      Great Case for a new build.

      The hard drives slide right in.... exact size left/right... put screws on each side to hold in place. Has cable management to hide cables.. Longer graphics card would fit, but I have a short card... You can order a 5 1/2 to 3 1/2 converter with matching black grill to install a memory card reader. Plenty of 120 mm fans for cooling.. 5 fans total. Top fan is larger...I installed an internal Antec/Kuhler 620 water cooler on back fan for cpu cooling... Because the power supply is on the bottom, the water cooler doesn't interfer with the power supply overheating. Other cases with power supply at the top, the water cooler would block the power supply fan and the heat would go right up into the power supply from the water cooler head and overheat power supply. Water cooler just fits...but you have to watch installation position .... so tight it was hard to get side cover back on.... would not take a larger water cooler. Have to buy 2 inch screws to install the water cooler.... originals aren't long enough. Get these at Lowes... has two standard usb ports in front but you can order case with USB 3. I don't have much use for USB 3 unless using a portable backup drive... I image with an internal hard drive. Has air filter for the front 2 fans. You will have to buy 3 extra 120 fans. The case has the right stuff and looks good and is easy to work with... I would buy another one in a minute. For $57 on sale, you can't go wrong. I tried other cases twice the price and the quality wasn't as good as Antec.

      This case is great and has a lot of room for easy installation. I was able to easily route the cables and mount the fans with a lot of flexibility. However, this is a very tall and large case. Wasn't expecting it to be that tall from the pictures.
