This machine is meant to be a television-connected Steam Machine & HTPC. It is designed to be compact, quiet, and provide excellent value-minded performance and overclocking potential.

Windows 8 was chosen simply because it's easier to see and use on a television in a living room setting than Windows 7.

Benchmarks, temperatures, and scores are based on stock speeds (no OC).


This case (Corsair Obsidian 250D) is made specifically to accommodate the Corsair H100i water cooler, but this motherboard requires that things be installed very specifically. The case provides a variety of mounts for the radiator, but you must mount the radiator on the brackets closest to the front of the case. If you mount it on the rear-most brackets, you won't have enough room to install the motherboard as the pipes will hit the USB2 plugs.

There is also only one functional orientation for installing the water block onto the CPU (see photos - pipes should be facing the radiator)... any other orientation and the pipes will conflict with the RAM, CMOS battery, or motherboard outputs.

The case itself includes two fans - a large intake, and a smaller exhaust fan. The exhaust fan is not used in this build as the radiator fills the exhaust vents.


The Corsair Link software that controls the H100i pump, fans, and LED is not entirely compatible with the Z87 chipsets just yet (according to Corsair's forums). It requires some registry tweaks in order to get the Corsair Link software to "see" the H100i hardware... and even then it doesn't quite behave. Hopefully Corsair fixes their software soon.

Dat case... <3

Looks nice, case looks awesome though i have no clue why you got that graphics card... why not the 770 2gb? i highly doubt a steam machine will perform on tri-monitor or high resolution...

Veraxus submitter 1 Build 1 point 44 months ago

I'm intensely loyal to EVGA, and going from a 760 to an EVGA-manufactured 770 at the time would have been too much of a cost jump... and I got a great price on this card, so I figured "what the heck".

I may use EVGA's Step Up program to upgrade in the next 90 days... especially if I get lucky and the 800 series is released in that time frame.

I would've put some fan grills on the H100i fans just in case. Awesome build though. :)

Nice temps

Nice build and like the name reference! That is one cool little case.

Am I the only one who thinks the name 250D is kinda funny? Great build. But man - it looks really tight in there with the optical drive. Even with the H100i it still looks pretty tight. Definitely one of those cases where you have to use OEM spec stuff and there's basically no room to do anything whacky.

basedgodunicorns 1 Build 1 point 44 months ago

I have the H100i as well and run Windows 8.1 and Corsair Link without issues. Perhaps yours is an isolated issue?

Veraxus submitter 1 Build 1 point 44 months ago

I've dug further and popular opinion on Corsair's forums is that the Corsair Link software specifically has problems with Z87 motherboards. So until they release an update for Corsair Link, I guess I just have to deal with it.

How did you get that case? It doesn't release until the 28th?!

NM totally found where you can buy it straight from Corsair! Went ahead and ordered mine along with the rest of my parts! :) +1 for your build!

AustinTheTimelord 1 point 44 months ago

Oh look. Doctor Who reference. Yes. I approve.

How did you manage getting a seasonic for $96?

dan000 1 Build 1 point 44 months ago

It was a newegg sale, will be $76 after the $20 rebate comes in.

Veraxus submitter 1 Build 1 point 44 months ago

It was a double-whammy combination of a Newegg Flash Sale ($96) and a $20 mail-in rebate (which I didn't list since I haven't gotten that back yet).

RichardFoxfire 1 Build 1 point 44 months ago

First off +1 just for the name..lol

Second, other than the software glitch, how you enjoying the H100i. Got one for the build I'm preparing and been hearing about lots of issues, like pump noise, failing LEDs and software glitch between Link and Windows 8.

Veraxus submitter 1 Build 1 point 44 months ago

Other than the software annoyances, I'm absolutely loving the H100i. Mine is utterly silent when set to "Quiet Mode", which is where I keep it at almost all times (in fact, the CPU Temperature Under Load I reported is Quiet Mode and stock CPU clock).

When you set the cooler to Performance, it gets pretty damn loud (and painfully shrill), but the cooling performance is outrageously good... especially in this case. It's just insane how effective it is.

Also, since the software controls the LED, I have a problem where my LED keeps resetting to white every time I start the system. As soon as I change a single setting in Corsair Link (ANY setting), it fixes itself. It's just weird.

hohntomek 1 point 35 months ago

you can just get 64 gigs of ssd for your os and then like 50 bucks for a terabit of normal hard drive, also, you could have sacrificed your water cooling to get a i7 cpu and get a cheaper cpu cooler.

Veraxus submitter 1 Build 1 point 17 months ago

Given the limited internal space, attempting to use any CPU cooler in the 250D other the H100i (or similar liquid cooling) would be a huge mistake. This case was designed on the assumption of liquid cooling, and it's internal layout was designed accordingly.

Awww so cute! Needs to be next to a 900D.

Best. PC. Name. Ever.
