Do you need to cut grommets (as per manual) in O11XL for all EATX boards? (or just some)

As the title suggests
There's a page in the O11 XL Manual that depicts trimming down the 3 rubber grommets on the right-hand side of the motherboard, "to install a special spec MB (ex MB including a LED module and/or thicker shield)".

Bit hard to tell if this applies to all EATX boards?

My Asrock X99 covers 50% of the grommets. It's possible I suppose, that routing cables through those grommets, could cause the rubber of the grommet flaps to contact the underside of the motherboard (which is PCB, this board is older than the current trend of fully-shielded/shrouded boards).

Being rubber I would not think this is a big deal and I kind of don't want to trim them.

Anyone who has built with EATX in the O11 XL, can you help me out please? Trim or not trim?

Cheers

If the board fits and screws in then it is fine. The grommets won't damage anything. If it is like my O11 Air Mini you can also pop the grommets out of the hole.

Hi,
I've never seen them so large or thick they'd need to be cut frankly
Post an image.

Mother board standoffs must be very short ?

My clearance seems fine, standoffs are tall enough, it's the manual that comes with the XL that suggests cutting the grommets down. It's not clear what they mean my "special spec MB".
I went looking on Youtube for any build walkthroughs using the O11 XL, and saw a bunch where the EATX overlaps the grommets and they just left the grommets alone.
Sooooo hopefully I am OK and I don't fry something. :)

There is no need to cut the grommets, you can simply squeeze them in the middle, and they should come clean off. If they're of the same kind that are used on the O11 Air, that is...

I've installed a large board in my Corsair case and some grommets are covered, though this isn't an issue since I'll only route a couple of cables. But it won't cause any troubles, they're rubber after all.

Not sure why the manual would suggest destroying part of a case to fit a motheboard. Strange.

Might be because of some new models of motherboard that have thick metal shrouds all over them, which may actually collide with the thicker rubber grommets.
I was more wondering if it was going to be a safety or heat issue at all with my EATX (but older, bare PCB x99 mobo, no fancy shrouding) contacting.
My (again older) PSU cables are pretty fat so they might bend the rubber flaps upwards.

It's just that the manual isn't super clear on what exact scenario those instructions apply to. It's one of those manuals that is more pictures and diagrams than words. Open to interpretation... plus lost in translation!

They just gave the warning since at least one board out there requires it

Hi,
Yeah some mobo's do come with metal back plates
I haven't noticed any lately but my x99 sabertooth has one

But general rule is if the standoffs are taller you shouldn't have any issues
Don't think rubber has ever fried anything unless it was wet :laugh:

While I do not own this specific case (I own an O11D Mini though) I would leave the grommets intact unless one or more were impending on motherboard installation and/or function and trim as necessary.

I don't think Lian Li is instructing owners to cut down the grommets unnecessarily but only if the situation calls for it.

Oh, and I think they're silicone not rubber.

System is running fine with grommets intact, even though my PSU cables are fat and displace the rubber flaps a lot. No issues with back of PCB contact.
So all clear here. :) Thanks everyone for chiming in, appreciate it.

Over time the flaps may break off though. They did on my O11 Air. But it's no big deal :p

Enjoy, cheers

TUF hasn't had the military hardened thematic for a long time, and just shifted to a budget-friendly brand below ROG Strix and the core ROG series (true high-end). Only the Haswell generation came with the metal backplate, Z87 and X99, the Z97 through Z270 offered it as an optional (had to buy Mark 1 submodel), and with the Z370 onwards (or for the last 5 years or so), this isn't an option anymore. It's a shame, because this an excellent thing that they had going, but it's ancient history now.

My case has cross hatch grommets, the cables go through and do the same thing, as long as the cables dont vibrate around you will not get chaffing in them, so just enjoy the rig.

Hi,
Warranty has always been the biggest difference between tuf and strikes/ prime.. which are both bloated/ bling crap series boards
TUF has always had 5 years verses shit standard 3 years on the other bling series you say is some how "true high end" lol think you're confused the high end is ROG the prime/ strikes is main stream suckers series :laugh:

TUF is asus budget lineup these days, for sure
They're all price point budget series now days not just the tuf others just have more bling and bloat.
