[mythtv-users] Backend Hardware Questions

[Brian S]

Greetings all,

Very Short Version: Do we think a Phenom II X4 B50 CPU stuck in a 
M4A87TD motherboard will have the ability to run well as a MBE & 
light-use desktop using an HVR-2250, 2 HDHR's, and 3 HDD's (OS on SSD)?

Long Version: After running a rather computery mythtv setup for a few 
years, I'm attempting to downsize a little bit, and am wondering if 
converting my desktop into the only backend is feasible - it seems like 
it would be, but I have a knack for overlooking the obvious sometimes.
Present setup is MBE w/HVR-2250 recording OTA + HDHR prime, SBE 
w/HVR-2250 recording OTA (two antennas - I live halfway between Chicago 
& Milwaukee) and then a FE only.

Was thinking I could move all BE's to an always-on desktop machine. 
Pertinent specs on the box in question:
CPU Phenom II X4 B50 (4 core, 3.1Ghz)
mobo Asus M4A87TD/USB3
8gb RAM (can bump to 16)

So the general idea here is to pull the HDD's from the respective BE's 
and add them to the desktop computer, add one of the HVR-2250's to the 
desktop, and then replace the other BE recorder with another HDHR (due 
mostly to cabling issues). The OS runs on an SSD. The mobo has 6 sata 
slots so I should be ok with all the HDD's. (I realize I will also need 
to do other steps with fstab & database and what-have-you)
The Big Question here is mostly just does the above machine have enough 
oomph to (theoretically but rather unlikely) record ~6 streams at 
once/run jobs/serve content to FE's while also being a desktop for 
mostly light-duty stuff? The only real CPU-intensive thing I can think I 
do is run virtualized windows XP for a few minutes at a time to scan 
documents to dropbox.
And I suppose Big Question #2 is there anything I might be overlooking 
here that means this won't work or is a Bad idea?
