new AfterBurner network -- plz critique

So Im getting sick of 60+ hour renders, and got approval for a render farm, albeit on a shoestring budget. I'm looking at building the network below, if anyone has any suggestions on what would make it run faster, I'd appreciate it.

Severs:
3 Dell PowerEdge servers, each with a p4 2.8 (1MB/800FSB), 512RAM, and a 73GB Ultra320 drive, two 1000baseT onboard NICs. The source footage/workspace will be copied locally to the Ultra320 drive on each node before the render so theres no network roundtrip for input.

Network:
1 managed 1000baseT switch split into two networks, each dell will be attached to both networks. One network will include my desktop (Athlon64/1GB) which will act as the manager/monitor. The other network will link to the storage for output.

Storage:
1 Dell PowerVault with 4 250GB 7.2K RPM SATA drives in a RAID 5.
