I am moving to Japan for 2-3 years and want to bring a small desktop with me for light gaming and to hook up to a tv for HTPC functionality. I am really looking forward to diablo III so performance for that is basically all I am looking for (I know it isn't a very demanding game). The PC needs to be small so that it can fit in my apartment and suitcase when I travel. I haven't built a Mini-ITX pc before but that was what I was looking at. It has been about 5 years since my last build of any kind so I am not up-to-date on current specs. I am looking at roughly the following:
CPU: Intel Core i5-2300 Sandy Bridge 2.8GHz quad-core (should I save money and go i3?)
RAM: 8GB (2 x 4GB) DDR3 1333
HD: 120gb SSD
Case: Maybe a Silverstone SG-06 with a 400W PS?
Video: Not sure what fits, whether low profile is needed
Motherboard: Maybe a ZOTAC H55ITX-C-E (leaning toward something with on-board wifi)
I could really use advice on what case, motherboard, and video card to go with. I am not sure if a low-profile video card is needed in all mini-itx cases, or what kind of power supply I will need.
Sorry I am so clueless. Thanks in advance for your advice!
