I was not impressed with the ISK100 I used for my last mini-ITX build.

With this one, I has looking for something slightly bigger and more powerful - the ISK 300-150 fit the bill.

Where the ISK100 was very inflexible and difficult to work with, the ISK 300-150 provides a bit more space, more power, and provides options to expand.

I am using a Xeon E3-1230 80W CPU and I wanted to be certain there would be sufficient cooling for it. The case ships with one TriCool 80mm fan. It provides the additional slot for a second one (which I just installed - less than $5 through Amazon/Beach Audio). There is no necessity to use a TriCool for the second fan - any 80mm chassis fan will do. What makes it a "TriCool" fan? It's just that they put a 3-position switch on the control pin and then a 2 pin to Molex adapter on the power pins. I actually pulled those off so I could plug that fan into the motherboard chassis fan pins.

The other thing which was nice - everything is modular. To get out the holder for the fans, it's on a slotted rail. To get it out, you need to move the power supply - also nicely on a slotted rail. Take out the two screws on the power supply rail and everything slides out nicely - didn't even have to disconnect anything on the motherboard when adding the second fan.

The PCIE slot in the case lines up fine with the mini-ITX motherboard. Though I am using a single slot wide PCIE graphics card with only a passive heat sink on it, it appears that there's enough room between the slot and the case that you could use a card which is a bit wider - definitely not a card that would be 2 slots wide, but there is sufficient room that it could be wider than just a single slot.

There also is a slot for a slim-profile CD/DVD.

Not my first iTX build, but the 1st in this small of a case. I've been iTX building with WHS/*nix servers, and was impressed at what you can do with them so much that I decided to give a "real" iTX build a shot. I'm very surprised, and this case helped make it happen. My usage is just something to easily drag around which does gaming on 1140px monitors, some 2D AutoCAD, and watch movies.

To judge it's size, it has the footprint of a shoebox and just about half the height. My latest WHS2 case is a Fractal Array R2 and is a monster compared to this (but holds 7 3.5" HDD's, which is the point of that build).

What you'll be facing is a 150W PSU, one low profile expansion slot, the usage of two 2.5" internal drives, and a slim-DVD/BluRay drive. That 2.5" internal drive space is best for SSD's IMO as notebook drives are just very slow. If you really need capacity, then an SSD and a 500G notebook drive will fit nicely in this case. I went with a slim DVD drive, but only use it here and's really optional. The 150W PSU hasn't given me any issues and is actually a big PSU for it's class. Build specs are listed below, but it's not once hit the wattage wall given it's usage. It HAS failed while folding@home on the CPU and GPU which places both at 100% usage, but not all that often. I did F@H just as a test of sustained 24/7 loads and if the PSU can handle it. If I leave it folding, it might fail once a week while playing LFD2 when it's being starved. If I were not using a dedicated GPU and the i3's on-chip HD graphics, it'd chug right along IMO. It's also an internal PSU, so no wall or desk warts...just a normal cord to plug in. To get into any iTX build above 150W, you're really getting into cases meant for mATX.

It took 20 minutes from unboxing till the start of windows install. The case is very solid, relatively easy to work on. My only complaint is having to remove the cross bar from the HDD enclosure that goes over the motherboard. Some have removed it, I left it in because I wanted to tie the cables to it (keeps them out of the CPU fan). The case is just barely bigger than an Xbox 360 Slim or a shoebox, but since it's made of steel it is very sturdy. It also has large vents on the left side and two 80mm (only one is included) fans on the right side, but the lack of a top vent can cause heat to build up.

Update: I ordered a second one. I have one built for my mom using a Gigabyte H61N motherboard, Celeron dual core sandy bridge G530 processor, 8gb of Corsair XMS 1333MHz DDR3 memory and a 128gb Crucial SSD. The power load for this is very low, and as a result it is extremely quiet. Other than the dim blue light at the front of the case (which I like as it is hidden behind a cover and points down, so if you're using it as an HTPC or in a bedroom it would not be obnoxious) I have trouble telling if it's on or not. Their is plenty of room in the case, and with two fans on the side it runs in the high 30's while idle and high 40's at load. Never gets more than warm to touch.

My second build is what was mentioned earlier except with an Asus P8Z77-I(i5 3450s/HD6670). After testing with a Kill-A-Watt I found that it gets to about 120 watts at load. Above 100 watts I can hear a high pitched whine coming from the PSU, which worries me a bit. I only noticed this during benchmarking and it was never a problem while playing games. Also, the Asus P8Z77-I is a poor choice for this case for several reasons.
