I'm currently thinking of a llano A8-3800 machine, but I am having lots of trouble figuring out what a suitable case for my needs would be. I'd like to go with an integrated GPU and may wait for Trinity or Ivy Bridge, but I like to start my research early.
Personally i would have gone the Intel route with Pentium or Celeron, since they are so cheap and eficient, and probably will need less cooling, but if you want to stick with amd should be fine also.
1) Is reasonably small (the PC-Q08 is a bit too large for my taste, but something like the SG07 and smaller would be ok)
If you liked the looks and design of Lian Li Q08, but find it too big, then check the Lian Li Q11, it should be a little narrower and smaller, but a little taller, here are the dimensions
Q08 13.58" x 8.94" x 10.71"
Q11 10.24" x 7.87" x 12.40"
The Q11 can fit full ATX PSU, or if you use a picoPSU, you can fit a very tall heatsink like the Thermalright HR02 Macho
, according to thermalright specs, it supports, Socket AM2/AM3/FM1
. You might be able to run it without the fan and just the frontal fan.
2) Can power something like an A8 with 2 HDDs
Guru3d Review puts a peak of 110W for A8 3800, without optical and with an ssd, so in you case with 2x hhds i think you should be fine with something like Premium picoPSU-160-XT/16A 192W AC-DC
3) Has space for 2 3.5" hdds and preferably a full size DVD drive
The Q11 can mount 2x 3.5 hdds in the bottom tray and has a top slot for the optical drive.
4) Is reasonably quiet
Here will depend on your how much heat n load the setup will be into, but get a huge cooler like Thermalright HR02 and run it passively with just the frontal fan(depending on your mobo cpu socket they might align pretty well), i would probably change the fan for a Noiseblocker NB-BlackSilentPro PK-1 140mm x 25mm Ultra Quiet Fan - 700 RPM - 9 dBA
If you wish to see a how the Q11 works out with HR02, you can also the space for the hdds at the bottom, check mATX mobo in Lian Li Q11 mini-ITX build
