I found an Asus 650VT on Craigslist for $500. This is by far the best deal I've seen on CL lately. I'm going to suck it up and buy last generation hardware - the newest lineup is sexy but the only hardware intensive thing I'll be doing is playing SC2 and compressing the occasional movie to watch on my phone. This brings me to my question. What should I look for when I'm checking out the laptop before I buy it? I'm planning on running Memtest86+, and doing some stress tests to make sure the temperatures aren't insane, as well as entering BIOS and confirming that nothing is overclocked (not that it wouldn't be easy to clock back to factory settings before showing the laptop off). Is there anything else I should check for? Are there hard drive diagnostic tools?
