They sell it off in deals with monitors/peripherals for as cheap as it can be built by me or you without the monitor/peripherals. Often times you can even get a printer with it, or for cheap added on. They practically give the monitors away with the computers though, so especially if you need a monitor to go with it, or he still has an old CRT on the PC he is upgrading, Dell is the way to go.
The other benefit, especially if for a business, is the warranty. Sure, when you build yourself, the parts are warrantied, but you then either have to troubleshoot it yourself or pay someone to do so. You are also left with no PC for a couple weeks while waiting on RMAs and Replacement parts. With a Dell warranty, if the PC stops working for whatever reason you simply call Dell and get it handled promptly, not leaving your business short a PC for up to several weeks. The peace of mind is something you can't put a value on as a business.
Just my experiences when helping my Dad look at options for purchasing several office PCs for his business in the past.
