Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I have modded my Aria... let me tell you, this isn't like cutting into a nice thin piece of LianLi aluminum. The sides are plastic/aluminum sandwiches, which makes it a little nasty to cut into. I modded two Zalman Slim fans into the chassis, one on either side. This increases airflow quite a bit. I also cut out the card reader bay and inserted a LianLi fan controller that controls those two fans and my Zalman CPU heatsink fan. A veteran modder may find this easier, but for a novice like me it was difficult for it to be "nice" looking.
As for cables, there's not a lot of room in there. Just follow good cable management and do the best you can.
