This is my new personal rig and it is my 3rd PC that I have built for myself. I was fortunate to have gotten great deals on some of the new parts including the processor which allowed me to sell my old PC and almost break even on the new one. I am really happy with this build and don't think that I would change anything about it.
This build had a lot of new "firsts" for me including Micro ATX board, M.2 ssd, Individually sleeved cables and a large radiator. This is also my first time working with a Corsair case and I can't say enough how much I love the Air 240. The cable management is on point and the drives are easily accessible. Everything about it worked so well for me I am having a hard time thinking of anything that I would change about the case. I guess the only things weren't perfect was that the side panels are a little hard to put back on and the screws are hard to line up properly. I also wish all the dust covers were more easily accessible and magnetic like the side panel is. Another cool thing would have been to fit a slim DVD drive on the side like the Fractal design Node 804 has. My biggest issue is Corsair using a "tooless" design to secure the PCI cards. The problem with this is that I had to bend the latch in several places to create a secure fit. I would have preferred using screws instead which is much more secure.
The H100i V2 looks really clean and was a breeze to install. I had a H-70 in my old pc and the H100 was so much easier to install. I also liked how the tubes were much more sturdy but wish they still swiveled at the pump to allow for better tube management. The tubes were almost to long and was a little tricky to get them placed right, have the corsair logo face the right way and allow for enough clearance for the side panel to close. I also really like the build in corsair link and that the two fans for the radiator plug right into the pump as opposed to plugging into another mobo fan header.
I don't have much to say about the power supply other that I got on sale for 100 bucks which I think is a pretty good deal for it being platinum rated. This brings me on to the sleeved cables. I think that all kits from all manufactures are over priced at being 80 plus bucks. I also learned the hard way that cable kits are specific to the PSU model you have. I bought an EVGA brand kit for the EVGA PSU and when I tried to plug it into the PSU they would go in. I looked at the plug and noticed some of the pins were fused together with plastic. I used a razor and cut them off and then plugged everything in. When I went to power it on... NOTHING. I went around and around trying to figure it out and eventually plugged in the cables that came with the PSU and it powered right up. I probably got lucky I didn't fry any of my components. I did some research and realized I ordered the wrong part so I got the right one and put it in. I also highly recommend that if anyone spends the money on sleeved cables that you get some cable combs too. It gives it such a clean polished look and actually makes the mess of cables easier to work with.
