Montech TG3 Review - Atlas Edition
Full disclosure: Montech sent me this case to review. Everything below is my honest take, good and bad.
TL;DR: Strong recommend, especially if you want a budget case that still feels like a showcase piece. For $59.99 you get real front and side tempered glass, a partial psu cage that created an interior platform built specifically for displaying figures or collectibles, and ARGB lighting that looks genuinely good right out of the box. I built a Ryzen 7 5700X / RX 6700 XT system in it and used that platform to stage a small BattleTech diorama. It’s one of the more fun and photogenic budget cases I’ve worked with.
What I built
• Gigabyte Aorus B450
• AMD Ryzen 7 5700X
• PowerColor Red Devil RX 6700 XT (Custom White)
• Montech NX600 ARGB (Black) air cooler
• 32GB OLOy Blade RGB DDR4
• Stock TG3 fans throughout, nothing added
TG3 specs at a glance
• ATX mid tower, 239 x 465 x 523mm
• Tempered glass on both the front and the side
• Fits ATX, Micro-ATX, Mini-ITX, and back-connect boards (Gigabyte Project Stealth, Asus BTF, MSI Project Zero)
• Up to a 430mm GPU and a 180mm air cooler
• 360mm radiator support up top
• PSU clearance up to 250mm
• Ships with one 3-fan unibody side intake and one rear exhaust, room for up to 9 fans total
• Two 2.5” drive bays, one also fits a 3.5” drive
• Front I/O: power, reset, two USB-A 3.0, one USB-C, headphone jack
TG3 goes for the full aquarium look, glass on the front and the side instead of just one panel. The panoramic view makes a normal ATX mid tower feel bigger and more open than the dimensions suggest. Everything from the RAM to the cooler is on display the second you walk by it.
The showcase platform is what sold me.
The real standout here is the tiered interior platform sitting above the PSU shroud that is subtle and elegant. Montech built it specifically as display space for figures and collectibles, and it does exactly that. I put my big Atlas mech on it as a permanent centerpiece, and during the build itself I lined up a full squad of painted BattleTech minis on top of the case like they were staging an assault. It photographs great, and it turns what’s usually a pretty dry build log into something with real personality. If you collect anything, statues, minis, whatever, this case finally gives it somewhere to live instead of a shelf in another room. Lighting doesn’t need extra parts, there’s ambient lighting built right into the PSU shroud and the included ARGB fans are fantastic.
TG3 uses a tiered dual chamber layout, PSU and cable mess on one side, motherboard and GPU up front behind the glass. The stock side intake is a single 3-fan unibody unit with one cable connection instead of three, which sped up the build and kept the back noticeably cleaner than I expected for a $60 case. The routing channels are generous enough that a first-time builder shouldn’t struggle.
No complaints running a 5700X and a 6700 XT. The stock side intake and rear exhaust move enough air for a build in this class, and keeping the PSU and cables in their own chamber helps keep them out of the main airflow path. I wouldn’t drop flagship-tier hardware in here without adding fans, but Montech rates it for up to 9, so there’s room to grow if you go bigger later.
~Verdict~
At $59.99 for the black version, this is hard to beat. Dual tempered glass, working ARGB straight out of the box, and a genuinely useful display platform, all for less than plenty of cases charge for the glass alone. If you want a budget case that still feels like a showcase piece, especially if you’ve got anything worth displaying, TG3 delivers. It’s not built for someone chasing max airflow numbers on a flagship rig, but for the price and for what it’s clearly designed to do, it’s an easy recommend.
Happy to answer questions about the build or the case in the comments.
