Benchmark Comparisons

To get as meaningful a comparison as possible between the different cases, we installed the same set of hardware into each one; our new standard ATX test bed. While our X1 and P150 did both include power supplies, we still wanted to test just the case to eliminate any other variables.

ATX Test Bed
DFI LanParty UT 915P-T12
Pentium 4 530 Prescott 3.0ghz
OCZ 512MB DDR2 x 2
Thermaltake Golden Orb II
Maxtor 80gb IDE Hard Drive
Chaintech GeForce 6600GT
MSI DVD-CD/R/RW Combo drive
MadDog MD-600SCPS PSU

Continuing with the new ATX test bed we used for the HTPC comparison, we now have many points of measurement in the computer and can get a really good idea of how well the cases are performing in the temperature arena.

Right away, the E68 really shines as a cooling champion. The large 120mm fan that is focused on forcing the coolest air right onto the hottest components of the computer is definitely a good design choice - that is, of course, assuming that one's setup would permit good airflow to the side of the case.

As always, however, temperatures alone don't tell the whole story. Since Antec makes it very clear that the P150 is all about silence, we tested the case with the tri-speed fan set to the lowest level. The noise levels from each case are summarized in the following table:

Don't let the marketing fool you - the Antec P150, while certainly about as silent as cases can possibly get, was for all practical purposes tied by the much less expensive X1. The performance of the Raidmax case in this regard really came at a surprise to us, considering the fact that the X1 was the only case that had more than one fan, but both included fans in the X1 were silent. Technically speaking, the P150 really did tie the X1, but to our ears, we still actually noticed the fan on the P150 every-so-slightly more than the fans on the X1. This is largely due to a phenomenon that we've noticed over time here in testing. Humans can perceive the sound of the actual moving air whereas the dBa reader doesn't seem to register any actual additional noise unless it's in the path of the moving air itself. Noises that have a real pitch to them are far more annoying, and tend to be much more noticeable to both humans and testing equipment alike. In that sense, the P150 is really just as quiet, as its fan wasn't making any annoying pitched sounds what-so-ever.

The E68's cooling performance is still amazing, but now, the reasons are slightly more obvious - the 120mm fan included with the case makes significantly more noise than the other two cases' solutions. That having been said, the E68 still was definitely within tolerable limits for us, and would certainly suit the majority of users fine, especially if they are used to keeping their computers under their desk and don't mind the aforementioned sound of simply "moving air".

Even focusing too much on the obvious winners from each category really isn't the right thing to do here either though; it's once when you take both charts into consideration that the P150 starts to finally strut its stuff. Compared directly to the just-as-quiet X1, the P150 keeps critical components - especially the GPU and chipset - slightly cooler. With only a single fan against the X1's two, this can only be explained by sheer good case design and a very efficient fan. However, hard drive temperatures aren't the best on the P150, so it'd be wisest to pair it with hard drives that are either known for running cool or for being able to withstand heat without any issues.

Finally, a couple of words about the included power supplies on the X1 and P150: our Antec test unit must have been defective, as it was causing boot problems in not only our test bed, but in another computer as well. When it was running, it was virtually silent - even quieter than our MadDog unit.

Update: It sounds like there IS a real issue going on with the Neo HE power supply included with the P150.. the silent PC forums make mention of it but the easiest place to see that there must be problems with it is in the newegg user reviews for the case.

The Raidmax power supply was also practically silent, and worked fine in the test bed under heavy loads for several hours, and in another gaming computer for a couple of weeks without any problems.

    Lol.. I've gotten this several times now. It's a solid, quiet, dependable, modular unit that's made by NEC. It's a great unit that we've chosen OVER similarly priced and even much more expensive units from antec, ocz, and thermaltake.

    I'm sure the first time I read the article it warned that people have been having problems with the P150 powersupplies.

    I've also seen reports of this.

    Has it been removed from the article?

    If the article doesn't mention it, here you go:

    Antec has been aware of the problem with the NeoPower 430W PSU (with Asus motherboards) that happens to be the one included with the P150. They have fixed the problem but no idea if all the P150s that were already stocked at distributors have been sold by now and the new ones have worked into the system.

    Either way, Antec support will work with you to swap you an updated model of the PSU.

    For me thre are four standards to evaluate a case: cooling, noise, installation proagmatics, cost, and "interface" (getting stuff into and out of external ports and removobale media drives mounted in it). While I realize it's a subjective thing, IMO the last is too often ignored. THis review did a good job in one aspect, noting how far the USB ports are spaced apart. But it failed to notice what I immediately saw as a HUGE flaw in the "edotors choice" case, the X1: the USB, etc ports are BEHIND the door! SO if you have anything plugged into the port, the door MUST stay open. A door is nothing more than something that gets in the way if it can't be closed. AM I the only person in the world that has things plugged into front USB ports for more than a few seconds at a time (the amount of time the door on my current Sonata case is open, to insert and remove CDs & DVDs. The front ports, not behind the door & including firewire, is a big reason I went with the Sonata.

    What I would really like to see is a case that has USB/firewire/audio/etc ports AND one 5 1/4" drive bay not behind a door, and the rest of bays hidden behind the door. Like most people I suspect I pretty much have one CD/DVD drive I need access too a lot, and another less frequently, & of course other bays with no external access needed at all. That would be cool.

    Why was the front fan mount on the X1 ignored in the review. Looks like it can hold a 120mm there too. Personally I'd mount the front and rear fans and block off the side fan (unless I was going to duct directly to the CPU) and any other large area of ventilation holes like those at the back. Looks (from the limited view in the one picture - should have taken the front bezel off and taken a shot of the naked front so we could see what's there for ourselves) like the front fan grille is very restrictive and would need to be cut out for best cooling. No real technical-level user or reviewer would have missed that.

    For the fellow in Australia looking for Raidmax, those cases are sold here under several names like Fudin and Logisys as well as Raidmax. I suppose that anyone that wants to can import them from Korea (I believe) and sell them under their own brand name. Another little item that any reviewer with any level of perspective on the PC market would know...

    One would hope to get better than superficial, FANBOY-style reviews from AT. <rolleyes>

    Another question I have is why is there a Mad Dog PSU in there? That is one of CompUSA's in-house packagers. Raidmax usually uses L&C-type bottom-feeding junkboxes...

    re. the Mad Dog PSU - OIC, the X1 can be had either with or without PSU. The OE one is a junky old design w/ only 14 Amps on the +12, so now we know the why of the PSU swap.

    And the 0.7mm metal thickness is marginal in my book. Can't imagine how that case could not feel flimsy and have ringy acoustics.

    Actually, we couldn't use included power supplies because the P150's unit would not allow us to boot the test bed.

    For a review of the P150 based on what it was designed for (silence and usability) read this review: http://www.silentpcreview.com/article272-page1.htm...">http://www.silentpcreview.com/article272-page1.htm...

    I'm sorry, but spending $150, and then going to a lot of extra effort on top of that, all to get a computer as quiet as the X1 would've been in the first place for a third the price seems a little silly.

    I compared these cases for a reason... I really like the P150 too, but I really feel people need to know that there's much cheaper options that are just as/almost as good.

    As for usability, you do have a nice point. The P150 definitely is a nice advancement in this regard. Still, please use some common courtesy and don't use the public comment space to advertise for other websites. Thanks.
