This was my first gaming rig that I built and it has really made me interested in building custom PCs and PC gaming.
I used the DIYPC Cuboid-R in this build because I noticed that it was very different and it looks awesome. The case was also very sturdy besides the front intake fan, more on that later. Another thing that I enjoyed about the case was that I could see through both side panels. The case also supports up to a 240mm radiator for water cooling. But the coolest thing that I saw when I looked at that case was that the motherboard was mounted to a platform and not to side of the case. There are also two SSD holders underneath this platform along with two slide out HDD trays. For a first time builder I felt like there was a lot of space for building and parts to fit.
One of the few problems that I had were that the front 200mm case fan died on me. So I had to replace it and the new fan works much better and feels much more sturdy than the other fan. Also, the SSD mounts are on a swinging hinge and that is held to the frame of the case by a screw. I had some difficulty opening the hinge to access the SSD brackets. The other thing with this case is that if you are wanting to use the 5.25" bay be careful. The drive bay holder will not fit easily if you have a large GPU. You may be able to get past this if you go with the R9 300 XFX series GPUs since they are slightly smaller.
