Antec One Hundred or Thermaltake V3

[fimble]

I could be in the wrong place here but the forum title mentions cases so here goes!

Opinions please. I'm looking to replace my current PC Case. Contenders are the Antec One Hundred or Thermaltake V3. I'm strongly leaning towards the Antec case.
Will I have problems with my MicroATX Form Factor ASRock G31M-S R2.0 and the I/O panel?

My current case is a very basic (i.e. cheap!!) affair that I think is made out of three layers of tin foil glued together!
At times it can set up a sonic resonation that sounds like a single cylinder diesel engine chugging. OK slight exaggeration, but all the noise is case oriented.
Looking at the specs I see they weigh in at 6.9kg Antec and 4.8kg Thermaltake. I take it that's the physical weight?

TIA for opinions.

Both cases support microATX.

I've never used a microATX board, but I believe that there's no difference between the I/O panel of a normal ATX board and a microATX one.

The weights are those of the empty case.

I'm not sure what to recommend. The Antec 300 is really popular.

Make sure to get free shipping, if you can.

Thanks for your input bobkn. I'm ordering a few things at the same time, if you spend over £75 the price of delivery drops quite a lot.
I can go next delivery for a very reasonable £5.99 for my eight items (inc. case)

You can't go wrong with either case. Although I personally think the Antec would be the better of the 2 given it has more options for fans/cooling.

Thanks society misfit. Just one voice to confirm my choice was all I needed.
