Final Thoughts


As we jump right into hardware installation and putting a system together, we'll get to know the case right away. While the top can be removed with a few screws, we left that together and simply pulled the side off and put the system together - much like you would with any other system. It is obviously a little more crowded in this case that your standard ATX case, but for the most part, things went together quite smoothly.

The system we put together is as follows:

  • Intel Core i3-3220 @ 3.3GHz CPU
  • ASUS P8H61-I R2.0 Motherboard
  • 4GB Crucial Ballistix DDR3-1600MHz
  • Zotac GeForce GTX 660 Ti Graphics Card
  • 2TB Western Digital Black HDD
  • Noctua NH-L9i Low Profile Cooler
  • Thermaltake TR2 TX 550W PSU


The motherboard standoffs were already installed so installation of the motherboard was very simple. We simply installed the rear I/O shield and then strapped the board down with the four screws that were provided. Once we installed RAM on our board we were good to go. As you can see in the image below, there isn't a ton of room in this case, but with the power supply removed, there is room to change out a basic heatsink, install RAM and even set jumpers to reset CMOS if required. While the case is pretty tight, the lack of obstructions make it workable.

Board Installed


In order to install the hard drive, you'll have to think ahead and make sure to plug in the required SATA data and power cables before you install the drive. The bottom holes for the drive are positioned so that the cables remain mostly out of sight behind the drive. This is a great idea and you'll be able to keep the cables tucked out of sight behind the drives and the power supply to make the system look better in the advent that you remove the side panel. As you can see below, there is room for a standard 3.5-inch hard drive to fit under a two-slot graphics card, but it's pretty tight. The space between these two is about the same as when stacking multiple cards for SLI so it will work. That being said, if you have a 2.5-inch drive, it will give the card more room to breathe. Of course you don't have to use any graphics card at all as most CPUs for ITX systems - or the motherboard itself has an integrated graphics controller. Our goal here was to build a system that is very compact and is still able to play most games. This can do it.

Hardware Installed


Installation of the drives, graphics cards and more requires that you think ahead and make sure that cables are in place before you start blocking things with more hardware. Thankfully, I only had to build this system once as I thought through the process and made sure my SATA cables were in place before I plugged in the graphics card.


Once you install the power supply, the system gets a little full. In the image below, we used the Rosewill SilentNight 500W Fanless PSU, but had to swap that out for a PSU with a fan as there was no way air could leave the system. That idea I had was nice, but with a hot GPU cooking things, it didn't work out. I did try this PSU without the GPU and used integrated graphics and this case, CPU and PSU option worked amazing. That is because the Core i3-3220 is such a cool-running CPU. The graphics card caused us the issues. With that in mind, if you are building a silent HTPC, the SilentNight PSU combined with this case and a Core i3 CPU will make you very happy.

PSU Installed


As you can see above, the case isn't all that much bigger than a PSU in terms of length and height. You can also see that we've installed standard components in this case and it has space to make everything work just fine. It's impressive that a case this small can house a full-size PSU, full-sized HDD, Intel Core i3/i5/i7 CPU as well as a mid-length graphics card. The layout works well, although you won't be breaking and PC Race records with this case.

On the last page we'll take a look at the system all installed and get it up and running as we draw a few conclusions.
