I see they forgot the IO Shield. A common mistake, both for beginners and experts.

My last couple of mobos have had them built-in, which I love so much it makes me wonder why they didn't start doing it sooner.

atomicbocks@sh.itjust.works · 15 pts · 57d (3 replies)

Back in the day there was no backplane and the only port on the mobo was the AT keyboard port so that was the only hole in the case. The rest were punchouts for parallel and various serial ports that would be connected to the mobo via ribbon cable. When the first ATX mobos came out they kept the punchouts for the backplane but that required all the manufacturers to use the same port layout so that lasted all of like 2 years before the pop-in shield became the norm.

How are the new ones getting around the different port layouts?

The shield is built into the mobo, not the case. Same footprint as the ones you insert into the case (before the mobo, but dont accidentally bend the spacer tabs and lose access to the Ethernet port) but without the ADHD getting in the way.

atomicbocks@sh.itjust.works · 3 pts · 57d

Speaking of ADHD getting in the way, despite the previous commenter saying mobo I was still imagining it the other way around. That makes way more sense.

(Ugh, the number of times I’ve cut myself trying to get the Ethernet shield out of the way)

That's a funny way of spelling "slicing the fuck out of your finger and having to take a 2-day break from the build because your fine motor skills are shit with a band-aid on".

What exactly does the shield do?

lime@feddit.nu · 27 pts · 57d (2 replies)

stops airflow

LodeMike@lemmy.today · 15 pts · 57d (1 reply)

Ah yes managing airflow is a huge priority with this build.

lime@feddit.nu · 9 pts · 57d

i thought that was the entire point

HerbalGamer@sh.itjust.works · 20 pts · 57d (2 replies)

Keeps the I's O.

SatansMaggotyCumFart@piefed.world · 11 pts · 57d

I thought it shielded the I's and O's to keep them separate.

LodeMike@lemmy.today · 6 pts · 57d

But what keeps the O's I??

atomicbocks@sh.itjust.works · 11 pts · 57d (3 replies)

Real answer: it serves two purposes. First it ties the ground shielding from the ports to the grounding plane of the case itself so that static discharge is dissipated there rather than the motherboard. Second it completes the RF shield created by the case, this was way more important in earlier in computing and is also required to comply with that FCC rule about not interfering with other devices that you see printed on the bottom of things still sometimes.

So.. Neither is missing from this case. Ain't no shielding happening on this plastic-coated beast

atomicbocks@sh.itjust.works · 7 pts · 57d (1 reply)

As long as it’s plastic coated metal it should still be capable of shielding any wavelength larger than the squares. So you would still need to put your WiFi antenna on the outside I think.

Mnem667@retrofed.com · 6 pts · 57d

You know, that's fair. And I suppose that covers radio, so...

cRazi_man@europe.pub · 5 pts · 57d

It is the underwear for the PC. The PC's nethers will be left uncovered. Although that might be intentional in this case since some people like the breeze in their nethers.

It ain't tho

Buddahriffic@lemmy.world · 35 pts · 57d (4 replies)

Yeah, it's like the difference between sitting in a stopped car with all the doors open vs sitting in a moving car with the front driver and rear passenger windows open. The first one might feel cooler on a windy day, if the wind is blowing in the right direction, but the other will have consistent airflow from the outside through the car and back outside.

tomiant@piefed.social · 11 pts · 57d

Trust the metal cages. Metal cages are very mature technology.

alanjaow@lemmy.world · 5 pts · 57d (2 replies)

I prefer using the opposite windows. I don't like a breeze directly at my face.

Dozzi92@lemmy.world · 4 pts · 56d

I keep my sunroof open and the back passenger side window cracked. It is the optimal airflow for the driver's seat. I couldn't tell you what the rest of the seats feel like, but those are of no concern to me.

Indeed, there's a reason we have all sorts of ducting, we want the air to flow specific ways. Not so great when hot air could easily recirculate immediately back to intake.

This is pretty sweet for a home-made, budget case.

A_Union_of_Kobolds@lemmy.world · 30 pts · 57d

Could probably use some filters at least tho

OwOarchist@pawb.social · 21 pts · 57d (4 replies)

Not bad, actually. I'd kind of like to see a more professionally engineered case like this, with proper mounting points for the hardware instead of zip ties. (Oh, and a more easily opened side panel.)

May have some dust issues, yes, but could potentially be cleaned with compressed air without even needing to open the case. And you really do get massive airflow potential. And it's relatively lightweight!

Lucidlethargy@sh.itjust.works · 11 pts · 56d

Ideally you'd want to push all the heat out in one direction, two if you must. A case like this world spit heat out in most directions, which may pull it right back in.

I think it’s neat, I actually like the weird almost vapor wave aesthetic

wabafee@lemmy.world · 5 pts · 56d

Cheap also to cool just need a standard electric fan than any aftermarket cooling out there which are overly expensive in my opinion.

If you have ever seen a cooler master HAF XB EVO it's pretty much this but horizontal.

I felt a convulsing shudder roll up my innards, complete with subtle eye twitch at the peak, like a cherry on top, when I read your comment.

Surely normal cases have some kind of ducting considerations to pull airflow through more effectively?

Chronographs@lemmy.zip · 3 pts · 57d

An open case like this will generally be the coolest, the reasons you don’t do this are dust, noise, and just generally protecting the components.

smh@slrpnk.net · 2 pts · 56d

It's been a while since I read that classic of heat transfer Hot Air Rises and Heat Sinks, but I'd worry about pockets of air getting stuck around important computer components. Like, sure there's a lot of air going past things on average, but not necessarily around the things that get the hottest.
