Hello, I am not sure where to place this, sorry in advance if I have the wrong area of the forum

I am building a new PC that will be accessed by about 5-10 other client PCs for reading/writing

Research:
I have read many articles about this an cannot come to a conclusion on what to use, as I am a beginner  in this field.
Many articles seem to over complicate the system/hardware for what my needs are

Security:
Security is not a big issue for me as all my PCs will have the same amount of access to files on the PC

Type of Reading/Writing:
MSWord, Access, Excel - simple programs which do not take a lot of space and can manage their own
Microsoft SQL Server Management is a requirement on this PC
Management to this PC can be done via Remote

Hardware:
1TB Hard Drive - More than enough storage for small MS office files
SSD - Windows 7 will be installed here, not sure if the SSD is even needed
8GB Ram - There will not be many applications/programs running in the background so this I think is already overkill
Processor - Not sure at this stage, probably going for whatever is cheap
Motherboard - Same as above
Graphics Card - Not sure if I need one, might just get a cheap one for basic things
Power Supply - Needs to be reliable and power efficient, as this PC will likely be on 24/7

What are you opinions on this setup?
Is it bad or wrong to use this PC like any other client PC?
