The parts that I have had with a prebuild is the CPU, the storage, and thats about it.
I love the motherboard, RGB and meant for overclocking, but a good reason why I got it is because of the insane speed it makes with the M.2 I have installed. It reaslly is insane for just an M.2 and also comes with pretty lights :)
The corsair vengeance is also some great RAM if you're looking at not too expensive ones for about 16 gig, they work beautifully and also come with lights, which I really do like lights.
This M.2 is amazing. I don't care about storage because I don't have my games sitting on there when they really dont matter in the first place about loading. I installed my OS on this and my computer restarts faster then my keyboard and mouse can boot up :). If you are looking for something to waste 100$ on, I would recommend a M.2, especially the 970 EVO, or PRO.
Storage is okay, they act like storage. The SSD does do its job comming from a pre-build.
This 1080 TI was definitly a step-up from a 1060 6gb. Ever since I had gotten this card, I had no issues with graphics and/nor needing to adjust a lot. This graphics card IS overkill, but its very good for its price.
The Liquid cooling is beautiful, and it preforms alright under load with a coolermaster fan. Note I will be upgrading to the LL120's here pretty soon.
The power supply is a little rattling, but does it job at 50 bux.
The fans are awesome, nice lights with aura sync, does it job cooling, and a very long lasting time for those fans.
I don't have the LL120's, instead I threw them on there and listed the price for the commander pro.
EDIT I finally threw in some LL120's and now everything is in synced with corsair Icue :) I love it
Overall this has actually been my dream-build of a computer. Lights and a really good CPU with a graphics card, It really is top of the line and awesome for what I have put into it, and really will kick-*** in any game pretty much :)
