Corsair K70 RGB General Questions

[emcdawg123]

Currently I own a crappy 30$ gaming keyboard, and, as it's been over a year now, I want to upgrade to something more serious. I am also going to LCS on July 2nd, and I really wanna get my new keyboard signed by some pros! I was looking at the Corsair K70 RGB, but I have a couple questions that are holding me back from pulling the trigger. These questions are:

1) Is it easy to type on?
2) Is it really loud, or is the sound alright?
3) Is it hard to learn the software?
4) Really weird question, but is there aluminum on the bottom? I ask this because if there is then I can't get signatures from pros with a sharpie. If there's a substitute for a sharpie that I can use on aluminum, then I would appreciate it if I could be made aware of that as well.

Thanks for your help!

1) Yes, by my standards. Browns are a little easier than Reds.
2) Its a mechanical keyboard, so it will probably be louder than the 30 dollar one you have. Its not bad if you have a headset on.
3) The old software was horrible, the updated one is fairly easy. Make sure to get it from the website and not the CD.
4) The K70 is advertised as an aluminum frame, so I believe so. However, look at marking (or commonly called paint) pens: http://www.mscdirect.com/browse/tnpla/02598688?src=pla&cid=PLA-Google-PLA+-+Test&CS_003=7867724&CS_010=02598688&mkwid=%5B*GCLIP*%5D&prcid=%5B*GCLSRC%5D
They are amazing for writing on metal, we have plenty from an old job at a company that made street signs, paint pens mark them perfectly and last.
