    • Cooler Master HAF X

      I have had this amazing looking case now for three weeks and it has performed flawlessly. It is very quiet even though it has four cooling fans installed from the factory. With dual hot swap bays, nine expansion slots, two USB 3.0 slots on front panel, and support for four additional 2.5 or 1.8 drives. The case is also very roomy with plenty of extra space to install even the largest CPU air cooler. It is also water cooling ready. Excellent cable management ability. The only small gripe I had was that there is no 3.5" floppy bay, so you would have to buy an adapter if you really needed one. I have owned a bunch of cases and by far, this is the best I've ever had!

      Okay I haven't used this yet because I am building my own computer but the item is in perfect condition though FedEx did not ship it to me but let it sit in Dupont, WA for three full days before having it shipped by Ryder to my surprise. When the shipping truck pulled into my driveway and the driver opened the side door the tower's box was teetering on two other boxes ready to fall out the door. I caught it and noticed that the box had a huge hole from something smashing into it. Despite that, for all intents and purposes the tower looks very functional and has no damage. Shipping hell aside I would recommend this tower to anyone.
