I've got one in black, and the case itself is pretty nice, but there are some things that leaves more to be desired, such as the cheap volume knob which should be aluminum just like the Antec Fusion's volume knob, and a better VFD display. As far as heat, my E6300 (stock) idles at 35C, and 40-42C with Media Center running, the only heat issue I had was with the NB of my DS3 rev 1.0 which idled at 69C in the Bios, now its down to 46C with the Noctua NC-U6 on it. Overclocking probably won't cause any heat issues, and a Zalman CNPS9500 can fit, so that'll be a good heatsink if you want to overclock a C2D in the HD160, hopefully the P5B deluxe doesn't have a hot running NB like the DS3. Oh and the IRTrans software for the VFD is junk imo, the VFD serves no function for me so I just have it displaying "Welcome to HTPC" at all times.
Check out the OrigenAE X11 too just in case you're not a fan of a cheap basically useless volume knob.
