friends have been asking about HTPC and Network Media Tank (NMT) like Dune, BD1, etc etc.
and though NMT is good, they're still an embedded system with a processor and an OS (in the form of firmware). some of the better ones (NMT concerned) runs of general purpose CPU (ARM or RISC compatible) with a form of general purpose OS (linux, windows CE etc).
and since the price is just a bit more from a full fledged system, why not consider a HTPC?
the same general purpose OS, with better components (system components).
the same general purpose CPU, with better speed.
the same general purpose hardware, with better upgrade path.
i'm running
Silverstone LC17 HTPC case. RM400 and fits 6 HDD in standard form.


drill 8 holes and you'll be able to fit 8HDD if your mainboard has the clearance. mine does.
don't use the 5.25" optical drive bay?


buy a HDD cage and put the 2 extra bay to use. able to fit 3 HDD here. i ripped mine from an old computer case.
still require more storage? there's space for 2 more HDD beside the cage.


so that makes 13 HDD in a single RM400 case.
still require a BDROM drive with all of that? easy, can always use an external USB-SATA converter. or eSATA converter and run in externally. when all of your movie collections are stored in the HTPC, browsing and selecting and watching are easy peasy. don't need to search the list and swap the hdd manually. everything are done with a remote from the couch. no need for an extra NAS or another PC acting as a file server. no bandwith problem handling high bitrate file or bluray playback. no lag from the network.
and then there's support for internet browsing, subtitles searching, subtitle syncing, music playback (with support for external DAC/soundcard), remote desktop, bittorent, download, etc and everything else you can think of.
the cost?

RM400 for the case.
RM350 for the CPU.
RM400 for the mainboard.
RM150 for the RAM.
RM300 for the power supply.
that's for core i3 with gigabyte H55M-USB3 with 7 port SATA and USB3.0 support. good mainboard with new processor.
if you don't mind settling for older generation LGA775 core2duo, the cost is lower.
RM400 for the case.
RM200 for the CPU (c2d e5400)
RM370 for the mainboard (MSI p45 neo3-fr) 8 port sata with 4 port pci.
RM136 for the ram (2gb ddr2)
RM300 for the power supply
RM165 for the ATI 5450.
both are capable of HD audio bitstreaming.
