Intel Core i3-2100T Processor 2.50 GHz 3 MB Cache Socket LGA1155http://www.amazon.com/gp/product/B004P8 ... PDKIKX0DER
$129 (adding shipping and export fees: $164.7)
Don't they allow combined shipping to reduce the impact of the fees?
FYI, they've got the G620 at 75$. It's got a larger heatsink like the 2100 which is better if your case is big enough.
In case you're planning to use the 2100T stock HS, make sure (don't "hope"!) your board can spin it relatively slowly. The noise becomes unbearable when it spins fast.
I'm tempted to buy a SSD, maybe 64gb (enough room for win7, office 2010, firefox 5, few other programs, and some files).
30G would be more than enough for lots of people. The 40G Intel 320s are decent enough for the price (they're supposed to be battery backed!). You can get more performance with a 64G like a C300 (not recommended for Mac or XP).
Howewer, in many mini-itx cases there isn't enough space for two hdds
Often times, there's enough room to tape an SSD somewhere. It wouldn't need to be mounted properly. There are also smaller SSDs. They don't have to be as big as a drive.
Would be safe to add a slim case fan or the stock cpu fan will be enough?
With your case, a case fan shouldn't be necessary but if have automatic fan control and you overwork the stock CPU fan, it'll get loud. A case fan should allow it to spin slower. Or if you don't want much CPU performance, you could underclock to keep the CPU fan from having to work too hard. But at some point, a Zacate or an Atom starts making more sense than a deeply underclocked Sandy Bridge. If you want the performance you paid for, a case fan would be sensible I think.
