After taking a look at most of the outside of the case, let's take a closer look at the inside of the case.
We'll start where all of the storage devices will make their home. You have attached to the main chassis from top down, four 5.25" bays, two 3.5" bays and then another four 3.5" bays that are removable. Ample places to hold your drives.
The top has the steel plate removed where the DVD rom drive slides in. You just need to push out the front cover when installing your drive.
With the attached 3.5" bays, they have the top plate removed but that doesn't lead out to the front of the case. Removing the bottom one gives access to the 3.5" front panel push out cover.
That leads us to the removable 3.5" bays. Remove the bottom thumb-screw and push the release on the top and the cage slides right out.
On the top and the bottom the case are some steel guide feet and the top two bays have a screw-less drive holder installed. The image below shows the top two in the unlocked state, and the bottom ones locked.
If you need extra cooling they have a spot at the bottom front of the case that can hold up to a 120mm fan behind the removable drive tray.
Now on the backside of the case, you have the top area holding the standard PSU location. They formed a small shelf around the PSU for extra support. It is nice to have them if you ever change out the PSU with a full computer inside already. Below the PSU you have an 80mm fan (upgradable to 120mm).
The expansion slots have a quick release lock for each slot. Pull the tab out and slide it up to unlock and push it back down until it locks back in place.
The case comes with the standard screws and brass motherboard stand-offs. Something I have not seen in a while are the plastic locking standoffs that came with it as well.
The EPoX nf4+ board needed one of the plastic stands off since they had a limited number of the brass ones.
With the motherboard in place, and all external cables secured, I realize that it would have been nice to have some extra slack. Maybe 6-8" longer so I could have ran it along the bottom of the case. For reference, it is the light gray cable going from the front of the case to the back of the motherboard.
The size of the case is 440mm X 190mm X 445mm (L x W x H). As we see below, the GT3 case on the left is the same size as my 17" laptop, the Spire Blackfin case is in the middle and an older CM 300 Elite to the right. If you’re looking for a small mid-size tower case, The Spire Blackfin would be one to look at.
The Spire Blackfin case has the room to fit a standard sized ATX motherboard with freedom to run the cables up against the motherboard tray for better air flow. The front headphone / mic cable should be made a little longer to run along the bottom of the case and up the back under the cards.
The side air vent has a fan included with it that doesn't need to be on all of the time. When you’re gaming or pushing the system, you can have it open (on) or closed (off) when it is idle. The feet on the case could have been made better or designed with more than a simple rubber disk to keep it from slipping.
Thanks to Spire for sending over this sample!
