tempered glass panel

The Forge 100 Series offers a thoughtful case design that allows users to easily install or remove the tempered glass with ease. It uses screws that are easily fitted and the glass can be put in place without much hassle, offering a safe and simple process.

Built for Prime Fan & Radiator Capacity

STYLISH 4MM TEMPERED GLASS PANEL The MAG FORGE 100R offers a plethora of ways to install fans and radiators so you can optimise your cooling. It comes with two 120mm RGB front fans and one 120mm rear fan pre-installed to kick-start your cooling.

MSI MAG FORGE 100R, Black, Mid Tower w/ Tempered Glass Window, 3x 120mm (2x ARGB) Fans, USB 3.2 Gen1, ATX/MicroATX/mITX is rated 5.0 out of 5 by 5.
Rated 5 out of 5 by from Amazing case for beginner builds. I had terrible experiences working with GameMax cases and thought i'd buy a case from a more known brand, Msi. If you are new to the aRGB scene (as i am), you will be delighted when purchasing this case, as it simplifies the process of connecting all the cables up. It's powered via a SATA connection and to utilise the aRGB features, it's plugged into the jrainbow slot (or 3 pin aRGB header) which can then be used by programs such as Mystic Light. The fans are connected to the motherboard via 4 pin headers (make sure you have 3 sys_fan headers!) Pros; - Instructions are very clear to follow, anyone with common sense should be able to follow the instructions and finish your build with no issues. - The case feels like it has a great build quality, the metal doesn't feel cheap and flimsy and the tempered glass window is a nice tint which really shows off any RGB that you may have. - The case it self looks quite professional and cool, which really helps create the theme of building a powerful gaming PC. - The two aRGB fans in-front are amazingly bright and powerful, with a large array of colours, selectable via Mystic Light or the LED switch on the case. - Two USB 3.0's provided on the top, pretty standard in cases these days. -------------------------------------- Cons; - The tempered glass side panel could smash if you try to take the panel off vertical. Make sure it's lying flat on the table if you are going to check the build. - The PCI slot covers are not screwed down. You will have to manually remove it to slot in your graphics card. There are two replacements provided via the case if you need to put them back. -------------------------------------- End of the review In the end, i really enjoyed building in this case. For the two aRGB fans and one non-RGB fan in the back and one RGB controller, you're really making your moneys worth with this case. Good luck with your builds if you choose this case!

Rated 5 out of 5 by from Great case for the budget I spent a fair bit of time researching case options for my first budget/intermediate build (approx £700 total) and in the end went with the Mag Forge 100R. I am extremely happy with it. Pros -------------------- * The build quality is excellent. Nice tempered glass side panel. Metal panels are study and feel good quality, and thumb screws all round make removing them very easy (although no hinge on the glass panel so some care is advised). * It looks really great. I was a bit apprehensive before ordering, but I really don't think that the pictures do it justice. Could not be happier. * Comes with three fans, including two with ARGB, which is very good for the price. The front panel has two large mesh sections so great airflow. Note: while the ARGB lighting can be controlled via a button on the case, to take full advantage of MSI's Mystic Light, and a world of customisation, a motherboard with an ARGB header would be best. * I have not built in it yet (waiting on other parts) but it seems very roomy inside with lots of cable management routing options. * Standoffs preinstalled for mounting the motherboard, which is not always the case for cases in this price range. * Two USB 3.2 ports is nice and definitely not a given in this price range. Cons ----------------------- * There is a dust filter on the base for the PSU, but this is difficult to access and feels a bit flimsy. * You have to break off the PCI slot covers to install a GPU, etc, which seems a bit wasteful (although they do include replacement covers) * The instructions provided are very basic and do not seem the most friendly for a total beginner, however there are countless videos and other resources on how to build a PC so this is a minor point. * Very minor point: but "in my case" (pun intended) the bag containing the accessories had split (I assume in transit) and I had to hunt around inside for a screw. No big deal though. Summary ----------------------------- Overall this is a great case in it's price bracket. For me the standouts are the mesh front panel (great airflow), three fans included, ARGB controller and the general look of the case. For these reasons it is a fantastic option for a budget/intermediate build, and I genuinely think difficult to match on features alone.

Rated 5 out of 5 by from Fantastic Case Bought this case for a first time build and I can say that this case is more than I expected. Additional ARGB features that I could only find on more expensive cases. Easy to build in and good cable management. Would definitely recommend this case.

Rated 5 out of 5 by from MSI brings premium features at a budget friendly price Aesthetics 5/5 A wonderful looking case, what can I say? The included ARGB fans at the front of the build with the mesh front panel shine the light easially through which makes them super bright and vibrant. The rest of the case manages to have gamer undertones with the edges at the front and the MAG styling on the power supply shroud but it isn't loud unlike some other cases on the market. The inclusion of tempered glass instead of an acryllic side panel also makes it look very premium and nice. Hopefully MSI continues with this quiter gamer aesthetic as I personally quite like it. The colour matching of the plastic front panel and the rest of the metal chassis is good and hard to tell the difference. Features 4.5/5 For a £60 case it executes the things it tries well. The ARGB hub on the back of the case has a lot of headers on them. Although it is a bare PCB, it is attached with a foam tape which gives me the security that it wont ever short because of the metal. The 2 toolless 3.25" bays are smooth and easy to use. The frontpanel ports and buttons are very nice. The buttons are very clicky but the power button isn't the smoothest I've ever seen which is a minor complaint and can't be that hard to improve on their next cases. Durabilty and packaging 4/5 The case is covered in a clear plastic bag with white foam protecting it and put in a big brown box. Bog standard. It deffinitly protects the case during transport and it serves its purpose. You don't really require anything else. The included screws and other nick nacks are held in a resealable plastic bag, nice touch. The actual case it self seems very durable and the thickness of the metal is okay. Although one thing I paticulary dislike is the disposable PCI-E slot covers. I haven't seen them in years but MSI has included them in this case. I do get it's a budget case and 2 extra PCI-E slot covers are included if you need to reseal the holes but it is 2020. Even other budget cases include replacable slot covers. Build expereince 5/5 It's a simple case and so is the building experience. No fiddling around with anything and it just worked. The back panel cable managment space is alright. I can't really say much else about it because there were no highlights or downsides to it. Personally the more expensive cases with fiddly cable managment gimmicks are worse than this case because it just does the job. Preformance 5/5 It isn't hard to make a well preforming case and MSI has done it too. A mesh front with lots of fan slots available, minimal obstructions included. I didn't include any extra fans as the 3 included ones are good. 2 Intake and 1 exhaust which gives the case positive air pressure, the best air pressure. They all push lots of air at a quiet volume. Conclusion MSI isn't a brand I first think of when I think PC cases but this entry to their case series is an excellent one, it's simple but includedes more expensive features like ARGB which is executed very well. Some slight quality improvements can be made but they barely affect the experience of using it and I only say them because I am having to use a critic's eyes. YES I WOULD RECCOMEND THIS CASE TO ANYONE!
