[mythtv-users] Enough power?

[Jens Peter Vilstrup]

This might be slightly OT. Sorry if I offend anyone.
I'm in the planning phase of my MythTV project, but unsure if my
planned myth-backend has enough oomph.
I have:
Tyan Tiger MP with dual 1.4Ghz Athlon XP's and 1GB of RAM.
Gbit NIC.
2x PVR-250 cards.
Some yet-to-be-determined SATA(n) card(s), possibly RAID (that, or
software RAID).
A whole lot of harddrives.
MySQL will be on a different server.

I want to be able to record two shows simultaneously, while watching
on two frontends, while copying files at 100Mbit to or from a client
PC...
In your experience, is this a feasible goal?

Thanks in advance,
Jens.
