Ok so you wanna prefer to buy the assembled hardware and then configure the OS and XBMC on it ... right.
Lets start with this ... with a budget of 15-16K this is a steal deal ...
Zotac ZBox nano Plus ........
I am recommending this product for people who want an HTPC
without the DIY route. Its has all the features for a decent HTPC. would play all HD content will full
HD audio Bitstreaming.
It has inbuilt
wifi n and bluetooth. Comes in a small form factor and should fullfuill all your requirements most of all it full fills all you points and requirements you have stated above.
Since its a PC you can pretty much install anything, including XBMC,
Its plug and play, all you need to do us install windows, install GPU drives, install XBMC.
This was AMD APU platform, we you wanna go Intel Sandybridge way then this is what I will suggest ...
Any Intel H67 micro ATX board. I will suggest Intel
DH67BL ... The board is around 5K maybe less.
Couple it with an
Core i3 2100 .. again not more then
5K
Add 4GB RAM ...................1.2K
1TB HDD ......................... 2.5K
Misc (cabinet keyboard mouce ...... 2K
Total :: 15700 and this might be a 1K or 2 more as I dont have the exact price of the Proc and Mobo.
A bit expensive coz we have gone latest Intel Sandy bridge way. If we go AMD way we can save a couple of more Ks. I dont like Fusion as I didnt have an exactly good ecperience with it. However with Fusion you can come up with an HTPC for as low as 12-13K
Let me know your thoughts ....
