This is a repost of a recent deal for these Acers but they are now showing as 280 in stock at the time of writing.
I ordered one before the deal had been posted last time and have just had a dispatch note so it looks like they have had a delivery.
Note these are the R3610, not the R3600 like it says on the site.
They have optical audio and are the Dual Core Atom 330 CPU's.
I would recommend selecting the next day delivery option (it's pretty pricey though!) to try and ensure you get one as they don't seem to allocate stock based on time of order, it's done by dispatch priority.
