Don't need pins. Put on solder bumps and solder down.
BGA is only marginally cheaper than pins. You still have to
connect chip pads with something bigger. Flip chip helps.
Are you building a "thin client" or a PC?
Appliance PCs are more like smart clients. They're a full PC
as far as external machines are concerned. No troublesome
extra support required. No forced portals or render farms.
But with very limited local functionality.
It would surprise me if the parts cost of one of those
Dell 299 PC boxes is over 100 bucks,
AFIAK, MS-WinXP costs Dell ~$80, support ???. Price the parts out,
I don't think you can build for less than $150. Look at XBox1.
These toasters could be build around $100, or $50 in quantity:
No drives. Ultra cheap CPU (maybe not x86), 128 MB RAM (maybe
less), 64 MB flash video & sound, built in DOCSIS or DSL modem.
IR kbd/tb. Sealed box. Maybe with USB for expansion/drives.
What is the parts cost of a webtv box?
Isn't that what you are advocating?
I don't think so. AFAIK, webTV is reliant on WebTV render servers.
You're tied to them, and I don't think peope like being tied.
For those that do, AOL could give away (bundle) a customized box.
Svideo renders 640x480 surprisingly well even on NTSC TVs.
The real problem is that people may not want to browse/email in
a group.
