Haven't been around in a while, but I recently took a swing at the MiniITX platform. Primary function will be HTPC, but it will double as a small travel friendly workstation. I'm going to Vancouver in a couple of weeks, so I figured now was a good time to build something like this!
Silverstone Sugo SG05B Chassis w/ basic 350W PSU
Intel Core i3 2100
2x2GiB Corsair Value DDR3-1333
500GB Seagate Barracuda 7200.12
When I go to Vancouver, I am nabbing the GeForce GTS250 from my office workstation to use in it, moving my GTX 560Ti from home to the office in case anyone needs to use that machine, and leaving my home tower off, I guess. I'm kind of regretting not going for the 450W version of the Sugo, but at the same time, fitting the 560Ti in that little case might be more trouble than it's worth.
I'll have more pictures later, when I nab the GTS250 this weekend to test fit it and get it running.
