That's a strong term - perhaps "incomplete" is better - true enough I did fail to mention you can upgrade your own RAM.
Hehe no offense meant and I'm sure you didn't omit it out of any ulterior motive
But I agree that Optiplex deal you show above is fantastic and in fact I'd recommend that over any of the builds we've spec'd out here. I run a small fleet of Optiplex machines and they're rock solid. The drawbacks are as mentioned - you won't be able to upgrade the CPU and also the case can be kind of limiting if you want to have more than two or three hard drives. But other than that I'm a fan of the Optiplex line.

DSMok you should take a very hard look at that Optiplex deal. It's going to end up giving you more machine for less if you can live with the aforementioned limitations of the case and motherboard (no overclocking, no CPU upgrading, limited hard drive space, proprietary motherboard mounting hole layout). Basically, if you are OK with getting a machine that you'll eventually throw away and never be able to upgrade it's core components then the Optiplex will be the most suitable option.
Upgradability is a sore point for the Optiplex, but if you're scraping a budget for a $650 computer, you're unlikely to splurge on a $250-400 CPU in 6 months' time.
The Optiplex 390 does only have 2 DIMM slots, but the base configuration comes with a single populated slot (1x4 GB). The OP can choose to add a second 4 GB DIMM, add a second 8 GB DIMM (intel memory controllers still work in dual channel mode with mismatched sizes), or go all out and get 2x8 GB DIMMs.
It does have a PCIEx16 slot so he can add a modest GPU for Photoshop work should he find the need to in the future.
PSU is only 250W, but it's at least an 80 Plus unit. It looks like the mounting locations are for a standard ATX supply, but without internal views, I can't be 100% sure.
