[@user-gp5wu6ok3z]

I must have watched this video 60 times over. Thank you for helping me build my tower 300!

[@Tech-ot4iy]

Congrats!

[@user-oj7ew6tc4z]

Its nice! what color did you choose?

[@loganwhite6173]

my tower just arrived so I am here for the 5th time watching to make sure I don't butcher this lol.. very helpful videos

[@FluxDigital]

Was hoping you’d build in this case, nice.

[@moonstomper68]

Lovely clean build, it looks so good in that case with the component choice and the orientation of the GPU fits it perfectly.

[@Xilent1]

Really appreciate this video. Funny they didn't make the PSU covers for there own PSU to line up correctly, but its fine. I REALLY appreciate that you showed how the cables connect before its in the Case while its in the case video edit. Great job Sir. In any case, you gave me confidence I can do this. This will be my 2nd build.

[@bioniclelegend7]

Thanks for building in this case. I have bought it and was wondering if there was a build guide reference and glad I found this.

[@jasunlg]

I liked it that much I built one. Great video, I've watched it so many times.

[@lihuan9634]

thank u so much for all these builds videos..

[@ChristopherFlannigan]

No problem 👍

[@thingsyoucando6493]

I can listen to you say case all day 😂. I am thinking about buying this. Great video.

[@yokii777]

And not a single KZbinr shows how peripheral devices are connected, and this is not easy.

[@abreu7756]

the Sonic motherboard is the coolest thing i've seen since the Asus ROG Evangelion pc

[@qzrtech]

i love everything in white

[@ChristopherFlannigan]

The parts work so well together. The white and blue of motherboard and GPU work so well

[@diogofabricio7744]

Racist

[@toonnut1]

Looks good 👍

[@ChristopherFlannigan]

Thanks 👍

[@user-ci9ex4ij8z]

Круто выглядит! Продам всё своё старое барахло и соберу подобный, корпус просто огонь внешне)

[@clapped_by_r1val914]

Clean build! You should try the msi mag Pano 100r PZ

[@maximgaming1066]

Thanks

[@raystar0191]

I love this case, whole build looks awesome 🤍

[@CMan-602]

Found you while looking for builds in this case. I am waiting on the racing green or matcha green. I will be using in the horizontal position and have two questions: - what is the height when horizontal? - seems exhausting the fans on the aio would be better in horizontal position? Cheers. Great channel.

[@ivanwill]

Lovely looking case. Wondering if the extra option of the LCD screen (on the case, not the AIO) if the case is on the side, does the image on the LCD rotate accordingly?

[@dbnpoldermans4120]

I think you have the power supply shroud backwards

[@seryozha_evil]

8:42 - once you see it, you'll want to throw an angry bird at it

[@sirverbalot]

I'm quite interested in this case, but I admit I have one concern: I've got a bunch of Phanteks T30-120 fans I'd likely utilize for the build, and I'm unsure if the 30mm thickness of the fans would cause any concerns. Thanks for making these sorts of videos - your presentation style is a nice change from the bombastic stuff that seems to dominate KZbin. Cheers.

[@svensmokavich]

dont you have the airflow reversed? the TT logo should be facing forward on cooler if im not mistaken.

[@stephensullivan527]

I am very curious if a second fan/radiator bracket could be mounted on the GPU side of the case to attach additional fans as intake for the graphics card? Do the screw holes or mounting tabs line up?

que bellezaaaa

[@OntarioGuy430]

Won't the passthrough air on the back of the GPU and the air being pulled into the case by the AIO cause issues?

[@rmb658]

Can the liquid cooled version be ditched in favor of an air cooled version? Like maybe the Noctua U12A? Would that be adequate cooling for this CPU? I'm planning a build using the 14900 along with the Noctua cooler in a different case, but I love this case.

[@Memelord4dayz]

Nah, you need a liquid cooler for the 14900. Do not buy a u12a for that cpu.

[@rmb658]

@@Memelord4dayz Thanks for the response, but already done. The U12A is actually a great solution. Idle temps around 31 deg C, and less than 40 deg C under normal load which is way less than my CoolerMaster liquid cooled 7th gen i7, and WAY quieter. The only game I've played is Hogwarts Legacy with a 4070 TI with everything set to ultra. Temps stay around 70. As it turns out it's not so much the CPU as it is the motherboard manufacturers removal of Intel power limits. I can bump the power limits up a bit in BIOS and the only issue is with the GPU, not the CPU. What I would say is that rather than the Noctua cooler not being enough for the CPU, the 4070 is not enough for the CPU. Plus I don't have a bunch of liquid running around my computer. I'm quite happy with it.

[@Memelord4dayz]

@@rmb658 That's a pleasant surprise. Im glad you made it work, man!

[@keeosh]

really, why selling the chassi stand kit separately? gosh no one is selling it in my country.

[@MG0301]

this case looks sick but it's weird that you can't use the I/O Ports from the Motherboard

[@M1dn1ghtN1nj4]

Exactly. Every single build I've seen has ZERO I/O connections. Because it's impossible to get to them without disassembling the case. Kinda stupid design.

[@Max1996YT]

I do wonder why not one video about this case shows how to connect and route a monitor cable from the GPU.

[@jessevelazquez7088]

There is a pass through from the top. It's a bit annoying but any cables you want on the mb or gpu needs to be passed through the top. You will need to take the top, and top fan bracket off. Plug what ever you want in, route the wires, and close everything up. One of the reviewers said you will most likely need some extenders depending on where the tower is. If you have it horizontal, I don't see cable length as much of an issue. But, I have no built in this yet so I can't give foest hand experience.

[@Gabriel-Spirito83210]

Slt tu vas le tester le nouveau boitier asus TUF Gaming GT302 ARGB sur ta chaine ?? Un français qui adore ton contenue. Continue tu est super ^^^^^^

[@jeantechnoir7702]

It looks horrible...I want it!!

[@marleensrain]

lol i have the same motherboard

[@nyxetera]

Wait... so all the exterior cable slots (graphics card, motherboard) are hidden within the case? Seems odd.

[@robertlucke4964]

It looks terrible 😂 why do I want that case so badly now any donations for the poor lol great build love your build guides and your step by step case tear down best channel to learn how to build I tell anyone that wants to learn to build to watch your channel thank you for the content

[@StepDeady]

this guy is hacking

[@M1dn1ghtN1nj4]

😂 So you have no USB, Ethernet, audio, video card connections, wireless antenna connections, nothing......you plugged in power and turned it on, but it's not a functional PC. You have NOTHING plugged into the motherboard. Lo😂
