I have one of
these which appears to have a very similar spec to yours, and Armory runs fine, although my password is about 60 characters long so signing transactions can take a fair few seconds (although I don't know enough about the workings of armory to guarantee that the two are related!)
Although, I am using the netbook only in Offline mode... You are talking about SSDs, which makes me think that you might be considering downloading bitcoin QT onto the machine, and the entire blockchain, and then using it as an "online" machine.
If this is the case, I would recommend that you do not do this.
I would recommend that you follow
this guide to set your netbook up to be a dedicated offline "transaction signing" machine. This will help reduce the risk of coin theft massively, as your private keys to your addresses never go online or on an online machine. This will also help, in that your netbook does not rquire any other software than armory, and no copy of the blockchain. It does though come with the pre-requisite that you have a second computer which you can use to store the blockchain (using nitcoin QT) and run Armory in "online mode", which requires at least 4GB ram (at the moment).
TL;DR, I use a very similar netbook for Armory in Offline mode with no problems (its perfect) - in online mode, I can't help you with; I don't think it would be suitable.
Hope this helps,
Bill
