Advice on config for NUC barebones system

Hey guys,

I need some advice about component selection for a HTPC I'd like to build based on the following NUC model (my hardware experience so far is limited to RAM upgrades):

How do I go about choosing an appropriate SSD, RAM, etc? Which manufacturer? What capacity? Also how do I get bluetooth in it? Is that chipset included on a WiFi card? I don't really want/need WiFi necessarily, but I imagine bluetooth may be useful at some stage for my input peripherals 15 ft away on the couch.

Thanks a lot,

Mark
