Why you might consider the new P600S over the Define R and S Series



UPDATE: 4/30/19

Credits to @Firewrath9 for suggestions are corrections.


I was gonna do a status update but this started getting sorta long, so...


After watching Paul's review of the case which went into much more detail than other reviews I've seen so far, I drew a strikingly large amount of similarities between this and the Define R6/S2 cases from Fractal (some of my personal favorite cases) with some notable differences. The P600S is basically the Evolv X with (different (IMO better) exterior paneling. Some stats were taken from the Evolv X spec page since the P600S doesnt have an official one yet.



Case Comparison

I could have easily gone in further like how both fan controllers can do 4 PWM and 3 DC voltage control, but at this point it's pretty clear that the cases trade blow for blow upon many of the categories. Many of the included accessories were welcome including the included Vertical GPU bracket (I'm not sure if only first party cables will work with this though) and Anti Sag Bracket. We have to praise Phanteks here from learning from their past mistake of making too much of the $200+ case "DLC" (Not including SSD trays? Vert GPU Bracket?)


RGB Not included. Not Sorry.


Define S2 is 130$, and always (all skus) have USB C, R6 is specific skus.

and theres more space for from rad than P600S (100+ vs 90ish)

also all them are fake EATX, (280mm vs 330mm)

Shoulda Specified R6 was the one with different USB-C SKU's. I'll update that. 


I left it at MSRP, because prices will change (and might ultimately be a leading factor into which someone should buy at any given money) seeing as how non USB-C SKU's go as low as $105 at times


Where did you find max RAD+fan dimensions? Are these official dim's or just hand made measurements?

Phanteks has it on their site, 95mm front, 65mm top, and 280mm "EATX")


thats 170mm front space for S2/R6 (ripped it off this review https://www.overclock3d.net/reviews/cases_cooling/fractal_define_r6_review/6)

and it has 285mm EATX.

also, I think you should specify where 420 and 360 rad support is i.e.

360mm rad support T/F T/F T/F  
420mm rad support T T


The 360 and 420 support Top/Front is listed in the notes, but your method is clearer. I'll update these with the notes and the "2019 E-ATX" size notes. I dont think I've seen any E-ATX cases released in the last few years that are true 12x13" boards.
