I'm currently shopping around for a combined media center PC / Oracle test box, must be the first time someone tried to combine those two in one box. And the first time someone plan to hook up a Oracle server to a television set. But they, there is a first for everything.
Currently looking at the new Intel Core2 processors. The 2.13GHz E6400 seems to be the best value for money. I wouldn't mind the E6600 with 4Mb cache, but the extra £67 can probably be spent on something that adds more value to the system, like an extra SATA disk to distribute the IO load. Not sure if AMD AM2 processors are a valid option anymore? The new Intel 965/975 chipsets are probably not supported in Solaristhough, where as a Nforce chipset probably works gret.
Found a quite decent looking case for the system as well, the Silverstone LC17.
I'll post a photo of sqlplus on a 32" LCD television once I buy the system. :-)
