I tried to do the same thing but the problem is there are almost no 939 mobo with MicroATX form factors, that I have been able to find, and two gigs of ram may be overdoing it. i would stick with 1 gig maybe 1.5 gigs. There is a way to cool the temperature down but it requires you to modify the case. You could get two 120mm fans, use a dremel tool to cut the hole for it and use mounting brackets to hold it in place or you could even drill holes for the screws. i would suggest a silenx fan because the 120mm fans they have run at 58cfm and only 14dba. but two in the case one on each side, one intake, one exaust and you could definately cool down the computer. Also the Aria comes with a pci fan cooler. The power supply may be enough but i would not put more than a dvd+-rw drive and a hard drive (Aria supports up to three hdds), the video card, and maybe a wireless internet card; if you are going to be using a 939 CPU. but don't take my word for it.
