I purchased the Thermaltake TR100 SFF Chassis for a new compact build in 2025, and I am quite happy with the case. My previous model was the V1S which was nice but wanted a different config for my new build. First off, the olive color is nice. It looks even better in person and gives my setup a sleek, modern look that stands out from the usual black or white cases. The small form factor is exactly what I needed. It saved a ton of space on my desktop, making my whole work area feel much less cluttered. Despite its compact size, I didn't have any issues fitting all of my components. I was able to easily install my Thermaltake AIO cooler and even an RTX 4070 without any clearance problems. I do appreciate the magnetic panels. They make accessing the components incredibly easy for installation and maintenance. No more fumbling with tiny screws just to pop the side panel off! Overall, this is a great case for those keeping their build minimal and have the right components to fit it. It looks great, saves space, and is a breeze to work with. I would definitely buy it again for future builds.

Im glad i purchased this itx case. Even though there are other similar ones under 100, i feel the extra 40 dollars spent on this is worth it Pros - metal case made of steel! There is a weighty feel to it and to me thats a good thing. -constructions and holes are all well aligned -easy instructions to follow Cons -might be abit on the heavy side for some I just dont like those cheap feel of light aluminum body chassis in most of the itx cases. If you want quality case, definitely give this one a look. You might be able to get this for abit cheaper when it is on sale

This is 4.5/5 in reality, it just wouldn't be fair to place this in a 5 star category. So why the 0.5 star knock down? Simple, the internal power extension cable. The extension cable is pretty standard for this case. There's nothing wrong with the 90 degree bend for the PSU, that functions perfectly, but the direct port to the back is not great and generally gets in the way of a 280mm AIO with THICK fans. Stand fans over all (25mm) aren't affected and I suppose that was the idea, but if you want the best airflow through a radiator in a cramped space and you notice there's plenty of room, once you remove the extra riser cable slack/retention bar, to place a 30mm fan you're going to opt for thicker fans, right? Well that's what I wanted do once I replaced the riser cable with a slightly shorter one and removed the pointless retention bar. But now, the power cable with in the way. This required me bending the absolute crap out the cable to bend 180 degrees towards the case and use zip ties to force the cable to bend more naturally out of the way of everything else i the case. Overall, it looks amazing when I open it and way more natural, even with the unnatural bend, than the way it comes as a default. Unfortunately, this also meant I had to shave the rubber off the edge of the cable to get the bend in the first place and truly recess the cable as close to the rear of the cast as possible. This was a bit of a pain and it simply doesn't make any sense why the power extension isn't a 90 degree to 90 degree out at the rear. It would make the case overall easier to work in and pretty up the cable management by placing it along the bottom of the case, completely out of the way of all parts. Anyway, this was the one major flaw of an otherwise flawless case. Everything else about this case is testament to the quality I've come to expect from Thermaltakes latest cases. The removable GPU slot makes for a far easier installation of these exceedingly larger and larger GPUs. Routing and tucking your cables is made so much simpler with the removable PSU tray. The only other critique I could make was the lack of mesh on certain areas depending on your choice of air flow overall, but that was easily fixed with my own mesh and magnets. The fan capacity is fantastic and is truly a major factor on why anyone should consider getting this. Unlike the large majority of ITX case, which to be fair are going for smallest optimal space, this offers the ability to use a full 280 radiator so you won't be limited on your CPU with that capability. 9950X3D? Keep it coming. 14900K? Your golden, so long as your CPU isn't toast already. Heck, I was even able to install the highly functional/high inconvenient Corsair H115i Titan and even had enough space to hid the iLink Hub out of the way. The point is the this case has the space. Additionally, build quality is impressive. At no point did I feel it was too flimsy or would easily bend from simple disassembly or some light abuse. The Metal panels are fairly thick, but light and they're held on with heavy duty magnets. The top and bottom grates slide into place and are held down with thumb screws. everything about this case is about making maintenance extremely easy in the future. It's definitely not the smallest ITX case you can build but it will certainly be the most convenient you'll be able to find. Thermaltake has certainly stepped up there game these last few years. They started listening to criticisms and making the appropriate changes to all of there current cases. So much so, they are an instant go-to when I'm researching a build. Can't say the same care was taken with their AIOs, but I think I just have bad luck in the department. Additionally, Thermaltake is clearly having fun with the variety of color schemes they've managed to make. I simply love the fact that you could go into a store full of their cases and it would be like walking through a candy shop. TLDR: Sturdy build, easy to work in, some draw backs to the extension cable, plenty of room for cable management, fans, and cooling.

Awesome little case! I was drawn to these with the cool color options and small size and it was perfect for what I needed. The parts layout is unique but nothing too terrible. My only wish is it fit hdds but I understand why not with the size constraints. Despite being so small the cooling and cable management is pretty good too.

This is overall a great PC case, it has a good spot for the GPU with plenty of room for a large 3 slot GPU as it says. Like in many mini PC cases, you have to do a bit more planning for the cable management as it can be a bit tight. Airflow is great. One reason I only gave it 3 stars is because it doesn't have a mesh or dust filter on the bottom or back of the case, and that obviously allows bugs or dust to get in. Of course the air holes are larger than many other cases. It didn't come with any extra mesh or dust filter so I have to figure that out.
