that ram kit with the blue led light ...what kit is that? spewing i bought my 16gb kit already LoL. I know you were going for a bmw build but it could be me i just dont see it. Not to say its not a gorgeous rig cause it is, just cant see BMW.
Possibly implement some leather into it somewhere or leather look-a-like (psu cover maybe?) Carbon fibre is on the mark! Maybe some "break vents" or "quad chrome pipes" like on the M3 perhaps some vents somewhere on the case with a mesh behind it...and perhaps a "chrome" style fluid for your WC'ing kit would be a color more in theme?
Oh and i know its kinda cheesy but a keyless remote start would be super cool! Anyways, just a few ideas to add to what is shaping to be a awesome build again man! let me know when you start wanting to sell of all your spare parts
Looks like a AVEXIR Core Series 16GB Kit to me? Thinking of getting this for my build aswell
