Introduction, Specifications, and Pricing

I have said a lot of good things about Montech cases in the year or so that I have been at TweakTown, and today I have another case from them to review. All previous offerings I have covered have been built well, provided good value, and performed well in testing, so I am hoping that trend continues today.

The TG3 is Montech's new primary entry-level mid-tower ATX case, launching in black at $59.90, or white at $79.90. The black version features a two-tone interior color scheme, with a silver PSU shroud to contrast, while the white version matches the PSU shroud to the rest of the case. Despite the low price, Montech is including their GF U Series fans, with a 3x 120mm ARGB uni-body reverse fan to the front side, and a single 120mm ARGB rear exhaust fan as standard.

The TG3 is compatible with ITX to ATX motherboards, and includes BTF support, so you are certainly not short on motherboard options. An ARGB lighting strip is placed around the PSU shroud, and Montech is also including a tempered glass side and front panel with the TG3.

This is a case that Montech says is spacious, with a clean minimalist look to balance performance and modern styling. Looking at the specs, they are including a lot here despite the low price tag, so as usual, my job today is to see if it's actually worth considering as an entry-level ATX mid-tower.

Packaging

47

Montech gives a good overview of the layout of the TG3 on the front of the brown cardboard packaging. Black print is used, so no full-color premium packaging here to keep costs down on this entry-level case. A Montech logo and the model number are shown, with a slogan below. I have fed back to Montech that there is a spelling mistake for "True" here; this is also repeated in places within the review guide they have sent over.

Outside the Montech TG3

47

My first look at the Montech TG3, and immediately you notice the two-tone interior with the PSU shroud in silver. It looks good, with the sharp edges of the exterior corners contrasted with the curve of the PSU shroud on the inside. A black band surrounds the main tempered glass side panel.

47

The top features a plastic, single-piece vented panel; it does feel a little cheap compared to some of the other cases from Montech, but for the price I can't grumble too much. The vent fins are recessed with a filter included on the inside of the panel; I will show this later on the internal walk-around.

47

47

The front glass includes a black band around the edges, continuing the design from the side panel. I/O is placed at the bottom, well laid out, and includes the standard ports as expected. Left to right, there is power, LED control, headset audio jack, 2x USB 3.0, and finally a single USB Type- C.

47

47

Around the back, things are fairly plain, with vents included for the preinstalled fans on the side. No filter is included for the fans here, and being an intake, it will help not to restrict airflow, but may require some additional cleaning now and again.

47

47

47

The rear shows that the back, top, and front panels are tool-less; no thumbscrews are required, with the panels popping off as needed. Venting surrounds the main motherboard I/O area, and the pre-installed 120mm fan can be seen. There is some height adjustment available, while the rear can also be swapped out for a 140mm fan if required. Seven PCIE slots are included, sitting above the power supply chamber. Power supplies are fitted internally, rather than having a detachable bracket on the case.

47

47

47

Underneath the Montech TG3, you can see the power supply filter is fully framed. This is removed from the back of the case, so it's not the most easily accessible filter, but it's no hardship to move your PC from time to time to clean it out. The layout of the bottom means the filter is close to the bottom of the case, with the front area higher up. Rubber pads are included on the feet to prevent the case slipping around.

47

I am a little concerned about the clearance provided on the bottom of the case; only around 10mm is provided by the feet themselves, with another 5mm or so underneath to the start of the filter. Hopefully the power supply can suck in enough air to keep it cool, and proper maintenance will be required so it doesn't become restricted.

Inside the Montech TG3

47

47

Removing the top panel gives a good view of the interior, allowing you to accommodate 3x 120mm or 3x 140mm fans, or up to a 360mm radiator. The underside of the panel includes the filter, but it isn't removable for cleaning separately.

47

Taking off the side panel, the inside of the TG3 looks nice, spacious, and well laid out. Speaking of space, air coolers up to 180mm can be installed, while a GPU up to 430mm can be added. The back side can only support three 120mm fans or a 240mm radiator, and given its pre-populated design, it wouldn't make much sense to spend more and change these out. The power supply shroud includes cutouts to the back for routing cables, while it can also accommodate 2x 120mm fans to be fitted to the top for more airflow. The additional venting around the sides should help with the slightly restricted airflow from underneath.

47

47

The motherboard tray shows cutouts placed around it for BTF motherboards, while also having two cable pass-through points at the top and bottom for traditional boards. All these cutouts feature rolled edges so that cables don't get caught or cut when installing.

47

47

Looking towards the back of the case, you can see the large motherboard cutout and the drive sled mounted around the back, along with the rear GF120 U exhaust fan. A single 120mm radiator is also supported here. This angle also gives a good view of the curved main pass-through for the 24-pin connector and GPU cable, next to the side-mounted fans. Here, grommets are included to neaten up the finish.

47

The curved corner of the PSU should offer a contrast to the sharp corners around the exterior, and you can make out the included ARGB lighting strip that runs around the top edge.

47

47

In front of the PSU shroud is an open space that can be used for a variety of things. You could leave it free for a spacious, non-cluttered interior. Being able to accommodate a 360mm radiator to the top, and a 240mm to the side, you could use this space to mount a water pump to the front of a side-mounted radiator. Montech is pushing another route though, using the bottom tiered surface for showing off collectibles, rather like the GAMDIAS Atlas P6 CG I covered a little while back. While no spotlight is included here to highlight a figurine, it leaves the space open to use as you wish.

47

Overall, I like the interior on the Montech TG3. I agree it's quite spacious, and while aimed at entry-level builds, I can't see much issue with fitting a dual-radiator system into the case if you want to go with more than an air cooler or AIO.

47

Taking off the back panel exposes all the included wiring. Some cables are quite long, longer than actually needed, so some cable management will be required to really neaten things up.

47

Showing the rear sticker of the GF360 U Rev fan; having a uni-body design reduces the amount of cables needed to get them up and running.

47

47

For storage, the Montech TG3 can accommodate 1x 3.5" HDD, or 2x 2.5" SSD, so while not the most storage support ever seen on a case, it should be plenty for most end users. A single thumbscrew holds the drive sled in place.

47

Below the storage caddy is a small hub for the included ARGB lighting, being controlled via the case button on the front, or by software on your system. There are no additional ports, but I don't blame Montech for not adding more due to the price of the case.

47

250mm of clearance is provided for power supplies at the bottom of the case, so you won't struggle to hide cables with shorter units. Rubber pads are fitted on the bottom to sit the power supply on.

47

Wrapping things up before I install a test system, Montech includes bags with labels for the included screws, a spare panel latch, Zip ties, and a couple of Velcro ties. They also include a cleaning cloth and a manual, featuring the "Ture" issues seen previously.

Test System, Installation, and Finished Product

47

47

Throwing a system into the Montech TG3 raised no issues at all, with the space behind the be quiet! power supply used to hide cable slack. Montech includes a decent amount of tie-down points to clean things up, but as you can see, I have routed everything down the central channel, using the preinstalled Velcro tie-downs.

The front looks good, and the system looks quite compact, given the spacious area near the front side-mounted fans. One thing Montech doesn't include is a GPU support bracket, and I don't blame them. For the price of the case, if they had implemented one, it probably wouldn't have been executed very well, so excluding it altogether is the right move.

47

47

All built, with the glass back on and fired up, the Montech TG3 bursts into life, popping with the included ARGB on the fans and PSU shroud. While it looks great, it's the performance that matters, so let's see how it stacks up in testing.

The system I have built for testing includes an AMD Ryzen 5 9600X CPU, housed in an MSI B850 Tomahawk Max Wi-Fi Motherboard, paired with two sticks of 16GB Corsair Vengeance DDR5-6000 memory. Our CPU is kept cool using the be quiet! Dark Rock Elite. For storage, I am using a Corsair MP700 Elite 1TB NVMe M.2 drive. Finally, for graphics, I have an ASUS Prime RTX 4070 12 GB Super. Testing was completed with PBO enabled, AXMP1, and MSI Smart Fan configuration.

All testing was completed using Aida64 Engineer's System Stability Test v7.65.7400 for 2 hours. Other software used was HWiNFO 64 v8.32-5870, TechPowerUp GPU-Z v2.70.0, and CPU-Z v2.15.0 x64.

Kris' Test System Specifications

47

I wasn't sure how the Montech TG3 would perform in testing, but I was really happy with the results. Being the middle of summer, it's around 25 °C here today, so I hope that the positive pressure created by the three intake fans and single exhaust helps cram the case full of colder air to keep temperatures as low as possible.

Over two hours, the AMD 9600X hit a high of 77.1 °C with an average over the test of 74.7 °C. Looking at the data gathered from other cases I have tested, this places the case somewhat mid-pack between the Corsair 5000D and Montech's own Sky 3. This result is around 7 °C from the very best cases I have covered, but some of those cases do cost a lot more money.

GPU temperatures were better, though, hitting a maximum of 70.5 °C. An average of 69.7 °C means the Montech TG3 places within the top 10 cases covered, and it also makes me wonder how much of an improvement could be seen if you added two fans to the top of the PSU shroud, aimed directly into the GPU itself. It's another good result overall for Montech here, and with the prices of the case, it makes it very hard to ignore.

Final Thoughts

I said at the start that I wanted to see if Montech could continue the trend of offering well-built cases that provide good value and performance. The proof is in the build experience and testing results, and once again Montech has offered a case that is really hard to argue against, for an entry-level system or even a mid-tier one.

If you are not bothered about which color option to go with, then the black does make sense, given it's around $20 cheaper while offering the same in terms of features and performance. Overall, the Montech TG3 is built well, but you do notice some little things like the quality of the plastic on the top panel; it's certainly not bad by any stretch of the imagination, it's just not quite up there with more premium cases, and that is to be expected.

Support for water cooling is good, so if you want to explore that avenue you can, but I do think for many, an air cooler, or AIO, would suffice, and in conjunction with the supplied fans, would be more than a reasonable setup overall. BTF compatibility is a real plus point, and the ARGB lighting looks well implemented. Storage support is adequate, and the back of the case offers enough room to work with. I am trying to think of something that's a negative about the Montech TG3, but I really can't find anything to complain about.

One thing is True, or "Ture" (Sorry, I couldn't resist!), Montech has built yet another well-rounded case that you won't be disappointed with.
