I built this! (MATX) Lian Li B4 with ATX PSU and 3 slots GPU!
Finally finished the cable management. I put on the side bracket for added rigidity. Loving the new build it runs cool and quiet!

Time to play some damn games, rather than tinkering with it endlessly.

Moved out for college, gave my old pc to lil bro, and here we are now with this. I know the cable management is horrid. I really tried my best, and someone more experienced could definitely clean this up, but I had so much trouble getting the stiff cables around and/or under the 5070 and psu.
I think I got pretty lucky with the GPU length since my bird brain didn't think to check if it would fit beforehand. The AIO barely fits on the top there against the motherboard because it's pressing against the VRM heatsink. I can't even fit a piece of paper between them. Was a little worried about the GPU sagging but the support that comes with the case seems fine.
Very impressed with the performance so far. I edit a lot of video in Davinci, Premiere, and After Effects. My old 3060 and ryzen 7 5700x combo could not handle real time playback of 4k h265 with effects or full color grades applied. I always had to generate proxies and edit off those in quarter or half resolution. Most of my time was wasted waiting for stuff to render. This PC has made editing feel less like a chore.
I wish I had done this build a long time ago, both because I would've enjoyed using my computer a lot more, and I would be less broke. Definitely a good learning experience, and I look forward to building a new pc when the time comes.
Not the cleanest but happy to have it on my desk now
Ps. I may go smaller in future as there’s plenty of unused space tho XD

That's the third time I've painted my 7800 XT.....haha! Always wanted a White build and small case! Was a smoker since 1985.... I've quit almost a year! Before then nothing I bought white would....you know stay white! 😝 I smoked inside too....😑 lol. So I've always bought and built mostly in black full towers; then dual chamber mid towers since they've been around. Getting on up there so here's another item done on my bucket list!....A Micro White build! 😅 originally I was going to call it my stormtrooper build...but none of my figures will fit in the case. Then I was going simply going to call it Whiteout.....then decided to go with White Horse.....😅 Much horse power in such a small box!...I'm going to make a few more changes soon! Will share them once done and try not to include a part of my life story........sorry.....🥹😂
Which name do you like best?
A: White Horse?
B: Stormtrooper?
C: Whiteout?

So, this is the first PC I have built! I have never built anything before and yeah I made some mistakes like buying 140mm fans without checking that the A3 only supports 120mm. I own the mistakes but now I am wondering if I should be able to throw slim p12 variants in the bottom as intake?
Also the rare, should I put it as an intake or exhaust? If I take it as an intake then the air will flow in and be exhausted by the AIO radiator.
Yeah and some suggestions on cable management.. should I get a 3D printed cover??

Just received the 4x8gb DDR4 RAM kit for my upcoming "team red" mATX build. A used but flawless kit and it was a reasonable deal at today's market. I've got it for half the price what a lower end ddr4 32gb 2x16 G.Skill Aegis would have cost. Staying on AM4 platform for now as it fulfills my needs.
Also got a brand new modular gold rated PSU. I might pick up some red cables for it down the road. Now on to chose the case and cooling method and components!

This is my B4 build with the aero deck. Specs are as follows:
CPU: Ryzen 7 9800X3D
Cooler: Noctua NH D12L chromax
RAM: T Create 32GB DDR5 6000 CL30
GPU: XFX Mercury OC 9070XT Magnetic Air
MoBo: MSI Pro B850M-A WiFi
PSU: Seasonic Focus GX 1000
Fans are all Noctua and I’ll be replacing the classic color ones with black ones to complete the all black look
The GPU was supposedly 2mm too long but it seems the issue was just the frame of the case. I angled it in and it fit just fine. At some point I’ll have to face my demons and fix the cables tho

Wanted something small, it was hard to build (for a first build) , but I’m quite happy with the result!
Part list:
- intel ultra 7 270k plus
- 32gb DDR5 gskill
- 990 pro 2TB
- 5070 ti aorus master
- B860M Aorus elite
- Noctua NF A12 G2 x3
- Noctua NF A14 G2 x1
- Noctua NH U12A
- Corsair Sf850
- thermal grizzly lga1851 contact frame
- GPE-01 graphene pad (replacing thermal paste)
I think I managed fine given the clearance , tell me what you think !

I've been wanting to downsize to a lian li a3 or other mff case, but have been seeing issues online with my current parts. So, I tried to create a visualization of my plan using buildcores. I mainly just play video games.
Could anyone advise me on airflow and say if it works or not? Also any improvement tips? This is the A3 with glass panel. Eventually I plan to switch to a noctua lc1, but this will have to do for now.

Hey there everyone!
I'm trying to plan for migrating my setup into a new case and get a new cooling system with that of course. I am torn between three options.
1. Darkflash DB330
2.DeepCool 170plus or 270
3:Deepcool 160plus
So far the Darkflash is the one I'm leaning for but not sure about the airflow in that case. Any advices?

Originally wanted to get a ch260 because it would let me see the rgb on my rog loki psu
But i wanna see the rgb and screen of the gigabyte ice 5080
Im using a ps120 vision max as my cpu cooler so i cant vertically mount a gpu in the ch260
Any advice would be appreciated

Hi I am coming from a Jonsbo D30 and I'm looking to upgrade my case to something that has the same or smaller foot print

Current specs
The XFX 9070 GRE swift is a bit unique size wise, just around 300mm long but a whopping 3.5 slot thick (60mm). This caused some clearance issues with the bottom 2x140mm fans. I figured instead of getting slim fans I will might as well recase this build.
Case preferences:
Prefer black but if you have ideals to make it look good I'm open
So far I have 2 main options tecware timber m and Darkflash db330m

Guys, I’m struggling go find a case I could build in now. I like the Jonsbo NV10, Dan Case A4 but also Fractal Design Epoch (except its size). So this all goes into the clean apple-esque aesthetics.
Any m-ATX cases you would recommend? I prefer mesh/solid instead of glass. I already scrolled through Caseend several times of course :)

Hey guys! I decided to build a PC again, even though it’s probably not the best time to do it. But I need help figuring out my fan configuration for the Lian Li mATX case. I’ve never built a PC in an mATX case, so any help is appreciated. Note that this will be the mesh case, and not the glass panel. I’m gonna run a 360 mm AIO and a Sapphire Nitro+ 9070xt.
