That Antec is certainly not a bad case, and the PSU is most likely a solid option for what you have planned, but a
LIAN LI PC-V351B is higher quality and better looking (IMO) than the Antec.
Pair the PC-V351B with a
Corsair 400W PSU, and you have yourself a sweet setup that will last you for years to come.
If small size is your priority, I would skip the Lian Li PC-V351. The Antec NSK 1380 is *much* smaller. (I have both cases.) Definitely look at the dimensions before buying. I've got an ancient, huge Thermaltake tower for an old extended-ATX motherboard. The 351 is nearly 2 inches wider than that huge tower.
Also, the 351 uses 6 small screws to attach the side panel, which is just a simple sheet of anodized aluminum sheet. It's a nice looking system when assembled, but a bit painful to be opening on a regular basis.

---------
-Very small cube
-nonATX PSU (It's an Antec AR-350, 350W & 80+, replacements available for $40.)
-Mostly plastic panels, steel frame
-Full disassembly with 1 thumb screw (as I remember)
-One 3.5" external bay & 1 HD bay
-Fits retail heatsink, but might be noisy due to lack of open space.
PC-V351B
----------
-Large cube
-ATX PSU (I tried using a modular OCZ PSU when I got the case, and there wasn't enough room to plug the modular wires into the back of the PSU without chopping holes in the side of a 3.5" bay. A non-modular PSU was a much better fit.)
-All aluminum + motherboard tray
-Disassembly requires > 10 small machine screws (painted black)
-Four external 3.5" bays & 2 HD bays (I know Newegg just says 2x 3.5" bays, but look at the pic -- it's got 2 big bays on each side of the case.)
-Lots of room for a CPU heatsink & extra fans.
----other comments----
The Lian Li case does look nicer than the Antec case due to its pretty anodized aluminum panels, but I'd say the Antec case is a bit more rugged and better engineered. I think it's a bit of a cop-out to design side panels that are just tacked onto the case frame via sets of screws.
If a quiet case is a higher priority than a small case, the Lian Li is the way to go. Just keep those side panels from vibrating! If they're not screwed down properly, you can get a nasty buzz from the lightweight aluminum.
