It's a weird case, fam. 11/30/2019 2:27:09 AM

Pros: The spec sheet details exactly what you get.

This case is extremely ideal for at least one, and probably a few, niche computer builds.

Cons: Building in this case is hell. This is to be assumed implicitly at this form factor, but it doesn't hurt to say it explicitly.

The hot swap drive cages in this require 6-pin power and a mini-SAS SFF-8643 connector. That is one for each drive cage. This case should absolutely come with right-angle connectors for each of those. Straight connectors have such little clearance that I was worried about damaging the cables when I plugged everything in. Everything still works, but Silverstone definitely should have considered this.

Overall Review: TL;DR - This case is best suited as a single solution for people who need high-end desktop computing, mass storage, and compactness all in the same machine, particularly for game streaming and for compact workstations.

This is a really weird case. I'm not sure who Silverstone meant to buy this case. It is too large for most NAS uses and too constrained for most desktop uses.

For a NAS, unless you need a lot of expansion cards, m-ATX is excessive and adds too much size to the case. This case is also built to accommodate GPUs, so that adds extra size to the case as well that likely will not be used in a NAS.

For desktop uses, you will NOT be using a decent CPU without an AIO liquid cooler. Not because of thermal concerns, but simply because of cooler clearance. Specifically, the hot swap drive cages cover up the entire CPU/RAM region of the motherboard, leaving very limited space. I am using a Corsair H100i, which has a very short CPU block/pump. I was worried at first about it not fitting because of the tubes sticking up too much. There is no way an AMD Wraith cooler will fit. Even small Intel stock coolers might have some issues. In addition, even though you are mostly forced to use liquid cooling, this case doesn't have enough room to deal well with the tubing. I managed to get mine to fit by squeezing some of my tubing between the right hot swap cage and the right side panel. It is a very tight fit, but it just barely fits without pinching the tubing. This will depend on your specific cooler.

You are also limited to one GPU unless you want to sacrifice the possibility of using two 120mm cooling fans on the side of the case, which bring in crucial airflow for your essentially required AIO cooler.
So, if you want to build a gaming computer, you are stuck with one GPU and liquid cooling. At that point, there are "console" form factor m-ITX cases that will meet the same needs, taking up much less space and costing a bit less. The only benefit of this case is the hot swap bays, which most gamers will never need.

Workstation builds will face similar issues.

So this case is inferior to most NAS cases for NAS builds and inferior to most console/HTPC cases and standard m-ATX cases for general use builds.

So who is this case for, and why did I buy it?
There are two specific use cases that I can think of: game streaming and standalone workstations (ones that don't have access to mass network storage).

For streamers, this case can support a Ryzen 3900X with an AIO liquid cooler, a high-end graphics card, 800W SFX-L power supply to power everything, a video capture card for other game consoles, a HBA card to support the drive cages, and up to eight hot swappable hard drives for storing high resolution 60 FPS recordings - all in one relatively small computer.

Those same features also make an excellent workstation for certain applications, particularly anything requiring a high volume of local storage.

To be clear, a standard computer case + a separate NAS will be generally superior to the systems you will build in this case. What this case does is eliminate the need for a NAS at the cost of being very, very annoying to build.

Once the build is done, assuming you never need to get inside the case ever again, it will be painless from that point forward.

I don't think Silverstone will be making these for too long. I highly doubt they are getting enough sales volume on these to be profitable, even at the high price point. The use cases for this are just too specific. If you really want one, buy one while you can.
