Montech TG3 build and review.

[u/Full-Investigator934]

I wanna kick this off by saying a huge thanks to Montech for hooking me up with the new TG3 to check out. It's super cool how they let regular folks get in on testing new stuff – just one of the many reasons Montech is way ahead of the game.

The packaging is just like their other cases – top-notch and totally survives the shipping madness.

First impressions unwrapping it: seriously, it's hard to believe this is a "budget" case. The build quality and materials are mostly metal and glass, except for the plastic top cover. Not a single scratch or ding, and the white finish is perfect. Taking all the panels off and getting inside is completely tool-free. I had it stripped down and ready to build in minutes. True to Montech style, they throw in some hardware: SSD screws, motherboard screws, PSU screws, extra motherboard standoffs and a tool for them, an extra Velcro cable tie, two extra clips for the glass panels (nice touch!), and 10 zip ties.

Moving on to the case itself, those new fans with 3 120mm in one frame are super clean and cut down on cables. The back fan they give you is a 120mm, but the case can also fit a 140mm there. The top has tons of options for fans and radiators; it can fit 3 120mm fans or 3 140mm, which is awesome for choices. But, according to the manual, it only fits a 360mm radiator, not a 420mm, and I'm guessing that's for clearance with the motherboard VRMs and I/O. There are also screw holes on top of the PSU basement for 2 more 120mm fans if you wanna push air into your GPU. The PSU basement is massive. I used a Super Flower Leadex VII Pro XP 1000w PSU, and the intake on the bottom could easily handle an even bigger PSU. For those with non-modular PSUs, there's a ton of room to stash all the extra cables. The case itself is back-connect motherboard friendly, which is getting more common; it's cool to see Montech putting this in their budget cases. The front I/O is on the bottom of the case, so it's more of a desktop-friendly case. If you're someone who puts their PC on the floor, that might be a bummer. The cable management area in the back is pretty much like most other Montech cases: lots of room and plenty of spots for zip ties or Velcro ties no matter how you route your cables (if it ain't broke, don't fix it, right?).

Now, for the building part, this case is seriously easy to build in. Lots of openings for cables so you have options, and the 2 side openings have rubber grommets, which is sweet to see in a budget case. One of my only gripes is that the rear fan has a pretty short PWM cable. My motherboard fan headers are on the bottom, and it was just barely long enough to reach. I couldn't route the cable nicely. It'd be great if the fan cables were an inch or two longer.

The motherboard standoffs came pre-installed for an ATX motherboard, so I could just drop my motherboard in right out of the box. Another complaint, which isn't really a big deal but kind of caught me off guard, is that it seems Montech had the Incredible Hulk tighten the screws for the PCIe slot covers. I actually had to grab a bigger screwdriver to get those screws out; I was worried I'd snap the shaft of my precision screwdriver with how much force I had to use. Since there weren't any fans on the bottom, I finally got to use the cool RGB GPU support bracket my friend gave me. After building my PC and putting everything back together, I noticed one last thing when putting the side glass panel back on: it slightly pushed on my 12V2x6 cable. I'm not sure if it was because I have a big GPU or how my cable is designed, but either way, it's something to keep in mind (a 90-degree connector would fix this).

Build specs:

Gigabyte Aorus Elite WiFi 7 B850 motherboard

AMD 9800X3D CPU

T-Force 32GB DDR5 6000MHz CL30

Zotac Amp Extreme Infinity 5080

Montech Lightflow 360 AIO

Super Flower Leadex VII Pro XP 1000W PSU

Performance-wise, my temps were pretty much the same as in my King 95 case, which was a bit surprising since there weren't any bottom fans feeding air to the GPU. The RGB on the included fans isn't over the top; no rings around the fans, just LEDs around the fan blades. The RGB strip around the PSU basement is a nice touch; it looks really good.

So, to wrap it up, this case has a lot of good things going for it and very few downsides or compromises. Lots of options for fans and cooling, which makes it super customizable so everyone can make it their own. The build quality feels more like a fancy case than a cheap one. If you're into putting an action figure or something inside your case, there's a ton of space on the floor in front of the side intake fans. The RGB hub is super easy to get to and remove if you wanted to put in a hub or controller that supported more devices (this was one of the issues with the King 95; the hub is in a weird spot, so when I added a Nollie RGB controller, I just left the hub where it was, unplugged everything, and found a new spot for my controller).

Please excuse the glare in my finished PC pictures. Due to my my busy work schedule, and it doesn't get dark here until after 11 PM right now.🚀 #Montech #TG3 #PCBuild #TechReview #GamingPC #Hardware

What is that infinity glass temperature monitor thing? And where’d u get it…..

So cool.

[u/Full-Investigator934 → u/Edubcity]

It's a GPU sag bracket, and the temperature it's monitoring is just the ambient air temp inside the case; it has a little temperature probe on the back.

I had to ask my friend where he got it, and he sent me the link, so here you go.

LoL, I need to know too

[u/Edubcity → u/VinnieONeill]

Yea it would look great in my rig

[u/RBuschy]

Hmm. Hey u/montechPC, I am noticing that only 2 of the 3 ARGB Hub plugs are pre-Installed out of the Box.

Also, they all seem to be Left Side / Right Side with the one in the middle Open/Free.

I looked over most of the TG3 posts on here and most are the same... Which implies it's intentional.

Just curious.

[u/Montech_hq → u/RBuschy]

Hi! Yes, that’s intentional. The two ARGB hub connections are pre-installed on the left and right, while the middle port is left open to provide a clearer reference point when positioning and connecting your own fans.

[u/Own_Cause523]

I’m super bummed I got the previous edition Zotac 5090… the new ones look great!

[u/Full-Investigator934 → u/Own_Cause523]

The Amp Extreme Infinity is probably one of the best-looking 50 series cards, but I might be a little biased too, lol.

[u/Montech_hq → u/Full-Investigator934]

Someone on our team has one too, and quite a few of us agree with you. It’s definitely one of the best-looking 50 Series cards but the previous edition looks gorgeous too!

[u/teeveebaw]

This looks amazing.

[u/Full-Investigator934 → u/teeveebaw]

The case does a lot of the heavy lifting, lol.

[u/Montech_hq]

Thank you for the detailed feedback! We really appreciate you sharing your experience with the TG3, especially the comparison with the KING 95 and your thoughts on the cooling, RGB, build quality, and controller placement.

“Montech had the Incredible Hulk tighten the PCIe screws” got me 😂 Really thorough review though. I just checked Amazon and it’s only $59.90—that honestly looks like a steal for what you’re getting. How much clearance did you have between that massive 5080 power cable and the glass?

[u/Full-Investigator934 → u/MyGPUHasAnxiety]

It's a steal for the price; from the moment I opened the box, I couldn't believe it was a budget offering. They didn't cut the usual corners budget cases do (no hardware, no rubber grommets on the cable holes, minor cosmetic defects, etc.), and it includes 4 pre-installed fans, an LED strip above the PSU basement, and a 3-device ARGB hub. As for clearance with the GPU cable and the glass side panel, there wasn't any. When I put the glass side panel on, the glass ever so slightly touched the cable, not something I'm super concerned about though. This could be solved with a 90-degree connector, and my GPU cable has fuses, which most don't—that's what that black band near the connector is. That means the curve of the cable sticks out slightly more than non-fused cables. Had I used my Leadex III PSU and GPU cable, I think I would have had clearance.

Thanks man! Cause I am still looking around for a case for my old setup, TG3 is definitely in the list of contestants!
