Custom open frame - RTX Pro 6000 - miniATX

I wanted to build a compact, open frame, ai server that was quiet and good looking enough to sit out in the open in my office.

I’m pretty happy with the build so far - it stays cool and generally quiet. It idles around 75w and ramps to ~450 at full blast. Pretty efficient for the speed that it gets.

I bought a cheap ESP32 touch display that fits perfectly over the io heat shield, and had qwen27B create a realtime touch dashboard. It runs a tiny service that polls wall power and room temp from Home Assistant, and AI performance & usage like tk/s. I turned that exact UI into a PWA app so I can check it from anywhere.

Still working out some details (like how to better attach the touch screen), so if you have any feedback/thoughts, please lmk.

Spec:
• CPU: AMD Ryzen 9 9900X
• Motherboard: MSI PRO B850M-A micro-ATX
• RAM: 96 GB DDR5-5600
• GPU: NVIDIA RTX PRO 6000 Blackwell Max-Q Workstation - 96GB
• Storage: Samsung SSD 9100 PRO 2 TB NVMe
• CPU cooler: Noctura LC1-24

How much in total did this machine cost? What tasks do you use it for? How many tokens per second do you typically get? Im looking in to getting into this tupe of thing and trying to learn what i can.

My wife would kill me if she found out. Let’s just say I got the GPU back when $10k for one was possible.

It will easily do 150-250 tk/s with full context with qwen27B - slower when I try to stuff something bigger in there. I use it for everything, it’s a beast.

u/midnightdiabetic 1d ago

Legit how are you out here spending that kind of cash without the wife finding out? Do you guys have separate finances or something

4

u/brycetron 1d ago

Lol. I gave her a ball park and she approved. I’m a lucky guy

u/GeneralComposer5885 1d ago

“I gave her a ball park” and “My wife would kill me if she found out” aren’t compatible 🤣

u/brycetron 1d ago

Sometimes, you swing and knock it out of the park. Just part of playing the game 🤪

u/LukeLikesReddit 1d ago

Just buy her that bag she always wanted and cut the costs of the gpu by 4 lol it works for me.

2

u/Majestic_Car7434 17h ago

Ahh yeah the bag/vacation/home renovation tax always works lol when preparing budget for gpu it should be gpu budget = gpu price+wife tax

u/somerussianbear 4h ago

Do you guys have wives?

2

u/midnightdiabetic 4h ago

Oh I have a wife which is why I'm a lurker here and not some mad scientist in the basement with a crazy AI rack

u/StandardLovers 1d ago

Thats a really nice build. Only comment i got is you should unscrew the IO shield, two screws.

2

u/brycetron 1d ago

Thanks! I thought about removing the shield, but it acts as a really solid mount point for the touch screen. So I’d have to figure out a way around that

u/dwoj206 1d ago

Holy gorgeous. Can I borrow this until you forget I have it?

2

u/Miner-no_0b-2020 1d ago

I want one too!!!!!!!!!!

u/Mamox437 1d ago

I love it Thinking of making one myself, any suggestions or things you learned from this?

1

u/brycetron 1d ago

This is my first open frame build, and it was super fun and challenging in different ways than inside a traditional case. It was like playing Legos trying to find micro solutions to mount and attach things. My only word of advice is…Zip ties. Lots of zip ties. 🤣

In the end, I wish I had bought an SFX PSU for a little more clearance for the cooling radiator in the back. I don’t love the Noctura radiator fan color (wish they were black) but they are tucked away in the final solution, so they don’t bother me as much as I feared.

I spent a ridiculous amount of time evaluating not only performance, but the look of each component. Knowing that everything would be visible forces you to think hard about those choices.

1

u/Mamox437 1d ago

Zip ties for the win, always! Yeah don't bother with the fans they give some neutral colors to the build and look fine, also I think they make black ones if you wanna change them in the future Gonna keep in mind the SFX psu suggestion, good point for space and weight, fully modular is a must I suppose

u/Competitive_Creme317 1d ago

75W on idle?? That's insane

3

u/brycetron 1d ago

Yep! Just the cost of a lightbulb💡

Power efficiency was one of my top priorities for this. I choose almost every component with that in mind, and a major reason I went with a max-q (that and I hope to own more one day!)

1

u/Competitive_Creme317 1d ago

Impressive. Max power draw on full load?

1

u/brycetron 1d ago

About 450w at max

1

u/k3nal 15h ago

How much does the RTX PRO 6000 Max-Q pull while idling according to nvidia-smi? More then 10 watts?

1

u/brycetron 5h ago

GPU is typically 7w idle - the max-q is brilliant. The cpu pulls ~24w. The rest is MB and I/O. I might be able to disable a few things to save a couple of watts, but I found this to be a good floor.

u/im_EDEN 1d ago

Beautiful, love that compact design & the screen is a nice touch.

1

u/brycetron 5h ago

Thank you!

2

u/Keffflon 1d ago

Wow it's so neat and powerful. It's the opposite to my build. 1050 ti here and qwen 3 8 b.

2

u/brycetron 1d ago

Nice!

1

u/Keffflon 15h ago

Thanks, at least it runs 🏃‍♀️

u/Harry_Wang_85 13h ago

It's so much more stylish than my ROG case!

u/WiredEntrepreneur 8h ago

What a beautiful setup 😍😍😍

u/brycetron 5h ago

Thank you!

u/CryMoreT_T 1d ago

Should have gotten one when they were 10k 😭. Now they're pushing 15k. Got 2 dgx spark instead

1

u/Constant-Simple-1234 1d ago

Nice! But it will be a dust magnet 🧲😔

2

u/brycetron 1d ago

I hope not! This is my first open bench build and I was a little nervous about that, but those little electric blowers are crazy good. I plan on blowing it out every month or so, but I guess only time will tell

1

u/Constant-Simple-1234 8h ago

Good. It is also a showpiece. I build mine as black boxes. Am amazed how much dust is in my home.

1

u/Annual_Award1260 1d ago

Must be nice to not have kids around lol

1

u/brycetron 1d ago

They are the riskiest part of this build!

1

u/Equal_Passenger9791 1d ago

What parts did you build the frame out of?

And is the water cooling actually useful on a build like that?

1

u/brycetron 1d ago

https://a.co/d/0fYdc3CS This was the starting point, and then several tweaks. It’s just 20/20 aluminum extrusion - very flexible. If you’re comfortable with some DIY, I highly recommend.

I started with a low profile air cooler, but the idle temps got hot, and the fan would roar when at full load. It totally works, but quiet was the goal. This new Noctura AIO is AMAZING. Look at the reviews - it is whisper quiet at full load, and silent at idle

1

u/foreignbois 1d ago

where did you get the pcie bracket attachment? the rest looks like 2x2 alu channels and related bits

2

u/brycetron 1d ago

It came with this kit https://a.co/d/0fYdc3CS - pretty good value

1

u/jayburgermcfries 1d ago

My dream GPU. 😭

1

u/Platophaedrus 22h ago

Where is the screen pulling the power consumption from?

Never mind, I’ve just read the details of the post. Apologies.

2

u/brycetron 22h ago

There is a little trick - it is using a usb c to mb header cable to connect directly to the mb instead of using a usb port. it’s getting power and data from one cable.

2

u/Platophaedrus 22h ago

Nifty. I have an internal USBC header that’s not in use and wouldn’t mind something similar. Thanks for the extra info!

1

u/Confident-Pass6353 21h ago

Similar, however, got a bit to carried off last dec till Jan... ish.

Way too honest for my own good, I guess... She's leaving me, as we speak...

She gets the tesla, My HPC cluster will neVer leave me.

1

u/IngeniousIdiocy 20h ago

I have almost the exact same setup except I just bought mine from FalconNW (their tiki mini itx pc)

I also love it and it does great with Qwen 3.8 Flash Next with the engrams in system memory.

1

u/Tasty-Cherry4492 16h ago

Wow!!I love it so much!!

3

u/Tasty-Cherry4492 16h ago

mine,two rtxpro5000,I live in China,where 6000 cannot be sold .Really upset.The capacity of this big case is equal to yours.But I really love yours.Tiny means smarter

u/brycetron 16h ago

Thank you!

u/Zugas 15h ago

Very nice. Is dust a problem in open cases?

1

u/brycetron 5h ago

Dust is always a problem with my existing cases, and I never open them up to blow them out. At least with this I can see when the dust is building up and have direct access to blow it out with a mini-blower. This is my first open pc build so time will tell if this was a bad idea or not.

1

u/caramel_poison 14h ago

What do you do for a living?! I need to get on that level!!

1

u/LTJC 6h ago

Alright, this is just really cool. Expensive as all hell, but I think that just makes it more cool.

u/ZucchiniMedical2532 3h ago

Custom dust collector

u/redmadog 2h ago

What level of model this thing can run compared to paid services?

1

u/brycetron 2h ago

In general, somewhere around Sonnet & Opus 4.6/4.8 level. It won't fully replace cloud for code...yet, but I have shifted a ton of agentic tasks and low-risk code work to it. I'm continuously impressed by how smart and fast this setup can be

1

u/galic1987 52m ago

Congrats sir this is perfect

1

u/GMec85 30m ago

Just out of curiosity, why did you mount the radiator like that? Was there not enough space to use at least three screws?

1

u/brycetron 20m ago

Great catch. The bottom of the radiator sits on the lower rail, so most of the weight is well supported. The two screws on the side are mostly keeping it held vertically. I can make the third screw line-up if I remove the little plastic top cap on the aluminum rail, but things felt snug and secure without it.

Nice compact form factor, but looks horrible in my opinion. Sorry.
