Is my Dell up to spec to run ProTools LE well?

[Maud]

I have a Dell PC w/ the following spec's:

Windows XP Home Edition
2.4 gHz Pent. IV
1.5 GB RAM
30 GB available on a 60 GB 7200 RPM internal HDD
160 GB LaCie Exteranal Firewire Drive (for audio files)

Now, the reason I am asking this is that I want to also use the MOTU Symphonic Instrument V.I. which runs as an RTAS plug-in. To give you an idea of what I do, here is a basic example of what my sessions will be like.

2x Mono acoustic guitar tracks
2x Mono Acoustic stand up bass tracks or 1x Mono DI electric bass track
1x Mono vocal track
2x Mono backing vocal tracks
up to 4x Aux. percussion / banjo / harmonica / drums etc.
up to 3x MOTU Symphonic Instrument tracks playing solo string instruments (viola/violin/cello)

So we are looking at up to 12-13 tracks (worst case scenario) of simultanious playback during mixing with RTAS plug-ins. Plus the MOTU Symphonic Instrument Virtual Instrument RTAS plug-in playing some solo viola or cello.

To me, this sounds like a lot. I know I will have to tune up my Windows XP and make sure the Anti-Virus and internet are disconnected during recording. But in general this should all work don'y you guys think?

Thanks guys!
