I currently have the following setup:

# Akasa Infiniti tower
# Corsair 650w PSU
# GA-MA74GM-S2H (mATX)
# AMD 5050e 45W CPU
# 2GB OCZ PC6400
# LG BluRay reader/writer
# 120GB 2.5" 7200rpm 16mb Samsung System/Boot Drive
# 3ware 9690SA-8I PCIe Raid card
# 2x RaxMax RM-223 Drive cages
# 3x WD 1TB GP Grives
# 1x Samsung Spinpoint 1TB
# 1x Seagate 7200.11 500GB
# 1x Seagate 7200 1.5TB
# 1x Samsung 2TB
# Pinnacle 3010IX Dual DVB tuner
# Sil3114 4 Port PCI SATA card (just been in there unused)

Now they are all in JBOD under windows 7 at the moment, which dosent seem too practical as all my movies are spread out everywhere.

Now my original plan was to save up for a bunch of 2TB drives and put them in RAID6 under hardware (with SAS expander), but now im thinking maybe switch to *nix and using software raid.
As this will allow my to use different drive sizes? (is that correct?)
Slightly slower read performance, but as long as I can hit 100MB/s write I think I would be happy?
What read performance could I expect? What would it be like with mutiple people streaming HD movies (3-5MB/s) off it?
Whats software raid like with sleep/hibernate? I know hardware raid isnt too friendly with this

My second problem would be the TV tuner, as I use DVBlink for this under windows and share it out over the network. Would need to see if I could run a virtual machine for continuing this service

Uses for my file server:
Media streaming
VM Images (ideally need fast I/O for this as they are run on other machines over gigabit)
Backups of my work

My future plans are:
Ideally keep the low power CPU (could be bad move for software raid)
Upgrade motherboard, maybe one with nic teaming
Up the ram to 6GB+
SAS Expander card
More TV tuners

Any input would be great :)
