I'm looking for cheap... I mean follow me on this one for a second....
MicroITX and NanoITX are expensive. Cheap is my main priority. It's not going in a car or anything, so 9.5x9.5 is an "OK" size for home theater integration. What I'm looking for is a case that is slightly bigger than this size that doesn't include spots for drives.
MicroATX Mobo = $40 Socket 939 + (My Old Ti-4600) or $65 w/ onboard Geforce 6100
Add in 512 MB of value ram ($40) and an old OEM ($50-$100) processor. I have a thumb drive already.
I've seen nice MicroATX cases w/ cold cathodes and temperature sensors and everything for $70 ish. (PSU Included)
I'm thinking in the range of $200 and use the parts I already have, or splurge a bit more for a tiny case if it exists.
Again, quality and speed come at a far second to price and size.
