Used for work and gaming, but mostly Youtube.
My fan set up is quite efficient where there is barely any dust even after months of use being placed on my desk.
No problems so far.
I do have a list of parts lined up to further upgrade/fill in the desktop such as filling the 2.5' bays and maybe adding a WiFi adapter. Will definitely upgrade my GTX 970 that I'm using from my previous computer in this one to either a on sale/cheap liquid cooled GTX 1080 TI or a GTX 2060.
Also will liquid metal my CPU and overclock to at least 4.6 GHz depending on my silicon lottery.
Feb 28th, 2019 Update: Upgraded to a RTX 2060 and liquid metal'd it and have my CPU overclocked conservatively to 4.6GHz for now since it is not the bottleneck (also delided). Updated pictures with temperatures.
