ladies and gentlemen children of all ages we are back with part two of our
hack pro build and in front of me you can see the case is torn apart and
in other exciting news we've also got
this this is the adapter that we're gonna
need to install our motherboard into
this chassis so today's plan is to install the motherboard tray make sure
we got our measurements correct guys we're gonna need every millimeter we can
get in this build and then make the adapter plate for the back of the case
which is going to go in there
before we do that though we're going to show you how we got to this point by
taking apart ah here it is this oh it's so heavy

before we get started on our teardown we need to make sure that all of our
hardware still works after everything we've done to it you know removing the
heatsinks and stuff and that it boots into macOS
that's why they're all there ah thank you that
could have been really bad
it's on i don't see any power going to the board though yeah like nothing's
lighting up it just works i don't always take a drink of water
while i wait for my computer to boot but when i do it's from Linus tech tips
water bottle and we're in it's a mac pro
6.1 running macOS 10.14.5
384 gigs of RAM and we've got 28 CPU
cores we do have one problem though and we were kind of worried about this so if
we open up disk utility we can see that only one
of our 950 pro ssds that we're using to test our quad m.2 pci express card here
is being detected so in order for these
16x to four times 4x slot adapters to work you
need a feature called pci express bifurcation which not all motherboards
support it's more common in the server space so that's not working which means
we might need to reevaluate our storage but we can still move forward for now
now don't worry guys before you freak out this is not a working specimen we
got this from free geek thanks free geek by the way
but even so you're going to want to go slowly
and be careful
you don't want to risk accidentally damaging anything that does work
okay that's how we remove the cpus i remember
try blade fans these are thick too these are 38
millimeter thick fans looks like whoever uh whoever's mac this was did some
upgrading so we've got some Corsair value select we've got some hyper
velocity premium apple that looks very premium and apple certified right there
got some kingston memory some more value select well now that we've kind of gone
down this path we might as well continue with it so there's our wireless card
airport extreme
we won't need this mid plate so we can go ahead and
ah one sec
here's our last cooling fan so that's an 80 ml cooling fan as well as
wow that is a shockingly beefy built-in
case speaker
oh yeah pci express
holy crap no it isn't i just assumed this is an agp graphics card what the
crap why would they design it like that everything is designed to be
straightforward okay so i think we're at the point now where we're ready to slide
the board but it looks like these standoffs need
to come out so we could unscrew them or
just yeah give it a little
ah feels like when i was having my wisdom teeth removed
i'm sure all the seasoned mac technicians out there are like well
lol um actually look i've never taken one of these apart
before okay and in my defense they don't exactly
make it intuitive everything is designed to be straightforward
yeah get get one go on get
get cool so on the back we've got all these
uh rubber spacers uh this looks like the
uh CPU chipset so that would be like your northbridge south bridge probably i
mean i'm guessing just based on having seen a fair number of motherboards no
such corners were cut on the ecs a55f
dash m4 1.0 and there's our i o that we don't need anymore oh hey look the specs
are on here so this was a two gigahertz dp
dual processor get your mind out of the gutter
512 megs ddr 400 megahertz 160 gig
has an sd reader g5200 would that be the graphics card
no do you feel maybe that's like the model do you i'm not sure 56k modem pci
x let's get that dang it let's get this power supply out of here now this i want
to be careful with because i don't know if there's any exposed
nonsense in here that is a chunky
power supply holy smokes five that's a 500 watt power supply
wow power supplies have come a long way you know you might think oh like older CPU
tech might be like really huge or whatever actually that's it
that's one of the processors from the power mac g5
ibm power processor right there right so i could finish this off pull
the optical and the hard drive out with all the quick clips and all that kind of
stuff and then we'd actually have to cut some of these other components out
but why bother doing that
when this unit is already prepped now as
you guys saw apple didn't use anything
that i would describe as pc standard when it came to their motherboard design
so that's where here it is this motherboard tray comes
in so the next thing we're going to do is show you guys how we're going to
adapt that non-standard layout to our hptx motherboard before we put that in
though let's talk about one of the other things that we had to deal with here so
if you guys remember the i o which is completely unlike pcio was in the back
here so that's all been chopped out but we did manage to retain the original
locking mechanism which we are hoping to continue to use so i'm just going to go
ahead and pop this back into place
now let's throw in our motherboard tray so one of the benefits of doing an
adapted motherboard tray versus just putting new standoffs in here is that we
actually needed some space behind the motherboard in order to route our cables
anyway so this has it lifted up ah man about it about a
centimeter and change above the bottom here and we can use that for all the
routing that we need to do we know it's not very pretty right now guys
there's still a lot of work to be done this is just mostly to do a
a more thorough test fit so there's no shortage
of g5 mac back adapter plates but this
one is going to be a little bit different so instead of just kind of bolting onto
the back and sticking out we want it as close to a factory finish as we can get
once we finish painting so what we've done here is we've got a cut out for our
pci slots our dual 120 millimeter fans which are
gonna have a radiator on them our pc i o plate here and then check this out
there's double-sided tape on these lips here so to get this in we've got these
little slides cut in the original case here
and then you kind of fight with it a bit
yep oh shoot i missed one sec
don't worry we're going to be painting it so if we get some little scratches on it
and stuff we're not going to consider that the end of the world
oh
so there's some spots where there's clearly still a bit more material that
needs to be taken out we've got a bit of a lip here around the
um around the side panel locking mechanism
but there's other spots where we are pretty darn close by the
time we take this piece here put in some
perforations just like the metal from the factory put in some filler here sand
it down and paint it you would be hard pressed
to notice that this is not supposed to be here
i know what we're doing right now doesn't look like much but this is very
moment of truth for this project guys because there's a lot of
redoing of fab that will need to be done if this does not
fit so the motherboard tray is right up
against our back adapter plate here and
it looks like the screw holes are in fact going to line up but the only way
we're going to know for sure is to put these in we're going to be using the
shortest ones that we can possibly find because unlike the back of our
motherboard tray where we're planning to do some cable routing we do not want to waste any space
between the motherboard tray and the motherboard that we don't have to
you know the crazy thing is is it's not even that unreasonable
looking compared to the original one
we've got to be careful with this board i don't think Gigabyte's sending us another one now that they know what
we're doing with it maybe i called it a success too early
these standoffs are pretty tight okay i got that one
and yes we're gonna round this off don't worry you guys
so as we've done before we just harvested uh pci slot holders from an
existing case now this isn't actually it doesn't have the slot for it to come through yet but
it's gonna go in kind of like that and then we're going to have our our
dual fan radiator here in the back but let's go
ahead and throw the cards in without that for now
oh yeah wow it goes oh not bad
okay so obviously our graphics card's sagging
a little bit right now but this radiator
is gonna go right here
oh it's looking a lot more real ladies and
gentlemen there it is
we're going black fans right yeah yeah yeah okay
all right so we've got our power supply and that's not actually the way it's going to go in it's going to be tilted
up but right now this CPU heatsink is in the way it's going to be a water block
later and go ahead and put our triple radiator back in
that fits just right doesn't it i'm willing to bet a lot of you didn't have
