Thread quite long pero anyways some questions to owners here:
1) P5 for 30 minutes = Daghan pa gihapon mo sukol ani? Mingaw man gud ni ako 4 unit setup diri.

Naa ra baya unta ko sa main road sa subdivision namo.
depende sa lugar
2) In terms of setup, correct ba na kung ga Deep Freeze ka dapat ang games na cge up update like Cross Fire and DOTA 2 kay sa D:\ drive naka install?
have never used deep freeze, wala functionality to have read/write access sa drive.
have used Shadow Defender, kay maskin naka 'freeze' ang entire drive, pwede na-a exceptions nga certain folders kay na-a read/write access
3) Currently ako setup is 3 ka AMD APU units (A4-6300+6GB RAM +500GB HDD) and one Core 2 Duo unit with an AMD 5000 series video card plus 3GB of RAM. I plan to add and fortunately I have spare parts from my past life as a poster sa new rigs ani na forums...LOL....that can add 2 units usa kay Core 2 Duo and the other one sa a PDC E5500 both with 3GB RAM and a dedicated video card. DOTA 2 ug CF raman uso sa ako mga customers then naa sad to ang mag internet...so ok ra na ang Socket 775 para piso2x? Murag old school naman kaayo ang 775 gud.
don't make it too hard to yourself, if they are only playing DOTA2 and CF for those units, then if its still ok, then A-OK!!!
lisud man sab imo palitan ug high powered PC then duwa-on kay solitaire ra which is a good gayme ^_^
4) More advice than question ni but since 3 units are the same in my small piso2x setup......I went and used Macrium Reflect for cloning kung mo down ang hard drives. Piso2x owners might want to consider using that software as well.
if it works for you then its ok rasab ^_^
