00:00:00.000 --> 00:00:05.359
ladies and gentlemen children of all ages we are back with part two of our

00:00:03.760 --> 00:00:12.320
hack pro build and in front of me you can see the case is torn apart and

00:00:09.280 --> 00:00:13.440
in other exciting news we've also got

00:00:12.320 --> 00:00:19.199
this this is the adapter that we're gonna

00:00:15.759 --> 00:00:22.080
need to install our motherboard into

00:00:19.199 --> 00:00:25.920
this chassis so today's plan is to install the motherboard tray make sure

00:00:24.080 --> 00:00:30.400
we got our measurements correct guys we're gonna need every millimeter we can

00:00:28.000 --> 00:00:34.880
get in this build and then make the adapter plate for the back of the case

00:00:32.960 --> 00:00:37.840
which is going to go in there

00:00:36.079 --> 00:00:42.960
before we do that though we're going to show you how we got to this point by

00:00:41.280 --> 00:00:48.239
taking apart ah here it is this oh it's so heavy

00:00:46.960 --> 00:00:50.960
power mac g5

00:00:54.960 --> 00:01:00.879

00:01:11.040 --> 00:01:17.930
LTT

00:01:20.960 --> 00:01:25.920
before we get started on our teardown we need to make sure that all of our

00:01:24.000 --> 00:01:30.880
hardware still works after everything we've done to it you know removing the

00:01:28.240 --> 00:01:34.320
heatsinks and stuff and that it boots into macOS

00:01:32.320 --> 00:01:38.479
that's why they're all there ah thank you that

00:01:35.520 --> 00:01:38.479
could have been really bad

00:01:38.560 --> 00:01:44.799
it's on i don't see any power going to the board though yeah like nothing's

00:01:41.920 --> 00:01:47.759
lighting up it just works i don't always take a drink of water

00:01:46.159 --> 00:01:52.880
while i wait for my computer to boot but when i do it's from Linus tech tips

00:01:49.680 --> 00:01:55.640
water bottle and we're in it's a mac pro

00:01:52.880 --> 00:02:02.240
6.1 running macOS 10.14.5

00:01:57.320 --> 00:02:04.640
384 gigs of RAM and we've got 28 CPU

00:02:02.240 --> 00:02:08.879
cores we do have one problem though and we were kind of worried about this so if

00:02:06.399 --> 00:02:13.599
we open up disk utility we can see that only one

00:02:10.720 --> 00:02:19.680
of our 950 pro ssds that we're using to test our quad m.2 pci express card here

00:02:17.840 --> 00:02:23.280
is being detected so in order for these

00:02:21.599 --> 00:02:27.840
16x to four times 4x slot adapters to work you

00:02:26.319 --> 00:02:31.440
need a feature called pci express bifurcation which not all motherboards

00:02:29.599 --> 00:02:36.400
support it's more common in the server space so that's not working which means

00:02:34.000 --> 00:02:40.319
we might need to reevaluate our storage but we can still move forward for now

00:02:38.640 --> 00:02:44.480
now don't worry guys before you freak out this is not a working specimen we

00:02:42.319 --> 00:02:48.080
got this from free geek thanks free geek by the way

00:02:45.920 --> 00:02:51.080
but even so you're going to want to go slowly

00:02:52.319 --> 00:02:55.360
and be careful

00:03:00.000 --> 00:03:05.840
you don't want to risk accidentally damaging anything that does work

00:03:07.040 --> 00:03:12.879
okay that's how we remove the cpus i remember

00:03:11.200 --> 00:03:17.760
try blade fans these are thick too these are 38

00:03:15.040 --> 00:03:21.519
millimeter thick fans looks like whoever uh whoever's mac this was did some

00:03:19.920 --> 00:03:26.800
upgrading so we've got some Corsair value select we've got some hyper

00:03:24.159 --> 00:03:31.440
velocity premium apple that looks very premium and apple certified right there

00:03:29.440 --> 00:03:34.959
got some kingston memory some more value select well now that we've kind of gone

00:03:33.280 --> 00:03:40.879
down this path we might as well continue with it so there's our wireless card

00:03:37.760 --> 00:03:42.799
airport extreme

00:03:40.879 --> 00:03:46.200
we won't need this mid plate so we can go ahead and

00:03:54.799 --> 00:03:58.560
ah one sec

00:03:58.879 --> 00:04:06.000
here's our last cooling fan so that's an 80 ml cooling fan as well as

00:04:02.480 --> 00:04:08.130
wow that is a shockingly beefy built-in

00:04:06.000 --> 00:04:10.640
case speaker

00:04:10.640 --> 00:04:16.639
oh yeah pci express

00:04:14.480 --> 00:04:21.600
holy crap no it isn't i just assumed this is an agp graphics card what the

00:04:18.880 --> 00:04:24.720
crap why would they design it like that everything is designed to be

00:04:22.800 --> 00:04:27.440
straightforward okay so i think we're at the point now where we're ready to slide

00:04:26.400 --> 00:04:33.600
the board but it looks like these standoffs need

00:04:29.680 --> 00:04:34.800
to come out so we could unscrew them or

00:04:33.600 --> 00:04:37.759
just yeah give it a little

00:04:38.400 --> 00:04:43.840
ah feels like when i was having my wisdom teeth removed

00:04:46.720 --> 00:04:53.280
i'm sure all the seasoned mac technicians out there are like well

00:04:50.720 --> 00:04:57.120
lol um actually look i've never taken one of these apart

00:04:55.199 --> 00:05:01.040
before okay and in my defense they don't exactly

00:04:59.199 --> 00:05:04.080
make it intuitive everything is designed to be straightforward

00:05:05.520 --> 00:05:11.840
yeah get get one go on get

00:05:09.600 --> 00:05:18.320
get cool so on the back we've got all these

00:05:14.160 --> 00:05:20.400
uh rubber spacers uh this looks like the

00:05:18.320 --> 00:05:24.880
uh CPU chipset so that would be like your northbridge south bridge probably i

00:05:22.400 --> 00:05:31.759
mean i'm guessing just based on having seen a fair number of motherboards no

00:05:27.039 --> 00:05:34.639
such corners were cut on the ecs a55f

00:05:31.759 --> 00:05:38.160
dash m4 1.0 and there's our i o that we don't need anymore oh hey look the specs

00:05:36.479 --> 00:05:41.440
are on here so this was a two gigahertz dp

00:05:39.840 --> 00:05:49.360
dual processor get your mind out of the gutter

00:05:44.240 --> 00:05:51.479
512 megs ddr 400 megahertz 160 gig

00:05:49.360 --> 00:05:56.880
has an sd reader g5200 would that be the graphics card

00:05:54.960 --> 00:06:01.520
no do you feel maybe that's like the model do you i'm not sure 56k modem pci

00:06:00.400 --> 00:06:06.479
x let's get that dang it let's get this power supply out of here now this i want

00:06:04.960 --> 00:06:11.440
to be careful with because i don't know if there's any exposed

00:06:08.240 --> 00:06:13.680
nonsense in here that is a chunky

00:06:11.440 --> 00:06:17.680
power supply holy smokes five that's a 500 watt power supply

00:06:16.880 --> 00:06:23.759
wow power supplies have come a long way you know you might think oh like older CPU

00:06:22.400 --> 00:06:28.319
tech might be like really huge or whatever actually that's it

00:06:26.800 --> 00:06:32.960
that's one of the processors from the power mac g5

00:06:30.160 --> 00:06:36.240
ibm power processor right there right so i could finish this off pull

00:06:34.639 --> 00:06:40.639
the optical and the hard drive out with all the quick clips and all that kind of

00:06:37.919 --> 00:06:46.560
stuff and then we'd actually have to cut some of these other components out

00:06:43.120 --> 00:06:50.319
but why bother doing that

00:06:46.560 --> 00:06:53.360
when this unit is already prepped now as

00:06:50.319 --> 00:06:56.240
you guys saw apple didn't use anything

00:06:53.360 --> 00:06:59.520
that i would describe as pc standard when it came to their motherboard design

00:06:58.160 --> 00:07:05.360
so that's where here it is this motherboard tray comes

00:07:03.440 --> 00:07:09.759
in so the next thing we're going to do is show you guys how we're going to

00:07:07.360 --> 00:07:13.680
adapt that non-standard layout to our hptx motherboard before we put that in

00:07:12.400 --> 00:07:18.319
though let's talk about one of the other things that we had to deal with here so

00:07:15.599 --> 00:07:24.400
if you guys remember the i o which is completely unlike pcio was in the back

00:07:21.520 --> 00:07:28.479
here so that's all been chopped out but we did manage to retain the original

00:07:26.400 --> 00:07:34.880
locking mechanism which we are hoping to continue to use so i'm just going to go

00:07:30.720 --> 00:07:34.880
ahead and pop this back into place

00:07:36.960 --> 00:07:43.039
now let's throw in our motherboard tray so one of the benefits of doing an

00:07:40.400 --> 00:07:47.039
adapted motherboard tray versus just putting new standoffs in here is that we

00:07:45.360 --> 00:07:51.440
actually needed some space behind the motherboard in order to route our cables

00:07:48.720 --> 00:07:57.360
anyway so this has it lifted up ah man about it about a

00:07:54.639 --> 00:08:01.840
centimeter and change above the bottom here and we can use that for all the

00:07:59.759 --> 00:08:06.160
routing that we need to do we know it's not very pretty right now guys

00:08:04.160 --> 00:08:10.000
there's still a lot of work to be done this is just mostly to do a

00:08:08.879 --> 00:08:16.400
a more thorough test fit so there's no shortage

00:08:13.280 --> 00:08:17.919
of g5 mac back adapter plates but this

00:08:16.400 --> 00:08:23.599
one is going to be a little bit different so instead of just kind of bolting onto

00:08:21.680 --> 00:08:27.440
the back and sticking out we want it as close to a factory finish as we can get

00:08:25.840 --> 00:08:32.320
once we finish painting so what we've done here is we've got a cut out for our

00:08:30.800 --> 00:08:37.360
pci slots our dual 120 millimeter fans which are

00:08:34.399 --> 00:08:42.080
gonna have a radiator on them our pc i o plate here and then check this out

00:08:39.919 --> 00:08:46.959
there's double-sided tape on these lips here so to get this in we've got these

00:08:44.720 --> 00:08:50.560
little slides cut in the original case here

00:08:47.760 --> 00:08:56.800
and then you kind of fight with it a bit

00:08:53.200 --> 00:08:58.160
yep oh shoot i missed one sec

00:08:56.800 --> 00:09:02.800
don't worry we're going to be painting it so if we get some little scratches on it

00:09:00.800 --> 00:09:09.000
and stuff we're not going to consider that the end of the world

00:09:06.000 --> 00:09:09.000
oh

00:09:15.440 --> 00:09:20.720
so there's some spots where there's clearly still a bit more material that

00:09:18.880 --> 00:09:24.080
needs to be taken out we've got a bit of a lip here around the

00:09:23.120 --> 00:09:28.080
um around the side panel locking mechanism

00:09:26.399 --> 00:09:34.399
but there's other spots where we are pretty darn close by the

00:09:31.279 --> 00:09:36.080
time we take this piece here put in some

00:09:34.399 --> 00:09:41.040
perforations just like the metal from the factory put in some filler here sand

00:09:38.880 --> 00:09:44.240
it down and paint it you would be hard pressed

00:09:42.000 --> 00:09:46.640
to notice that this is not supposed to be here

00:09:45.440 --> 00:09:51.200
i know what we're doing right now doesn't look like much but this is very

00:09:49.120 --> 00:09:55.040
moment of truth for this project guys because there's a lot of

00:09:52.880 --> 00:09:57.360
redoing of fab that will need to be done if this does not

00:09:56.560 --> 00:10:03.200
fit so the motherboard tray is right up

00:10:00.480 --> 00:10:07.440
against our back adapter plate here and

00:10:04.800 --> 00:10:10.560
it looks like the screw holes are in fact going to line up but the only way

00:10:09.200 --> 00:10:14.959
we're going to know for sure is to put these in we're going to be using the

00:10:12.320 --> 00:10:17.600
shortest ones that we can possibly find because unlike the back of our

00:10:16.240 --> 00:10:24.079
motherboard tray where we're planning to do some cable routing we do not want to waste any space

00:10:22.480 --> 00:10:28.720
between the motherboard tray and the motherboard that we don't have to

00:10:26.640 --> 00:10:33.519
you know the crazy thing is is it's not even that unreasonable

00:10:30.320 --> 00:10:34.720
looking compared to the original one

00:10:33.519 --> 00:10:39.519
we've got to be careful with this board i don't think Gigabyte's sending us another one now that they know what

00:10:37.440 --> 00:10:44.320
we're doing with it maybe i called it a success too early

00:10:41.920 --> 00:10:47.120
these standoffs are pretty tight okay i got that one

00:10:45.519 --> 00:10:50.399
and yes we're gonna round this off don't worry you guys

00:10:49.040 --> 00:10:55.440
so as we've done before we just harvested uh pci slot holders from an

00:10:53.920 --> 00:11:00.560
existing case now this isn't actually it doesn't have the slot for it to come through yet but

00:10:58.560 --> 00:11:03.600
it's gonna go in kind of like that and then we're going to have our our

00:11:02.399 --> 00:11:08.000
dual fan radiator here in the back but let's go

00:11:05.519 --> 00:11:13.040
ahead and throw the cards in without that for now

00:11:10.480 --> 00:11:15.839
oh yeah wow it goes oh not bad

00:11:14.640 --> 00:11:20.160
okay so obviously our graphics card's sagging

00:11:18.160 --> 00:11:23.440
a little bit right now but this radiator

00:11:21.839 --> 00:11:25.839
is gonna go right here

00:11:26.000 --> 00:11:32.880
oh it's looking a lot more real ladies and

00:11:31.440 --> 00:11:36.800
gentlemen there it is

00:11:34.560 --> 00:11:39.680
we're going black fans right yeah yeah yeah okay

00:11:38.399 --> 00:11:45.200
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

00:11:42.399 --> 00:11:49.120
up but right now this CPU heatsink is in the way it's going to be a water block

00:11:46.640 --> 00:11:52.079
later and go ahead and put our triple radiator back in

00:11:53.200 --> 00:11:59.360
that fits just right doesn't it i'm willing to bet a lot of you didn't have

00:11:57.760 --> 00:12:03.120
