Question 1

Will this case except a XL-ATX motherboard?
ASRock Extreme 11 Motherboard?

Accepted Answer

You can fit any Extended ATX Motherboard, but I don't believe that it will fit the XL-ATX Motherboards. So definitely be careful before this purchase if you are restrained by the motherboard.

I will say this though, the ASRock Extreme 11 Motherboard is not an XL-ATX board, it is only considered an Extended Motherboard so this should fit in this case with no problem at all. But as I said, no XL-ATX Motherboards will fit, but almost all Extended Motherboards will. I hope this helps & I must say, this case if AWESOME !!! Everything that I was hoping for and more, by far the cleanest looking build I have done to date.

So I hope this helps and answers your question.

Question 2

Is this case also good for air cooling? Or is it strictly for water cooling?

Accepted Answer

It's an astounding air cooling case with mounts for (16) 120s or (11) 140s ..... I also mounted a 140 in the 5.25 bays.   And the (5) included SP-140s are simply the best fans I have ever owned.  The included fan PCB makes controlling them a breeze.

Tho frankly, if I was building for air ..... and was intending to stay on air, the Primo is a bit of overkill and I'd prolly get the Enthoo Luxe.

Visit the Phanteks site (phanteks-dot-com) to see a video on the Luxe

Building on air and thinking of  a move to water in the future ? this is ideal.  A 420 and 280 rad provide more than enough cooling for two top tier cards in SLI / CF (w/ 25% OC) and a 4770k (@ 4.6-4.8GHz) with just one set of fans (could do rad fans in push pull but not needed).

To my mind, this case renders everything else between $180 $400 irrelevant.  No wonder it rec'd Case of the Year award at Comdex.

Question 3

Will this case support ASUS P9X79 WS LGA 2011 Intel X79 SATA 6Gb/s USB 3.0 SSI CEB Intel Motherboard with USB BIOS as is or with some modding?

Accepted Answer

I bought the case for the ASUS Z9PE-D16/2L SSI EEB motherboard.  Specs say it is SSI EEB compatible, but it wasn't.  Seven of the ten motherboard mounting holes matched the tray's.  For the three that didn't rather than drill new holes, I used modified plastic standoffs to give the board support.  If that's OK for you, this is a FABULOUS case keeping my system nice and cool.  Everything seems very well made.  Easy to use drive trays - I would buy another for sure.

Question 4

I wanted to ask a Question about the top of the Case, I want to install a 4 x 120 Radiator but I'm not sure if the radiator that I want to buy, will fit. Whats the Space between the Mounting Brackets from the top, to the tip of the motherboard? I want to use a thick Radiator but I'm not sure if it'll fit. This is the one I'm planning on buying : Its an EKWB XTX Rad (480)

Accepted Answer

Hi Joseph,

I can't measure the top of the motherboard , had to RMA mines since last week, but not everyboard is the same is it?

Its about 3" inch and 1 - 2 centimetter from the top mounting bracket to the first/top/highest/ motherboard back plate hole socket screw.

im using xspc AX 360 rad, i have (6) NF 120 noctuas sandwiched the rads, so the top fans are loaded on top of the case (3fans), and the other 3 fans on the other side of rad on the cpu side. its very roomy. they are all pushing set to push air into the case (just my own preference).

If you are planing on using double fans to cool the rad like me then you might not have space(very tight fit or not even have space at all). If you just doing a single fan setup with rad then your thick rad is no problem. if you using a rad thats 2x bigger than avg, you would probably have to only do fans on top of the case.

hope this helps.

Question 5

Can I fit a 240mm rad in the top of this case?

Accepted Answer

Most definitely ! I have a 360mm RAD on the top & another 240mm RAD on the bottom. So you'll for sure be able to fit your 240mm up top, as well as have a ton of other options for where you would like to put it if you choose. I think there's 5 different spots for radiators of I remember them correctly. Regardless of all the water cooling "pro's" to this case, this is by far the best case I have ever owned in my 15yrs. of building, with cable management & the power supply fitted in the back side of the case makes for a very clean look. Hope this helps if you haven't decided yet.

Question 6

Will the Zotac GTX 970 ZT fit in this case? It's a 11.79" x 4.38" card. Worried about the length. I don't plan on having water-cooling, is there room for the card to go over the rad area?

Accepted Answer

Yes you should have enough room with your card, the tower itself is the best tower on the market, has more room then a mini mansion-LoL   Serious... Your motherboard will be the deciding factor in your set-up, I use a ASUS X-79 Deluxe with two NVidia GTX 660 cards and water cooler and still have lots of room. Believe me, this tower is worth every penny and more. And thank you Newegg for the great gear and best service possible.

Question 7

Is the height really 25 inches. Some sites have it listed as 30?

Accepted Answer

The case is HUGE .... the Phanteks site is the one I'd look at.

phanteks*com/Enthoo-Primo*html

newegg doesn't allow links so replace the * with .

Dimensions:  250mm (9.8") wide x 650mm (25.6") high x 600mm (23.6") deep.

Other relevant dimensions:

Graphic card = 257mm (reservoir bracket installed)
= 277mm (reservoir bracket installed w/o cover)
= 350mm (no reservoir bracket)
= 390mm (HDD cages in front position)
= 515mm (no HDD cages)

CPU cooler = 207mm high

Cable management = 30mm behind MoBo tray

Question 8

Can I fit a 360mm or a 480mm radiator in the top of the case?

Accepted Answer

According to the manufacturer's webpage, yes. I have a 240mm radiator in mine, and there appears to be enough room for another 240mm radiator.

Question 9

The specifications state that this case supports dual power supplies but none of the videos show how two are used simultaneously.  I'd like to run two power supplies, one for a quad sli setup and the other for everything else.  How are the two supposed to be installed together?

Accepted Answer

There are two chambers for installing PSU's. They are not specifically designed in the case to run simulatneoulsy together. They are designed to giove the user an option to install their PSU either on the component side or in the back cableing side of the case in order to provide more room for a large, complext water cooling set up.

However, should you choose to run both PSU's at the same time, all you need to do is to install one in the front chamber (the chamber that is located inside the windowed side of the the compter where your components will be), and one on the opposite side, located in the rear (right cableing) side just adjacent to and on the other side of the metal divider that separates the component side from the cable side of the case. This case is large enough to accomodate both.

Just as a suggestion, you can save some money because you actually may not need two spearate PSU's powering your system, even if it is a quad SLI setup. A good 1000 to 1200 + watt PSU's should work just fine for all of your components.

Good luck. This is a beautiful, larger and extremely well designed case and I am sure you will enjoy it no matter what your set up is.

Question 10

Have the fit and finish issues been resolved? The reviews reflect quality issues in/on the plastic parts, breaking during or prior to shipping. The last thing I would want is to spend 200+ on a case only to receive it broken.

Accepted Answer

My box came damaged but the contents were all in good condition. The fit and finish is exceptional as good as any case I've had. I'm only slightly dissatisfied with the side panel glass and have yet to take it up with Phanteks. It's my understanding customer support has been very good from and owners club I belong to.
