Do you mean put a TV tuner card IN the desktop?
If yes.... have thought of that as well.
Matter of fact I'm thinking of using a small cheap
Shuttle bare bones box from New Egg for this.
Don't know about Shuttle - but elected for modular (after considering
proprietary MB/Case setups) when I went that route (over a year ago).
A small but generic mini - lots of 'em on Newegg - that has two DVD
external slots. PS in most generics isn't great - if it has one, plan
on a replacement (better, probably, replaced ahead of time - mine had
one that shortly after crapped out). $60, all in all, for a $30 case/
crap PS - and $30 FORTRON PS replacement. Open-box $30 ASUS mini 478/
MB. Not very big, laying on its side in an entertainment center beside
a CARVER stereo amp. $20 for 512M of DDR. $40 for a retail w/fan
Intel Duron 2.4Ghz. $30 Logitec IR mouse/keyboard across on the coffee
table.
Add the above, right about $150. Discounting - It'd probably have to
be LGA 775 if I had to do it tomorrow.
(Factoring out 500G on two Seagate SATA HDs - a LiteOn SATA DVD burner
- NEC 37" HDTV/LCD 720P - spare Santa Cruz PCI SB overriding MB sound
chipset - and SYBA PCI SATA controller for the LiteOn. No cable
teevee - strictly OTA, though also have a LeadTek SD/Tuner-capture PCI
card installed, for now, crossed out of Device Manager without
drivers. ...Pretty much worthless, everything going ATSC this year)
