Hey everyone,
A while ago I posted here asking for advice and hunting for the right case for this project [link]. After a lot of searching, I finally landed on the Cooler Master MasterFrame 400, and the build is officially done.

Well... as done as a PC build ever gets.
There are voices in my head....

Can I fit 2 140s in the front?
How can I get rid of that ugly gpu bracket and make use of the ASUS - Noctua?
Would it be possible to make a vertical mount build?
And much more - it never really stops.

Let me know what you think of how it turned out! If anyone else here is running a MasterFrame setup, l'd love to exchange thoughts, mod and build ideas etc.

Hi, slight update to my build from last time. Changed the 240mm Kraken Elite to a 280mm Elite RGB. Was keen to make the change happen from the start as I felt the PC was running loud with air through the radiator whilst keeping the CPU temps in check.

Initially I had a Corsair 280mm in place to test it, and whilst I’ve went with the NZXT for aesthetic reasons, I think the Corsair was actually a bit better at cooling under heavy load. I may visit this again in the future but for now I’m happy.

Added the 280mm RGB fans from the cooler to the top of case for extraction, and since they aren’t the performance fans like the F280x they run a fair bit quieter. Returned the F240x, and the 280mm fans do fit but a bit of a squeeze against the radiator in the front.

Last change I plan to make will be to try and ‘tidily’ remove the front fan brackets on front of the case to allow the RGB on the F280x to shine through properly.

Specs:

Case: NZXT H3 Flow
CPU: Ryzen 7 9850x3D
Cooler: NZXT Kraken Elite 240
Fans: NZXT F120x/F240x/F280x Performance Fans & NZXT Hub
RAM: V-Color DDR5 32GB 6000mhz CL28
GPU: PNY nVidia RTX 5080 Slim OC
Storage: 2TB Corsair MP700, 2TB Crucial P310, 2x4TB Samsung 870 SATA & 4TB WD Blue SATA
PSU: Corsair RM1000x

Debating on taking my PC from this to a black wood Liam Li A3? There's nothing wrong with my system so it's that old adage where if it ain't broke don't fix it but I don't know if I want the aesthetic of the A3

2nd PC built! I messed up thinking I could add 2 intake fans on the bottom and ended up having to pull the GPU out and removing the fans 😂. Now to reconfigure my fans, i was thinking 2 top fans for intake and 1 rear fan as an exhaust to create that positive pressure. Right now I have 1 top front intake, and rear/rear top exhaust. Also included on the last picture was my first built that i sold to build a more compact one, that mid tower was huge. Don't mind my striping job on the rams, will need to be redone.

Finally built my new pc!!

upgraded from 1050ti --> 9070xt

montech ax120 case fans

Z20 case through‑flow air‑duct setup: SFX power supply is secured to the upper fan mounting slots with cable ties. A 140 mm intake fan is installed at the front, establishing a front‑intake rear‑exhaust through‑flow airflow. Real‑world testing shows significantly lower temperatures under stress‑testing, and much quieter noise levels during gaming.

Switched to a Jonsbo Z20 does anyone have any cable management tips, I plan on getting a 9060xt and switching to a SFX power supply

Hello it's my first time posting here, I just wanted to share a build that took blood sweat and tears.

Almost everything on it but the mobo, CPU cooler and fans are from FB marketplace.

Also wanted to share that it's possible to make a non modular PSU fit in a CH160 plus with just a bit of cable management.

Finally i wanna give a shout-out to masking tape and deepcool for including zip ties, both made my life easier.

Specs:

Mobo: MSI B850 Gaming Plus WIFI 6E

CPU: AMD RYZEN 5 7600X AM5

RAM: Kingston Fury Beast 32gb 5200mhz

GPU: Gigabyte GeForce GTX 1050ti

Storage: 500gb M.2 PCle 3.0 NVMe M.2 SSD & 1TB HDD

PSU: Gigabyte P650B

*R7 5700X3D + AMD Wraith Prism [modded to look like AMD Wraith Max]
*ROG STRIX B550i GAMING
*ROG STRIX 5070 Ti OC
*32gb CORSAIR VENGEANCE LPX
*250gb WD BLUE SSD
*1tb. WD BLUE HDD
*1000w CORSAIR SF1000
*TEWARE FUSION SFF HYBRID [sama im01 variant]

I original started this around the end of 2025 and build it around feb this year. sharing short rundown. did some minor adjustments to my build. I can say it's finally complete but if you have improvements suggestions, I'd be happy to have a conversation in the comments!

CPU: l asked if I should aio liquid cool my 5700x3d and I don't think I need it for now. haven't experienced thermal throttles so far. been using this pc for 100+ days, temps are okay using the amd wraith prism cooler.

GPU: the gpu is a beast! I probably should upgrade to a native 1440p monitor with higher refresh rate to fully maximize it. don't mind the gpu sag! I couldn't find a bracket compact enough to fit the case.

RAM: dimms are only 2400mhz. too slow for today's standards but I really like the looks of Vengeange LPX so it stays. why did corsair stop making them? this is an upgrade I'd like to prioritize, hopefully there are good deals for a Vengeance LPX 3200mhz 2x16 or (2) 1x16 sticks.

STORAGE: still rocking old meta in 2026 lol. AM4, SSD and HDD combo. I am looking to upgrade to m.2 but I don't see a need for it at the moment. maybe if prices dip to reasonable levels? or that's just cope.

CASE: I rebuild the pc and I spent more time routing exposed cables making it more tidy. I tried to do better than the last attempt and I was lucky to get a tg panel for this case, nice little upgrade from just the metal mesh panel in the previous build. If you noticed, I don't have any case fans [yet] because I don't know if I need them. the panels are easily removable so I just take the panels off during sessions.

MOBO and PSU: I can't say much about these components rather than I've specifically picked them out lol.

Finally finished my Newway NC1 build / DIY steam machine ! The hardest part was just fitting the gpu in, every millimeter counts, and I had to squeeze all cables on the bottom right.

Full build specs:
● CPU: Ryzen 5 9600X
● Motherboard: MSI B850M Mortar Wifi (mATX)
● RAM: 32GB DDR5 6000 CL30 Patriot Viper
● GPU: ASRock 9070 XT Challenger
● SSD: 4TB Lexar NM790
● Cooler: Thermalright AXP90-X47
● PSU: Gigabyte GP-UD850GM (ATX)
● Case: Newway NC1
● Fans: Mostly Noctua Redux, one Noctua Industrial (bottom left) and the stock fan on the back

I went with the MSI B850M Mortar because it looks cool as hell. The full-size ATX PSU was a headache since it forced all cables to pack in the tiny bottom-right space, but with a lot of pushing and folding, it worked out. The USB3 connector was a pain too, it doesn’t bend very much and takes a lot of space where the bottom fans and additional PCIe power connector should be.
The AXP90-X47 cooler scared me a bit when it bent the motherboard (because it uses nuts instead of spring screws), but it’s probably fine.

It took some patience and sweat and I’m really happy with how it all came together in the end.

Thanks to u/GeiharVonArpen for his similar build post, I based my airflow on his.

Hello, this is my first time posting in this sub and I would like to ask for your opinions and expertise in creating the optimal fan setup for this case. My cpu is the intel i7-13700k and gpu is rtx 5070. Due to my cpu running hot compared to current gen amd cpu, I need help in having the best fan setup to cool the cpu. I 3d printed some front fan mounts to better aid in cooling it. But I am not sure with the side fans if there are the way to go since I saw GamerNexus' post that it does more harm than good. I am also using the artic liquid freezer 3 pro 240mm aio. front, side and rear fans are the artic p12 pro and the bottom fans are artic p12 slim.

RGB not synced yet on this picture.

I build it almost completely out of second hand hardware (except PSU and the case)

When I found b550m aorus elite/5700x and some coolermaster tower for 3800kc (182 USD) I knew its my time for it 😁

Rest of the specs are
DDR4 Corsair 3600mhz 32gb 2x16gb kit
750w psu gold rated
5070 MSI gaming trio OC 338mm long, price around 900 usd new here in Czech Republic now

All of it for 26200kc (1250usd), glad it fit together, and 5700x already rocking -30 PBO, great temps and its almost quiet 🙂 with time I will change air tower for something nicer

Had issues with cable so I had to redo it almost completely as pc did not post. Quite nightmare frankly 😀 but happy that its done, quite tight fit with the cables even with modular psu though.

Just built this two days ago

I have put the top fans as intake

And rear as exhaust.

Temps are around 50c when idle and 80-85c at 70w use

Hello, I just finished building my first pc few days ago !

Here's the parts :

- MSI B850M Gaming Plus Wifi

- XFX RX 9070 Swift OC Triple fan

- Ryzen 5 7600x

- Thermalright Peerless Assassin 120se

- Patriot Viper Venom 2x16go 6000mHz CL30

- Kioxia Exceria Plus G4 2to ssd

- Montech Century II 850W Gold

- Arctic P12 Pro and P12 Pro Reverse fans

- 1 Magnetic Dust filter for the rear intake

I also added the GPU Sag Bracket after taking those pictures.

Cable management wasn't easy, I did try my best at it.

It took me around 6h to achieve it (had to reopen it few times cause cable management disconnected JAUD1 and JFP1 pins few times...).

I broke my GPU retention lash during the process while trying to pull it off 😂😅

I may buy a 8.8" screen to hide those ugly cables beneath the PSU, or maybe ask a friend to 3d print me something to hide them.

EDIT: So as many did with this case using the rear exhaust fan intake with cpu cooler reversed and exhaust on top. I found this optimal since there is no clearance for fans under the 9070xt sapphire nitro.

That being said I have no issues with temps so far while gaming. But not 100% certain because I havent seen my cpu Watts going over 50 (and I've tested heavy game titles like Cyberpunk, Cities skylines 2, Black Myth Wukong

-30 negative pbo on ryzen 9800xd3

+100mhz Oc

- termal limit to 84c

-60 sapphire nitro + with 150 clock and 200mhz memory. Had to tweak GPU temps to + 10% p1 and p2 25% p3 p4

Summer time in Spain so room temp is 28 30c.

CPU temps 44-50 iddle 60 to 65 under load on gaming ( Cinebench they got 93 to 95 thats why I added an 84 termal limit)

Did notice only gets 50watts average on cities skylines 2 and not more​(I wonder if this is normal)

Gpu temps about 41 iddle, 60 - 65 underload gpu Hotspot 80-83.

So my question is...... since I wanna get the lían Li hydroshift 2 to improve CPU Temps, the noise and looks. But I really don't know if it will be worth it or counterproductive:

I have no clue how to set up the airflow then.

A: top radiator intake and rear fan exhaust

This should be the classic but I'm worried about if my gpu temps will raise since only 1 fan is exhausting air and hot air of the gpu tents to go upwards

B: radiator top as exhaust and rear intake

Would help my gpu breath more but I'm assuming that hot air will be sucked by the radiator and make the cpu hotter? ( but I also thought an air cpu cooler heatsink is also getting hot air from gpu only is getting suck by the upper fan...

C: don't even know if possible. But I thought of mounting the psu sideways to be able to place 2 fans in front.

D: even more stupid! 2 radiator fans intake and flipping the rearest top one as exhaust (together with the rear fan so it would go up diagonally)
What so you guys think? Excuse my English!

I am still waiting for the riser (damn Italian carriers) to arrive because without it I can't print the remaining panels and, obviously, I can't finish the case I was working on lately.

But fuck it, I just started another project and I am quite hyped.

I took inspiration (and maybe more than just inspiration lol) from the SFFtime N-ATX and P-ATX because I absolutely love the design of those cases, but I wanted to push the features much further:

This case will have two different versions: a short and a long one.

The short version supports ATX, mATX and Mini-ITX motherboards and uses a Flex ATX PSU. Depending on the motherboard configuration, the PSU can also be repositioned to the front/top area instead of sitting behind the GPU.

It supports GPUs up to 307 mm long, so yeah... even a 5090 should fit

The long version is where things get a little crazy.

We're talking about over 400 mm of GPU clearance, so basically you can fit pretty much any GPU currently on the market. It supports ATX, mATX and Mini-ITX motherboards, and can take Flex ATX, SFX and even full-size ATX PSUs.

It also supports up to a 280 mm radiator with low-profile fans.

And if you don't want to go with liquid cooling, both versions can fit air coolers up to around 90 mm tall.

The short version is roughly 15 L without the center foot, while the long version is around 19.5 L.

The design is still very much WIP, though. I still have to finish all the mounting points, radiators mesh side panels, connections and a ton of small details. Printing this thing is going to be a whole different kind of pain because my printer has a 250 × 250 mm build plate, so the case will have to be printed in multiple sections.

Hopefully it will actually come out as good as it looks in my head lmao.

I'm also considering trying to put this one on Kickstarter, because unlike my previous case, this project could potentially cover a much wider range of hardware and users.

Anyway... Yeah, I think I need to buy more spools of PETG.
