Don't worry I haven't caught anything exotic, but my fingers are itching for another personal project (which will of course drive your mother up the wall).
Here is the result of the last project, most of the peripherals came from the old PC, but the motherboard, CPU, RAM, HDs and case were new.
It must have been some time in 2005, I'd met up with your uncle Chat at Pantip, bought all of the parts in the morning, when out for a few beers in the evening didn't get home until around midnight.
At around quarter past midnight, I said to myself, "I am not going to assemble it now (being a sensible person that I am), I'll go to bed and do it in the morning, as I should have a clear head by then"... "But... may be I could just unpack all the parts"... "now that is a great idea, so I shan't have to waste any time unpacking in the morning"...
To cut the long story short, 7 hours later I had finished putting my first PC together, and amazingly it booted up the first time with no problem (apart from a lot of swear words and praying along the 7 hours) (installing the CPU fan was a nightmare, especially after a few pints) (by the way, normal people would only perhaps need 2 - 3 hours, but your dad is different... strangely different :)
So it is time once again, I am thinking about a 'Caseless' PC (haven't told your mother yet, I don't think I am going to tell her until I have all the parts... hee hee). The only thing about going Caseless is the dust problem, have been looking at HSPC, their 'Techstation' looks interesting, but I don't think I can get it here (besides there is only room for 2 HDs, so I don't think I can make use of it anyway).
Now I am looking into 'Rack' system, most of them are huge (server) things... I'll keep you posted, unless your mother gets to me first :)
See you this Saturday :)
