you don't really do case reviews anymore because well if we're being honest they
have really changed much lately other
than some tempered glass here and some RGB there but that's not the case with
this one this is the Silverstone mammoth mm oh
one a spectacularly heavy black monstrosity
whose claim to fame it's been really
difficult to open the box up is being bust proof and splash proof some things
are about to get wet
literally we're gonna spray water on a
system in this case with an extreme edition processor running inside it but
you know what we're not gonna spray water on Brandon because he deserves better than
that even if he did bung up the audio settings the first time we shot this
Corsairs obsidian 500d mid-tower gaming
case features premium tempered glass and aluminum construction removable top fan
trays and more check it out at the link below this thing actually launched all
the way back in 2015 completely flying under my radar due to
its unprecedented level of neatness so you
could think of the mammoth as kind of like the
off-road edition of what would normally
be a computer case like designed for use
in rough conditions oh
you know it's actually not that crazy
big but it's really heavy oh my gosh
that's pretty brutal it is kind of got a plane
sort of look to it there's no tempered glass that's pretty nice that's magnetic
yeah the exterior is about as plain black box
as you can get it sports a brushed steel finish but in the age of tempered glass
Windows you'd be forgiven for thinking it's a little boring but if you look a
little closer the entire top of the case is completely filled right so no IO or
fan holes whatsoever up here to keep
water from getting in presumably and check out these so this is cool these
front louvers are not an aesthetic feature instead they actually serve to
prevent fluids again from getting to the internal components of the PC and
flipping it around to the back you can see it has the same louvers here with a
notch at the bottom check that out to
allow you to get cables to the rear i/o the design of the mammoth gives it an
impressive IP 43 rating meaning it's
safe from not just drips like if you were to spill a cup of water onto the
table next to it but even water sprays
now I wouldn't recommend pressure washing your computer and gaming at the
same time but if you left a window open with the sprinkler running your computer
should be okay it's just the rest of the room I'd be concerned about let's crack
it open yeah
here we find the MMO one second party
trick a full fat 20 millimeter thick HEPA filter now most fan filters are
pretty good at mitigating dust buildup over the short term but a filter like
this is SPECT to remove 99.97% of
particles larger than 0.3 microns that's
smaller than all but the smallest bacteria so I guess you won't have to
worry about your PC getting the flu obviously compared to a regular filter
this one's gonna be a little more restrictive right but it looks like
Silverstone thought of that because they not only have to push air through one
just like that but also the HEPA filter and the solution these babies to
massive 180 millimeter air penetrator
fans at max speed which you can control with these knobs at the front these move
a whopping 340 CFM of air about the same as a
typical pedestal fan at medium pretty darn impressive then to top it off
there's actually space to install a rear 120 millimeter fan as well so while Jake
builds up a high-end system for our tests let's get a little bit of
preparation done
okay it's done you want to see yeah let's have a look
alright so there are a few things that stand out
a lot of cases these days are basically just
the standard layout with a different
bezel on the front not so here so first
of all the layout is inverted so the CPU is on the bottom and the GPU is on top
second our power supply actually takes a
page out of 2006's book and is up on the
top but still with no ventilation that's
because the whole top was sealed to keep water from getting in so the power
supply actually has to suck air from the inside then blow it out the back
fortunately these fans that we showed you guys at the front should keep it
well supplied with fresh air all take a
moment here to show you guys this here CPU heatsink support thing so there's
actually wonderful at the graphics card and the CPU which if you think about the
applications in this case on let's say something like a boat makes a ton of
sense cuz if this pcs are rocking you
don't want your heatsink going and knocking about on the inside
because of the design of the filtering system nearly 40% of the space inside
the case is taken up by the filter in the front and the buffer in the rear to
prevent water from entering the system it does limit your cooling options but
even with the relatively limited space the MMO one can still fit for dual slot
graphics cards and easily houses up to an SSI EEE be dual socket motherboard if
you're willing to limit your storage expansion to two three and a half inch
drives so this is all good in theory but we want see what kind of thermals we
might expect with a high-end system in this case so you want to throw the panel
on there and I'll get a stress test fire it up here it's actually kind of amazing
how much air these fans move through that HEPA filter yeah I mean they are a
max speed rather than leave it at these
settings though like this is quite loud I want to go with not minimum but quiet
enough that it probably wouldn't bother anyone
that seems pretty good and we're still getting like quite a bit of airflow back
here let's give it some time to heat up yeah okay so these are not bad results
actually GPU is tearing up to 17 80 or
so at its 82 degree maximum and our CPU has only two cores about sixty degrees
three not too shabby yeah I mean there's an NHD 15 in there so CPU temperatures
are probably expected are you ready to run it through the gauntlet yeah let's
do it all right so we're here we're gonna do the gauntlet lioness is a
little busy with another video and I definitely am NOT doing this for the
second time no this has never done this test before oh this looks Turner on get
these fans to chin so there might be a little bit of dust in there but I kind
of have an idea of how much was in there beforehand just like throw a little dust
on there here nice and not nice I guess I don't know I
really hope we don't have to do this again because I do not have any dust
left all right so there's actually quite a
bit of dust up here I'm not really sure how that got in there okay so let's
let's turn it off this time and see what's going on inside I think for the
most part it's gonna be pretty decent but I imagine there's going to be some
leakage all right
so that is a little more dust than was in
there before so I don't think this system is perfect but it actually held
up pretty good regular computer dust is not gonna be an issue for this thing
maybe don't throw sawdust at it or use it in your woodshop okay so let's see
how the filters doing oh no that's gross
oh so the attacked side is pretty
disgusting but when we flip it over
pretty damn clean so it looks like a
little bit of dust got in but I imagine it's probably just from the cracks
around I don't think dust that big would get through a filter like this
and then on this side pretty dirty here
as well alright let's get to the water oh
my god you think I should spray with a hose - I
think we should spray it with those alright I
should probably turn it on before we spray it with the hose
is it on Oh
I really hope this survives my test bench actually
it would be really inconvenient if this died
I'd be kind of upset to be honest
there's a little water in there but for the most part it looks like it's dry Wow
Wow completely dry inside sure there's a
little water around the edges but inside the computer there's no moisture I think
we should probably test this before I bring Linus over you know just in case
it doesn't work display for
this monitor even plugged in oh my gosh
oh yeah it works okay let's let's get Linus
and show them the carnage so to be honest I already opened it
there is a little bit of dust in there no water no water I sprayed this thing
down good
this side is a little beat-up yeah I see
that Wow but it caught it yeah so yeah
there's a little bit of dust on the panel there and you can see some of the
chunks did make it through but I mean
compared to what you'd see in a normal case
that is really impressive I think my
dust abuse is a little out of the ordinary as well yeah no I mean this is
obviously a torture test but you can see even where the water did manage to
penetrate the design doesn't allow it to
go any further than this yeah there's a little splash shield here
too oh so
it doesn't have the greatest cooling characteristics out of any case we've
ever tried but it's utterly unique in its dust and
water resistant design making it at what
is it three hundred bucks basically a no-brainer if you need a
dust and water resistant PC case
