מה לשנות במחשב ישן?

היי,

אתמול לקחתי את המחשב של אח שלי, הוצאתי מהמארז ושמתי לו הארד דיסק.

זה מחשב והראד דיסק ממש ישנים, אז אני אשמח אם תגידו לי איזה חלקים הם הדפוקים ביותר ובמה צריך להחליף אותם, אני פשוט לא מבין בזה.

ואם אפשר חלקים לא יקרים מאוד ולא לגיימרים, המשחק היחיד שאח שלי מריץ זה מיינקראפט
