This was my first build ever. This machine will mainly be doing science work for a variety of distributed computing projects.
The case was a bit small, but I got everything to fit... barely. I had to do some plastic trimming of the Rosewill case fans with my Dremel to get them to fit around the PSU connectors and RAM slots.
I could have ordered one less case fan as the Corsair H80i water cooler was an after-thought and replaced a pre-installed 120mm case fan that came with the case.
System is stable overclocked to 4.4GHz. I'll be tweaking things slowly over the coming weeks.
The OS was free because I have a buddy that works at Microsoft, gets the employee discount, and owed me.
