Need recommendations on case/PS for small DVR

[RexxJ]

Hi, I've been out of PC building for a while. I want to build a small, efficient security camera DVR PC.

I have a couple-year-old gaming PC I'd like to re-purpose if possible. It is in a REFRIGERATOR SIZED case. So can someone point me to some good small options for small cases and minimum power supply options? This DVR will run headless and does not need the radeon video card.

Current tower case specs:

Item Weight 26 pounds
Item Dimensions L x W x H 8.60 x 17.30 x 21.10 inches

Existing components:

Processor 3.4 Hz Phenom II X6
RAM 8 GB DIMM
Hard Drive 1000 GB SATA III
Graphics Coprocessor AMD Radeon HD 6870
Graphics Card Ram Size 1000 MB

New DVR components:
existing ATX?? mobo
1 3.5in HD
power supply

I want to keep this thing as lean and efficient as possible. It will run headless. How small/low wattage can I go?

Thank you for your advice and recommendations!

I like the Corsair 200r. Not super small, but small enough. I recently built a friend an office/light gaming rig with the 200r and its a very nice little case. If you have big hands like me it is very easy to work with, while not being a refrigerator. Keep in mind that it has a USB 3.0 front panel so you will need to purchase a USB 3.0 to 2.0 front panel adapter depending on your mobo (Corsair sells one).

As for the PS... I am a big fan of Seasonic and Corsair (Seasonic makes it), just look out for a sale. Personally, I don't like nonmodular PS as I hate dealing with the spiders nest, but there are some very affordable ones. Lastly, something to consider is don't go too small on the PS. Its better to get a little more than you need and not use all the wattage then taxing a lower wattage PS at its max (running it out of its efficiency range). A 450-500 watt PS should be more than enough for your system.
