The direct answer to your question is technically yes. There is at least one way via iCal in which you could set the computer to turn off at, say, 7:00 p.m. every Friday. You'd be assuming some risk by messing with that, FWIW. Additionally, there are a range of other toggles and whatnot in Settings and Preferences in which you could achieve some sort of auto-pilot that shuts her down or puts her to sleep, etc. And I'm pretty sure you can set the screen saver to never fade out. [Personally, I wouldn't do any of that. More below.]
Moreover, the anti-geek way of creating a "lamp" or signal device would be to plug a external hard drive (or flash drive) into one of the USB slots - and just leave it there whether you're using it or not. Every XHD and flash I own has an indicator light. Now, the ports are of course on the back, so this creates a bit of extra effort you could avoid by going with the XHD, which requires a cable, and thus, you can set it out front. Light is on, computer is on. And vicey-versy. By the way, flash and XHDs don't suck much from the processor when idling.
As previously mentioned, most computers, but especially Macs are designed to run interminably. Powering up and down is considerably rougher on the components.

I have a laptop here running for almost 10 years now 24/7 and it won't give up.
The laptop is a 450 mghz asus and I bought it second hand.
I, too, have had non-tube driven electronic devices last far beyond the standard usage threshold, which was mainly achieved by never turning them off except in extreme circumstance.
If you're worried about the ole girl blowing up from dodgy electricity, just make sure she's plugged into a surge protector and a power conditioner (I know, that's a bit much). From my experience, Apple is pretty good about self-preservation in that regard. Shit gets a little wild and she shuts herself down.

Another FWIW: A 27-inch iMac with Retina 5K display, 4.0GHz quad-core Intel Core i7, Turbo Boost up to 4.2GHz, 32GB 1867MHz DDR3 SDRAM, 1TB Flash Storage, AMD Radeon R9 M395X with 4GB video memory, Magic Mouse 2 + Magic Trackpad 2,Magic Keyboard, etc., is almost US$5,000 out the door
, tax and non-proprietary software not included. I would imagine Ms. Icon's company is balls-deep into some fancy publishing software you don't get from Microsoft Office - although that's not a knock on dem. Anyway, the point is, I could easily see dropping US$10k on the whole she-bang.
So...lemme ask you. Does that NT$25k TW PC have the chutzpah to run Adobe Photoshop, Illustrator, Premiere Effect, InDesign and Lightroom? At the same time?
Maybe, but good fuckin' luck with that. Meanwhile, let's say you're doing audio production. No way in hell I could manage Logic Pro (or equivalent) on a $800 PC. I would need at least $800 in monitors and speakers.
Anyway, I use the XHD method and I also never turn it off unless I'm going to be out of town for a week or longer - and sometimes I forget to do that.
