To facilitate identical cooling on differently-sized motherboards, we're downsizing from Noctua’s huge NH-D15 to its NH-U12S. Though the smaller dimensions could solve fitment issues with some hardware combinations, cooling our overclocked Core i7-5930K is more challenging for its single-tower sink and one fan.

We’ve also transitioned from a noisy blower-style graphics cooler to an axial fan model from Gigabyte. The GV-N970G1 Gaming-4GD keeps its GPU exceptionally cool at reduced noise, while dumping its heat directly into the case.

Power comes from the 80 PLUS Platinum-rated Dark Power Pro 10 850W by be quiet!

Benchmark Suite

Designed by committee, our new test platform runs hot and quiet, negating the dramatic performance differences its predecessor was designed to produce.

    Hmm I just got rid of my 300 about a month ago. Is this really the 300's replacement? The 300 lacked any 2.5" bays but had great cooling with only the 2 included three speed fans. It seems they made the same mistake twice by sitting the motherboard too close to the top so it is practically impossible to mount a rad on the inside there.

    Considering it is a $70 case, surely there must be much better options than this for budget builders.

    Argh, what's wrong with the site?? All the alignment is out. I was reading through the price list and the case came up at $46.99 now it says $70.

    It is 47 because it is on sale. It is a $70 case.

    I'm rather sad Antec still doesn't seem to want to make fan filters easy to access. That's why I replaced my 902, and why I've been steering people away from their cases for a while.

    To clean the filters on the 902, it required removing 20(!) screws, and this case requires the removal of the front panel, and thus, both the side panels also. At the least, it looks like the top and rear filters are a bit easier to access, which is a step forward.

    Probably not a case I'll be recommending for others to use, even if it is inexpensive.

    The 300-2 had one 2.5" spot at the bottom and another behind the motherboard tray.

    I own both a 300 and 300-2. My biggest pet peeve about them is having to unplug everything I may have plugged into front jacks and open the side panel to un-clip the front panel so I can remove it every time I want to clean the filters. Another problem with the 300s is that the filter sits so close to the front mesh that dust accumulates directly behind the front mesh' holes - there is not enough space for airflow to spread out evenly across the filter. I would probably need to clean the filter half as often if there was even only 1mm of extra clearance here.

    Yet another filter-related pet peeve is the PSU filter: half the dust gets scraped off the filter and sucked right back in when the filter is removed for cleaning. IMO, the 300-2 would have been better off without it, letting the PSU draw from case air like it did in the original 300.

    I think that Antec has been left behind in terms of case design. I do remember when I wanted a 900 but most of their cases are just now coming with features that others have had.

    I find it strange that this is lacking side fan mounts. Even the Corsair 200R has those and that is a $60 dollar case right now.

    The 300-2 had side fan mounts on both panels. On my case though, both of them are taped shut to limit dust ingress. In an ocean of cases with goady side panels. There is no point in having windows or side vents when the case is wedged between a desk and a wall. The top fan is unplugged and the vent taped shut to prevent screws and whatever else I might have on my desk dropping into my PC through the top fan.

    Sometimes, less is more. I would pay $10 more than I paid for my 300-2 for an otherwise identical case that had no side vents, no dedicated PSU filter/intake and no top vent for me to worry about but had direct access to intake filters.

    Why would someone bother to review such a mediocre product?

    I'll assume, since it is not mentioned in the article, that the two top fans are configured for exhaust. Three exhaust and no intake fans seems completely inappropriate for hot hardware. Since the option is provided "out of the box", I'd like to see the top fans moved to the front as intakes and the plug/panel installed on top. This should show very different numbers in testing. I'm rather surprised it wasn't attempted initially by the builder/reviewer as it seems rather obvious.

    I'm not sure how many users would be trying to squeeze an extended MB into an inexpensive case. I don't see it as a con at all. Many enthusiasts look for more compact cases for ATX/m-ATX builds. If the P70 will often be on sale for <$50 and moving the two top fans to the front as intakes shows better all around performance as I expect, methinks the P70 could be a killer option for moderately priced gaming rigs/workstations.

    I'll wait for a more thorough review of the product before making any final judgements...
