Very Nice Case

I bought this case for my pride and joy and I don't regret it: I can't fault anything. The design is very nice and classy, the build quality is excellent, nice and roomy inside. Worth the money.



Well cant say a thing wrong about this case.... build was easy and lots of room for routing cables and you can hide a multitude of sins behind the motherboard tray as there are a few cm clearance to the case side when fitted.

I have an I7 930 and 3 mechanical HDDs as well as an MSI 7950 twin frozer and using only the 3 provided corsair fans and a left over fan control switch I had I managed to get all 3 and both cpu fans running at practically silent speeds.... and this case is much cooler than my old thermaltake Mozart! I am not kidding when I say the only was you can tell its on is the power light.... even under full load the only thing you can hear is the GPU fans getting louder and even then its barely a nuisance. All HDD resonance and noise, the bane of my old case, are gone!

Shame about the plastic top and steel sides but the brushed alu front is very sexy... for the price an amazing case that will not disappoint!


Decent case

I looked around for some time for a case that would help silence an already quiet 2700K system and was not too heavy. The 550D met these requirements. I don't overclock and my temps are lower than they were in the Nexus Prominent 5 case that previously held my hardware. Building in it is fine with one or two niggles: I had to break off an easy-install 5.25 lock mechanism because it would not hold my fan controller firmly (and had to use screws instead); the Corsair AX850 psu screw holes did not properly align with the holes in the 550D (but can be bodged); the door needs too much effort to open. But the case has reduced what noise existed before and it's build quality is pretty good. It was nice to have plenty of room for cables. Overall, I'm happy with the case.

If you're after a quiet case for a gaming rig, then look no further. It's a joy to work on and really delivers on the silent front!

It's obvious that a lot of thought has gone into the design from an aesthetic and building perspective. The hdd cages are fantastic (although I'd recommend losing the top one to improve airflow). Also loving the idea of the extra pci bay (great for fan controllers etc).

If I was being picky, I'd like to see a bit more space at the top for thicker rads (my H100 fits perfectly) and even an extra 5mm on the other side of the mobo for cable storage (modular psu recommended). Although the door can open either way, it's quite stiff so I recommended picking a direction and removing a hinge on the opposite side (makes it much easier to open).

The stock fans are fine, but I replaced them with a combination of 120mm Apaches and 140mm Zaward Golf IIIs (quieter and shift more air).

Kit inside!
Asus Rampage IV Formula x79 ATX
Corsair H100
etc etc

Restricted to ATX size max is a bit of a problem. With a slight change it could take E-ATX. But regardless its a great size and looking case. Feels strong and quality. Waited for this case to be just the right price. Good old ocuk dropped the price on a load of corsair kit for ivybridge, i nabbed the case!
