I hesitated between the tower model and compact model but I'm happy with the choice, albeit cumbersome, but I was able to connect an internal SATA drive because connections exist (alim + SATA). However, it was necessary to the mechanics to fix the inside. It is very quiet and the performances seem correct. It takes a lot of patience to update the W8 and switch to 8.1. Ultimately, it is for backup data to an external drive with History Files and complementary system to the internal disk. With W8, I had to buy a Logitech webcam and Epson scanner because the driver 64b do not exist. I was pleasantly surprised to be able to install my old XP with OpenOffice Outlook! Now it's to do with time and use. The W8 is pre-installed but without reinstallation key ... Image backup essential system but I have not tested the relocation if the system disk grave ... Technical information very (too) brief.
