We've been wanting to do a mini-ITX build for quite some time. Our original plan was to keep the budget on the lower end, but after looking closer at the case I couldn't resist bumping up to a more powerful system.

Corsair kindly sent us the 250D to build with, and for a mini-ITX form factor it was excellent to work with. When all the panels are off, the interior is very accessible. It was only once we got the radiator installed that things became cramped. A quick note on the radiator - we wanted to use the H105 cooler, but it is too deep. Only the H100i would fit.

We already had the i5-4670K and 780 Ti on hand (and hadn't done a build with them yet), so we decided it was time those made an appearance. If this were going to be my daily driver, I'd replace the 1TB drive with something larger. However, we have several of the 1TB drives on hand, so that's why that was included.

Very nicely done! I love mini-itx builds, and this one is no exception. I think that the 250D is one of the cooler cases out there. This is an amazing computer, perfect for anyone with that budget.

LostNinJa -1 points 48 months ago

Well this dosent look a budget because of the "water cooled" i5 and 780Ti

Mirrorworld 3 Builds -2 points 54 months ago

Budget? Theres a 780TI and a watercooled I5 in there, Philip just threw budget out the window!

iiLeGiT101 1 Build 15 points 54 months ago

"perfect for anyone with that budget"

"with that budget"

"that budget"

I hope this clears up everything lol.

Mirrorworld 3 Builds 3 points 54 months ago

Oh sorry, didnt see that.

YodelingTerror 2 points 54 months ago

Well, considering that his "out the window" build was OVER 9000 dollars, I think this is pretty cheap. :D

CemCakan 1 Build 1 point 44 months ago

Don't worry, I see what you did there ;D

xx116xx 3 Builds 1 point 54 months ago

Some people have a $1500-1600 budget...

There is a difference between budget and budgeted, mate.

Love it!

Electrospeed 2 points 54 months ago

The best thing about these builds is by far the incredible picture quality.

skemble 24 Builds 2 points 54 months ago

Excellent work Philip!

LostNinJa 2 points 48 months ago

you should have gotten a 2TB hard drive from the beginning, Its only $10-$20 more depending on which manufacturer.

guldendraak 1 point 54 months ago

How was it building in that case? I`m considering an ITX build myself. So far the only thing I can see becoming an issue would be space and cable management. What was your experience?

philip staff submitter 10 Builds 2 points 54 months ago

I've built in three other ITX cases to date - a Lian Li PC-Q08B, a Silverstone SG05B, and a random small ITX desktop case. This is the best ITX experience for me so far. With the panels removed the accessibility is really good. Overall I really like the case. My only wish is if it had an extra 10mm, maybe 20mm extra depth for the 240mm radiator mount. The H100i does fit, though barely.

AustinTheTimelord 1 point 54 months ago

Ever consider doing one with the BitFenix Prodigy? I can't express how much I love that case and I've never used it. It's just so aesthetically pleasing to me. When ever I see a build using the Prodigy here, it's usually upvoted like crazy (with a few exceptions of course).

philip staff submitter 10 Builds 1 point 54 months ago

I have a prodigy case on hand, but for my personal taste it is just too large. It's basically a MicroATX sized. I don't know if the one I got was a bad run, but it had issues right out of the box - cracked plastic on the screwholes that hold the top and bottom plastic loop thingies, the plastic loops would bend and not lay perfectly flat when the case was on a hard surface, etc. There are issues if your PSU is deep too. I really wanted to like it, but it just wasn't for me. That's not to say that others won't like it though.

Crazyoc 1 point 54 months ago

You realise they are meant to flex right? Its why itd called fyberFLEX.

iiLeGiT101 1 Build 1 point 54 months ago

What about the BitFenx Prodigy M? Have you ever worked with that case?

Adamantame 1 Build 1 point 54 months ago

Nice build Phillip! How's the airflow in that case? Also, did you, or are you going to OC the CPU or GPU?

philip staff submitter 10 Builds 1 point 54 months ago

Airflow looks to be really good, though we haven't run it through the paces yet. Definitely want to OC both the CPU and GPU.

Did you make a video for this build?

philip staff submitter 10 Builds 1 point 54 months ago

We did! It just now finished rendering the 1080p version. Here's the link: https://www.youtube.com/watch?v=DA125dPU-uk

Graestone45 1 Build 1 point 54 months ago

Awesome :D

JasonUK 12 Builds 1 point 54 months ago

Nice job with the build. Do the H100i tubes fit underneath the ODD bay?

philip staff submitter 10 Builds 1 point 54 months ago

The way they're routed right now, I think they'd end up behind the ODD. you might be able to finagle them underneath though. The radiator only mounts that one way though - if you try and flip it around, the hoses coming out of the radiator interfere at the front of the case (with the fan I think? can't remember now.)

Is the CS just a CX rebrand? or are there any improvements?

Electrospeed 1 point 54 months ago

What no. Not even close. Different OEM, to start. 80+ Gold, Semi-Modular, all around better PSU.

Corsair has like 8 different lines of PSUs.

Zynchronize 1 Build 1 point 54 months ago

Just I havent seen any other than HX, RM, AX, AXi, CXM or CX before.

Electrospeed 4 points 54 months ago

CSM is brand new from Corsair, launched not too long ago. They're pretty obscure, for some reason I cannot fathom. They're pretty high quality PSUs for the price.

Corsair PSUs from low to high quality:


The M at the end of some of them signifies modularity.

James0n. 1 point 54 months ago

Really nice build!

crisptofu 1 point 54 months ago

but.... no overclock? you haz z87 and an h100i, don't put it to shame

philip staff submitter 10 Builds 2 points 54 months ago

Who says I'm not going to overclock? I just finished building it - the benchmarking and overclocking is coming.

JPCRacing24 2 Builds 2 points 54 months ago

Love your build! I would love to see a video or thread explaining how to overclock. I just built my 250D with the H100i, but I have no clue exactly how to go about overclocking.

Microshrimp 1 Build 1 point 54 months ago

Beautiful build! It's hard to believe that everything in this build was off-the-shelf and not custom engineered or something. I love being creative and coming up with my own build ideas (and I love mini-ITX), but if I had $1600 and was going to build a computer, I would seriously consider doing an exact copy of this now that I've seen it.

ogFrag 1 Build 1 point 53 months ago

OK so first - love this build.

And this site...

I saw this

http://www.corsair.com/en-us/blog/2014/march/250depilogue Holy cows!

And I was inspired to try my hand at my first build. I have avionics and Industrial Design degree so feel confident I can put something together... but don't have much experience with pairing components, best value, etc..

And since this is my first build I thought I would start off with just liquid cooled CPU.

After a few weeks of research and peeping other builds here I put together this list:


This is gaming rig (I have Quadro for work)almost exclusively and my goal was to go one step above adequate. I hope to do mild OC on CPU and GPU.

Any advice, questions, comments or concerns would be greatly appreciated by all! My only initial worry is that the H60 will not be adequate coz I see many going with H80 or H100i??

Alsooo I am a little above my budget so is there somewhere I can trim the fat?


Aedesius 1 point 53 months ago

You said this was just gaming, so I'm definitely gonna recommend you downsize your GPU to a 2gb 770. Even at increased resolutions the 4gb model doesn't show significantly increased performance; it's really only beneficial to SLI setups where multiple cards share vram.

Edit: also, the H60 will be adequate, but you won't be able to overclock quite as much as you could with an H100i.

ogFrag 1 Build 1 point 53 months ago

Thanks for reply.

This is current list as ordered. I did decide to drop the extra GPU RAM but in a last minute, future proof induced, panic upped to 780 3GB...


Having a bit of snafu... I was planning to run the case stock fan in front and the other stock fan + H60 on the side (positive pressure case)... but didn't occur to me that mobo only has two fan headers. Is there another way to run all three? Otherwise I will move up to H100i

Aedesius 1 point 53 months ago

Well at least with a 780 you'll definitely see a performance boost! I was just worried you'd spend an extra $70 for no real improvements. Anyway, as far as your fan issue... You could either get a fan controller (not all that expensive) or get adapters to hook them into unused ports on your power supply. I'd recommend the former as you get more control over them.

Also, I'm 95% sure the h100i uses 2 fan headers, so moving up won't really fix that problem.

xSWATxBadkid 1 Build 1 point 53 months ago

Nice build, do you think that you could put 200mm fan in the front or does the H100i block it?

KuruptNightmare 1 Build 1 point 53 months ago

That's an awesome build. Though for something smaller I don't have the budget for that. How was the cable management in this?

jmit6 1 point 53 months ago

Have you run into any problems with your MOBO?

Great build. My inspiration for a newly ordered components :)

Nice build

Lazerpope 1 point 52 months ago

And here sits the proclaimed 780ti in its natural habitat.

el3xtrosky 1 point 52 months ago

Hi there Philip, I was curious about the PSU and that GTX 780 Ti. I just checked EVGA's website for that model of GTX 780 Ti, and it recommends that a minimum of 600 watt PSU is needed to run that beast. I'm quite confused right now. So, with your setup, does it run great in Ultra settings gaming?

Blakeny 1 point 51 months ago

Wait, if I want to build this, it says the motherboard and CPU is flagged as incompatible. Is it truly incompatible?

philip staff submitter 10 Builds 1 point 51 months ago

I just double checked the part list and it's showing it is fine. Are you sure you have the right cpu and motherboard? What's your part list permalink?

Blakeny 1 point 51 months ago

I was using the wrong CPU. Is it possible for adding a wireless network adapter built in? Or will I have to use a USB connected device?

stevengibsonXD 1 point 48 months ago

could i use a amd graphics card in this build

jnanof 32 Builds 1 point 43 months ago

Is it just me or do these 250D build look nicer with the case panels OFF. Nice build.

okfolife123 1 point 40 months ago

sorry but not buying a 780ti for $700 lmao Ill just grab myself a 980

philip staff submitter 10 Builds 1 point 40 months ago

Of course. At the time of the build, the 980 had not been released yet.

okfolife123 1 point 40 months ago

Yeah I figured, but still says $700 usually the price goes down

Alagamasha -7 points 53 months ago

Well...the build for a gamer that need a super PC with a little case, but you can't put a 550w psu in a build that has a i5-4670k and a GTX 780Ti. Maybe a 850w will work better

philip staff submitter 10 Builds 4 points 53 months ago

Beg your pardon? Why not?

Alagamasha -7 points 53 months ago

A 550W, in my opinion, can't give "sufficient life" for the CPU and the GPU, but if the build has a 550W I can't change your ideas

philip staff submitter 10 Builds 5 points 53 months ago

550w is fine for the build. The estimated maximum draw for it is 413W. An 850W supply would be a waste of money, considering that the case and motherboard do not allow for upgrading to multiple GPUs.

Alagamasha -9 points 53 months ago

Not in my opinion
