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

[-] bitjunkie@lemmy.world 43 points 1 month ago

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 points 1 month ago

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?

[-] DarkSirrush@piefed.ca 12 points 1 month ago

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.

What exactly does the shield do?

[-] lime@feddit.nu 27 points 1 month ago
[-] LodeMike@lemmy.today 15 points 1 month ago

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

[-] lime@feddit.nu 9 points 1 month ago* (last edited 1 month ago)

i thought that was the entire point

[-] HerbalGamer@sh.itjust.works 20 points 1 month ago
[-] SatansMaggotyCumFart@piefed.world 11 points 1 month ago

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

[-] LodeMike@lemmy.today 6 points 1 month ago

But what keeps the O's I??

[-] atomicbocks@sh.itjust.works 11 points 1 month ago

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.

[-] Mnem667@retrofed.com 6 points 1 month ago

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

[-] atomicbocks@sh.itjust.works 7 points 1 month ago

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 points 1 month ago

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

[-] cRazi_man@europe.pub 5 points 1 month ago

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.

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 points 1 month ago* (last edited 1 month ago)

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

[-] alanjaow@lemmy.world 5 points 1 month ago

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

[-] Dozzi92@lemmy.world 4 points 1 month ago

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.

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

[-] A_Union_of_Kobolds@lemmy.world 30 points 1 month ago

Could probably use some filters at least tho

[-] OwOarchist@pawb.social 21 points 1 month ago

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 points 1 month ago

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.

[-] CultLeader4Hire@lemmy.world 7 points 1 month ago

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

[-] wabafee@lemmy.world 5 points 1 month ago* (last edited 1 month ago)

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

[-] tempest@lemmy.ca 3 points 1 month ago

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

That's some vintage hardware there too.

I'd still rest my coffee on the top. I like to live dangerously.

[-] MrOtingocni@lemmy.world 5 points 1 month ago

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.

Gonna collect all kinds of dust and grime.

[-] Cellari@lemmy.world 3 points 1 month ago

Next step, design intakes so we can put dust filters there

[-] Signtist@bookwyr.me 8 points 1 month ago

Forgot to tape one of those big box fans to the side.

"Who's your favorite cooling brand? Corsair? BeQuiet? Noctua?"

"...Lasko."

[-] Philharmonic3@lemmy.world 6 points 1 month ago

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

[-] Chronographs@lemmy.zip 3 points 1 month ago

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.
