Ok so here is the deal. I'm looking to get a new PC in January and just starting to throw around ideas. I will be moving to Japan after graduation and am looking for a PC I could potentially take in my carry-on on the flight to/back Japan and something that won't take up a slot of space when I get there. I have narrowed it down to three options. Let me know what you guys/girls think!
