@magicc8ball Hey there fellow texan!! I just recently came across this thread and several other NZXT 810 switch mod threads and decided I just had to become a member! I been watching several videos and I think that most 810 switch case owners will likely want to get around doing 4 case mods which are fairly simple:
1) doing front cut outs for better ventilation/show off some LED fans
2) doing cut outs on the top, (I really like how another user HighlanderHD did his)
3) doing a cut out of some preference to the optical bay (Im getting a special edition and thinking of just dremeling out the middle that way i can still slide in something rather than cutting all out like you did lol)
4) cutting out a small pieces on the drive bays like user Letterkilled did (I believe you posted on thread as his build came along lol)
Now this is all I know so far that would benefit the case. I'm coming across problems in terms of getting the right power supply size and right radiator size for the bottom.
http://www.newegg.com/Product/Product.aspx?Item=N82E16817151109 this is the power supply I wanted to go with. I've only bought 2 items so far case and a gtx 590. As I know the 590 is power hungry I just wanted a power supply that could handle it with no issue. This is my first time building a PC and I'm trying to make sure I take my time and get it done right!
