Conclusion: The Dell Optiplex 780 USFF is an ultra-small form factor PC for the enterprise and SMB markets. Add a 22-inch monitor, and it takes up as much desk space as a mid-sized all-in-one PC. It's perfect for the space-constrained business user.
Pros: Compact form factor. Quiet. All-in-one-like monitor stand. Relatively simple to service. VPro. DisplayPort and eSATA port. Lockable. No Bloatware.
Cons: Monitor stand requires too many cables and connections. Locked down desktop has no access to eSATA. Wireless requires external antenna.
