There's also a spot to add 120mm fan to the front of the lower hard drive cage. For some reason though Antec decided to make it to narrow to fit a standard 25mm fan. I ended up installing an 80mmx80mmx15mm fan that I happened to have. This dramatically helped the cooling of the 4 hard drives I mounted there. By adding this fan my hard drive temperatures dropped a full 10° Celsius. Temperatures went from close to 40° to around 30°. A definite improvement and should help with overall hard drive performance and longevity.

There is also a shroud, I guess you would call it. It has a space for an 80mm fan to draw heat away from your video card and out the back of the case. I mounted a low speed Panaflo fan in mine just to help move a little bit of air but keep it quiet. Its placement is somewhat inconvenient though and will be especially so for enthusiast users as we tend to change hardware often. It's a bit too wide to use if you have a tall video card and it blocks access to the motherboard. In my case it blocks access to all the PCI slots and more importantly the CMOS clear jumper. If you are an overclocker you know how important this can be. The shroud installed with a fan really didn't lower my overall temperatures that much and they were well within margin of error. A 1° difference is not worth the hassle to me.

The front intake spaces are equipped with washable filters and can draw air from both sides of the case. There is a vent on both sides at the front. The grates are very generous for airflow and won't cause much in the way of restricting airflow or causing excessive noise. Even with all these fans installed and running on high the noise level is very acceptable. If I turn the TriCool fans to low or medium it gets even better as far as noise is concerned. This is a very quietly designed case.

The power supply placement at the bottom of the case takes some getting use to. Wire routing is generally very easy but it did require a bit of planning. The sliding panel between the lower and upper chambers is nice as it isolates the heat. Some power supplies may be a tight fit as was my OCZ PowerStream. Also some power supplies and motherboard layouts may be troublesome. If your PSU doesn't have very long wires it could be a problem. Some of my wires were just barely long enough. I have seen complaints like these on various forum boards with particular mention of the new modular types of PSU's. Another problem I had was that my video card (PNY 6800 Ultra) has two Molex connectors on the end of it. They were a very tight fit as the hard drive cage and hard drives are right up against the plugs. But it does work. I still have some wire management to take care of but overall installing the system was pretty straight forward.
