1. I'd a wanted a MoBo w/ an industry standard 3 year warranty.
2. I'd run a 50 cable to the PC.
3. With regard to SSD caching .... won't do beans for ya.http://www.ukgamingcomputers.co.uk/difference-between-h67-p67-z68-and-h61-chipsets-a-22.html
Finally, another feature of a Z68 chipset is known as SSD caching which is where it allows the use of a small (say 10 or 20 GB) Solid state hard drive to act as a cache for a larger ‘traditional’ hard disk. If you are already planning the use of a Solid State drive this feature is redundant.
If you can’t afford a decent size SSD (40GB+) then there are more cost effective ways around using a small SSD and SSD cashing like spending less on a motherboard, (H67 chipset or even a P67 chipset) and putting the saved money into a decent size SSD.
