5.0 out of 5 stars Cooler Master H100 Case Review - A Real World User
Reviewed in the United States on August 21, 2019
This case was released this year and I pre-ordered the case here on Amazon due to wanting a small portable mini-ITX machine. Yes this is a limited field and a lot of the cases have been out for awhile and have had no major updating. While I was looking at this case there were many things that I liked about it and some that I was unsure about. After watching several YouTube reviews I really started doubting my choice in purchasing this case, I even tried to cancel at the last minute but it was too late. So it was delivered today (08/21/2019) and I decided to give it a shot and see how it does.

So first impressions is that it is smaller then I thought it would be since many reviewers considered this case big and bulky. They also stated that it felt cheap and not well built. However in my experience this case felt very solid and well built and was smaller then I imagined (it really is hard to tell on videos).

So I started my build and here are the specs:

Case: Cooler Master H100
CPU: Ryzen 5 2600X
CPU Cooler: Noctua NH-L9a AM4 Low Profile Cooler
MOBO: ASUS ROG STRIX B450-I Gaming Motherboard
GPU: PNY GeForce GTX 1660 XLR8 OC Single Fan
RAM: Corsair Vengeance LPX 16GB DDR4 DRAM 3200 Kit - Black
SDD: (1) Intel SSD 660p Series 1TB M.2 Drive and (1) WD Black 500 GB M.2 Drive as boot drive

I assembled the MOBO outside of the case to include the CPU, CPU Cooler, both M.2 Drive and RAM. This was extremely easy and didn't take much time to do, I have built multiple gaming PCs in the past. If this is your first time it will take a little longer but isn't difficult at all. Next I secured the assembled MOBO in the case and connected the from connectors and the fan and RGB cable to the MOBO, I did not have to use the included RGB control since my MOBO supported the RGB fan. I did you the included cable from ASUS for the front connectors and it made it very easy and fast!

At this point I started my cable management, this case requires you to take time and find good locations to secure the cable to so that they are not blocking the main fan and are out of the way of your other cables. The case comes with several cable ties but I found those a little thinner then I licked so I used my own cable ties.

Now came the part to start installing and routing the power cables. I highly recommend that you do not use any HDDs or non-M.2 SSDs since this would make cable management much more difficult. I did use a regular PSU and I would highly suggest at least a semi-modular PSU but it was do able and not that difficult, just took some more patience and time. Once you connected the power cables (24 pin connector and the CPU connector) I slide in the PSU and started to route and secure those cables. It came apparently quickly that using a regular CPU cooler and not a low profile one would not be a good idea as there would not be a lot of room for the fan to pull air from.

Once this was done I secured the PSU into the case. Then installed my GPU and routed the power cable and secured it.

My thoughts on this case are my own thoughts and are based on building in the case. This case is underrated and provides a great case to build in but requires patience and time in building which all mini-ITX builds take. I have used a ThermalTake Core V1 in the past and I feel like this case is built much better and will stand to be moved around and used. The side panels are less flimsy and are secured better. The looks on this case are great and the handle could use some redesigning such as removing the ridges and perhaps use a honeycomb pattern for grip.

The RGB fan is very quite and the colors are very even and bright. When testing the system temperatures were good and did not overheat however time will tell if the thermals are good on this case. This is an initial review and I will update it if needed in the future.

I would recommend this case if you are looking for a portable mini-ITX case, there are ones out there that look better but they are not designed to be transported around. If they have acrylic or tempered glass sides then they should not be used as a portable machine since they will get scratched and or broken. But if it sits at home all the time and you are looking for a beauty queen then consider another case. This is a functioning workhorse / gaming PC case that I expect will hold up very well to daily use and frequent travel.

If you have read this review then you are seriously considering purchasing this case, then go ahead and purchase it and give it a fair try!

Reviewed in Mexico on June 10, 2020
El diseño resulta más bonito de lo pensado así como ser resistente, es también muy compacto, casi como una consola y cargarlo con su manija es posible, no me gustó la tornillería y el cerrado de la caja no se sienten tan durable los tornillos de mano ya que entran un poco forzados, fuera de eso es muy bueno (está opinión la hice sin haber realizado ningún ensamble en la caja)
