My opinion, (which is not an expert one) is that straight away I'm put off by the Intel cpu... but that is a matter of personal opinion which is probably not best discussed here, huh?
My advice would be to look at PCWorld, Staples, Currys (some really good deals there!!!) and compare features/price. This doesn't include a monitor, remember (at least I don't recall seeing it)
EDIT: One other point... Backup support. If it fails, you won't get a replacement as no doubt it is a limited availability offer. What are Aldi like on honouring refunds etc if it fails (question, not statement).
Just because something is cheap, it doesn't guarantee it's a bargain.
