Fantastic for the price!

I used this case for my very first PC build, and I'm VERY happy with the result. Cable management was fantastic, and it's nice and small- it fits into the desk cubby left behind by my old, crappy Compaq micro-atx desktop despite being a full ATX case with large components.

-I/O routed well
-Cable management fantastic

-Window scratches VERY easily.
-Paint scratches fairly easily as well
-Top fan grille has no filter and doesn't look great
-Still lots of empty space if you have no front radiator
-No reset button (why???)

As a first-time builder I found the case VERY easy to use and I love how small it is compared to other ATX towers. I hope this case's popularity will make other companies catch on and realise that the ATX market also wants compact cases that don't have loads of HDD mounts or front bays. The two HDD mounts in the S340 are plenty.

The one thing I will say is that I seriously recommend using a fully modular PSU. Mine is NOT modular and getting all those unused wires to play nice and fit in was a huge pain. They all fit in the case fine, but since the PSU shroud isn't removable it can be hard to work in the nest of wire, as the HDDs are also found under the shroud.

Fantastic case for the price

What can I say?
I purchased this for my fiance to go along side my own NZXT H440 and the Source 340 was extremely easy to build in and looks great.

Cable management is surprisingly simple in this case, easily able to hold all the cables in place. There is a grill on top that takes up to a 140mm fan and has a great amount of clearance over the CPU and mainboard. The HDD shelf is very well placed, keeping it hidden at the back.
If you're looking for a budget case that's very well built, loads of fan space and looks amazing, NZXT have beaten out the competition with this case.


please buy this!!!

if you are on a budget or even if your not you need to buy this case. I was skeptical about the optical bay but when i thought hard about it i dont need one, its beautiful with a window and is built really well. Ive had soo many cases over the years and i never spend more than 100 this is by far the best case ive had for under 100 pound, its incredible and the cooling is great if u set it up right lovely ambient temps.


Compact and looks great

It took me a while to find a full ATX case without all the extra (wasted) space at the front for an optical drive or 500 HDDs. This is perfect.
Looks amazing and takes up relatively little space on my shelf. I love that the PSU and HDD are locked away from view under a bottom tray. They're still easy to access from the back, but far less wires on show. I also love the wire management system using a plate rather than grommets.
The only thing I would say is I couldn't take the plate out (not sure what they screwed it in with!) which made fitting fans on my front radiator a little tricky.
Defiantly recommended if you're looking for a small case without the need for an optical drive. If the plate came out it would make wiring even easier and get a full 5 stars.


Cracking little Case

Just bought this case, its fantastic and incredibly robust for its price, almost full steel, i did not notice at the time of ordering however that is doesn't include a optical bay for your CD ROM drive, not a big deal though. Here is a great review on the Case. Highly recommended.
