Well the other combo is no longer available so your answer should be the Lian Li and Antec HCG by default. Don't worry both Lian Li and Antec are both reliable and quality brands. I have a Antec 300 along with Antec Earthwatts 650W no problems so far.
I can definitely vouch for the Antec HCG 750W but as for the Lian Li.. it is a good brand and they do have lots of quality cases.. but that's mainly up for you to decide if you like how it looks. If you hate it, you can always get the HCG for $70 after MIR, and a Rosewill Challenger or Antec 300 ($50 after $10 MIR).. or anything in that range
