as the external Fan has enough Static Pressure (at the required Airflow Operating Point) and there are no Bypass paths (i.e. if a Server is not installed, then a 1u Plug / Blank is installed instead), all Air should be able to flow through the Chassis ...
But I'm all ears if you have suggestions for cheap, good and quiet 40mm Fans![]()
